Chapter 1
World War II was a defining moment in human history, with far-reaching impacts on technology, society and the global economy. The conflict was characterized by industrial attrition, with the United States’ production of tanks, ships and planes outpacing all the Axis powers combined. The experiences of Akio Morita in Japan, Morris Chang in China, and Andy Grove in Hungary, each illustrate the unique challenges faced by individuals during the war.
As the war drew to a close in 1945, many people speculated that a new Atomic Age was emerging, one defined by cutting-edge technologies such as rockets and radars. This was fueled in part by the rapid advancements in computing power that took place during the war. Before computers were invented, humans relied on abacuses and mechanical calculators for calculations, but this was a slow process that required considerable effort. The need for faster and more capable computing power during the war drove investment in the development of mechanical computers, which accelerated the field significantly.
During the Great Depression, a group of human computers was employed by the Works Progress Administration to perform complex calculations. However, even before the war, investment was flowing into projects to produce more capable mechanical computers, which were seen as a key tool for solving complex problems. One such example was the creation of mechanical bombsights, which were used to help aviators hit their targets. However, these devices had limited accuracy due to the fact that they only processed a limited number of inputs to produce a single output.
With the advent of electrical charges, early electric computers were able to perform a much wider range of calculations. This was made possible by the use of binary counting systems and vacuum tubes, which could be programmed to switch connections between them, enabling reprogramming capability. However, vacuum tube technology was too cumbersome, slow, and unreliable to be widely adopted. The ENIAC computer, for example, took up an entire room, but only multiplied hundreds of numbers per second faster than any mathematician, making it useful for niche applications like code breaking.
In conclusion, World War II was a turning point in the development of computing power, with the conflict driving investment in the field and accelerating technological advancements. From the use of abacuses and mechanical calculators to the development of early electric computers, the war had a profound impact on the field of computing and paved the way for the digital revolution that followed.
Chapter 2
William Shockley was a renowned physicist and theoretical physicist known for his groundbreaking work in semiconductors. He was born in London to a mining engineer and grew up in Palo Alto, California. Shockley received a degree from Caltech and went on to earn a PhD in physics from MIT. He worked at Bell Labs, one of the most influential centers of science and engineering at the time, and specialized in semiconductors, a class of materials that conduct current when certain materials are added and an electric field is applied.
Despite his obnoxious behavior, Shockley was considered a brilliant physicist, and in 1945 he theorized a “solid state valve” that would function as a valve opening and closing the flow of electrons. Despite his intuition and expertise, the electrical properties of semiconductors remained mysterious and unexplained until the late 1940s. Two of Shockley’s colleagues, Walter Brattain and John Bardeen, proved his theories correct by building a device that applied gold filaments to a block of germanium. This device, named the “transistor,” was useful for amplifying signals in phones and other devices, replacing vacuum tubes.
Shockley was angry and locked himself in a hotel room to create a new type of transistor, made up of three chunks of semiconductor material that could also act as a switch. Bell Labs held a press conference in June 1948 to announce their invention, but it wasn’t well received by the media. Despite this setback, Shockley went on to win a Nobel Prize in physics for his work on the transistor.
In conclusion, William Shockley was a pioneering physicist and theoretical physicist who made significant contributions to the field of semiconductors. His work on the transistor paved the way for modern electronics and earned him the recognition of the Nobel Prize in physics. Despite his obnoxious behavior, Shockley will always be remembered as a brilliant physicist and a pioneer in the field of electronics.
Chapter 3
William Shockley’s invention of the transistor brought about a revolution in the world of electronics. However, the challenge of mass-producing the transistor to replace the vacuum tubes was an engineering dilemma. Shockley established Shockley Semiconductor with the aim of building the best transistors and licensing the technology from AT&T. The transistor market was uncertain, and it was unclear whether transistors would take off as they needed to either perform better than vacuum tubes or be produced at a lower cost.
The complexity of the wiring between thousands of transistors in computers was a challenge, but Jack Kilby at Texas Instruments was trying to simplify it. Kilby was a brilliant and soft-spoken engineer who was one of the first outside of Bell Labs to use a transistor. Texas Instruments was originally founded to produce equipment using seismic waves for oil drilling but after World War II, they hired engineers to build military systems. Kilby arrived in Dallas during the company’s July holiday period and had time to tinker in the lab. He came up with the idea of assembling multiple components on the same piece of semiconductor material, resulting in the invention of the integrated circuit or chip.
Eight engineers from William Shockley’s semiconductor lab quit and founded their own company, Fairchild Semiconductor. These engineers, also known as the “traitorous eight,” are widely credited with founding Silicon Valley. Bob Noyce, the leader of the group, had a visionary enthusiasm for microelectronics. By the time Fairchild was founded, the science of transistors was clear, but manufacturing them reliably was still a challenge.
Jean Hoerni developed a method of fabricating all parts of a transistor by depositing a protective silicon dioxide layer on a slab of silicon, avoiding exposure to impurities and air. Robert Noyce realized Hoerni’s “planar method” could be used to produce multiple transistors on the same silicon chip, using lines of metal to conduct electricity between the transistors. Noyce’s version of the integrated circuit had no freestanding wires and was built into a single block of material.
Noyce and Gordon Moore realized that miniaturization and electric efficiency were a powerful combination. Noyce’s integrated circuit was vastly more reliable and easier to miniaturize than the mesa transistor, but initially, it cost 50 times more to make. Although Noyce’s invention was brilliant, it needed a market to be successful. The development of the transistor and the integrated circuit was a crucial turning point in the history of electronics, leading to the creation of modern-day computing and communication devices.
Chapter 4
The launch of Sputnik by the Soviet Union in 1957 created a crisis of confidence in the US and resulted in a crash program to catch up with the Soviet’s rocket and missile programs. President John F. Kennedy declared that the US would send a man to the moon, leading to an increased demand for guidance computers for the Apollo spacecraft.
This provided an opportunity for companies like Fairchild and Texas Instruments, who saw the potential in integrated circuits, to provide their chips to NASA. Robert Noyce, the co-founder of Fairchild, discounted prices for customers besides NASA, while Pat Haggerty of Texas Instruments saw the potential for Kilby’s integrated circuit to be used in all military electronics and made a successful bet on selling chips to the military.
The Minuteman II contract transformed TI’s chip business, with shipments to the Air Force accounting for 60% of all chip sales by 1965. The success of the Apollo computer was largely due to Noyce’s chips and the endorsement from NASA, while the military contracts from the Pentagon transformed TI’s chip business. The question remained whether TI could mass-produce the chips to meet the demand.
Chapter 5
Jay Lathrop, an MIT graduate with experience working in a U.S government lab, joined Texas Instruments (TI) on September 1, 1958. This was shortly after Jack Kilby’s productive summer spent in TI’s labs. At the time, Lathrop was grappling with the challenge of miniaturizing mesa-shaped transistors. His innovative solution was to use a microscope lens in reverse, effectively shrinking the image of the object under observation. This process, which came to be known as photolithography or printing with light, enabled him to manufacture transistors that were significantly smaller than before, measuring only one-tenth of an inch in diameter and 0.0005 inches in height.
Recognizing the potential of Lathrop’s process, Pat Haggerty and Jack Kilby saw its value as far exceeding the $25K prize offered by the Army. They understood that the use of light rays could mechanize chipmaking on an unprecedented scale. However, implementing lithography at TI necessitated the development of new materials and processes. This included purchasing their own centrifuges to ensure the purity of chemicals, creating their own masks due to a lack of precision elsewhere, and sourcing ultra-pure silicon wafers that were not available elsewhere.
Mass production of components presented challenges due to impurities, variations in temperature and pressure, and contamination by dust particles. In response, TI conducted thousands of experiments to evaluate the effects of different temperatures, chemical combinations, and production processes. Morris Chang played a crucial role in improving TI’s manufacturing yield through his methodical approach, while Mary Anne Potter conducted round-the-clock tests to scale up chip production for the Minuteman missile.
Meanwhile, at Fairchild Semiconductor, Robert Noyce hired James Nall from Lathrop’s lab to develop photolithography. Andy Grove, a refugee from Hungary’s Communist government, worked on enhancing their manufacturing process. While William Shockley, the inventor of transistors, was awarded a Nobel Prize for his contribution, it was engineers like Chang who, through trial and error, transformed these inventions into practical products. By the mid-1960s, their efforts had enabled the mass-market productization of these technological advancements.
Chapter 6
Bob Noyce, a co-founder of Fairchild Semiconductor, recognized the significance of the military and space applications to the company’s early success. However, Noyce also envisioned a much larger civilian market for integrated circuits. To tap into this market, Noyce declined most military research contracts and focused on developing mass-market products from chips used in rockets or satellites. The first integrated circuit produced for commercial markets was designed for a NASA satellite and used in a Zenith hearing aid. Despite the presence of defense contractors, the Pentagon underestimated the speed at which startups like Fairchild would transform electronics due to their agility compared to big bureaucracies.
Gordon Moore, the director of Fairchild R&D, not only devised new technology but opened new civilian markets as well with his prediction of exponential growth in computing power, known as “Moore’s Law.” Moore realized that the integrated circuit would revolutionize society beyond just rockets and radars. The military demand for features in chips that were also useful for business applications led to a surge in civilian chip sales. Robert McNamara’s defense reforms resulted in Fairchild offering off-the-shelf integrated circuits at significantly lower prices, thereby expanding the market for chips.
By 1968, the computer industry was buying as many chips as the military, and Fairchild’s products served 80% of this market due to Bob Noyce’s price cuts. The Apollo 11 mission used a guidance computer powered by Fairchild’s integrated circuits. However, Silicon Valley engineers had become less reliant on defense contracts as the booming chip market became their focus. This financial success fueled the progress of Moore’s Law while employees sought ways to make money from it. Even Noyce himself considered leaving the company at some point.
In conclusion, Fairchild Semiconductor’s journey from military applications to civilian applications was driven by a combination of visionary leaders, market demand, and favorable defense reforms. This shift resulted in the exponential growth of the computer industry and the rise of Silicon Valley as a technology hub.
Chapter 7
Bob Noyce was a renowned inventor who revolutionized the electronics industry with his invention of the integrated circuit at Fairchild Semiconductor. At the same time, the Soviet Union and the United States were competing in various fields, including semiconductors and their role in transforming manufacturing, computing, and military power. Anatoly Trutko, a Soviet semiconductor engineer, arrived at Stanford University for a student exchange program during the Cold War. Trutko studied under William Shockley, who was upset that the USSR refused to pay royalties for the Russian translation of his textbook.
The USSR assigned its smartest scientists to work on building its semiconductor industry, including Yuri Osokin who was tasked with building an integrated circuit with multiple components. Osokin and his colleagues spent their time in the lab and debating solid-state physics, and Soviet leader Nikita Khrushchev was obsessed with competing with the United States. Alexander Shokin, a Soviet State Committee on Radioelectronics official, saw an opportunity to use Khrushchev’s urge to compete to win investment in microelectronics.
The USSR had a secret weapon in the form of a spy ring led by Julius Rosenberg, which included Joel Barr and Alfred Sarant, electrical engineers and members of the Communist Party. During the 1940s, Barr and Sarant worked on classified military systems and gained knowledge about electronics before fleeing the US to reach the Soviet Union. In the Soviet Union, Barr and Sarant told KGB handlers they wanted to build the world’s most advanced computers and eventually built the first computer called UM.
Barr and Sarant partnered with Shokin to convince Khrushchev to establish a city devoted to producing semiconductors, and dreamed up their own version of Silicon Valley in a Moscow suburb. Sarant and Barr, former spies, showed Khrushchev the cutting-edge advancements in Soviet microelectronics and presented the idea of a futuristic city dedicated to producing semiconductors, which Khrushchev enthusiastically endorsed. The Soviet government approved the plan to build a semiconductor city in the Moscow outskirts, called Zelenograd, which was designed to be a perfect scientific settlement with all amenities for semiconductor engineers. The Moscow Institute of Electronic Technology, a university, was near the center of Zelenograd and resembled American and English college campuses.
In conclusion, Bob Noyce’s invention of the integrated circuit at Fairchild Semiconductor was paralleled by the Soviet Union’s efforts to build its semiconductor industry. The USSR had a secret weapon in the form of a spy ring led by Julius Rosenberg, which included Barr and Sarant, and eventually built a city devoted to producing semiconductors in the Moscow outskirts. Zelenograd was designed to be a perfect scientific settlement with all amenities for semiconductor engineers and resembled American and English college campuses.
Chapter 8
Nikita Khruschev’s support for building the Soviet microelectronics center, Zelenograd, coincided with the return of Soviet student Boris Malin from studying in Pennsylvania with an integrated circuit. Alexander Shokin, the bureaucrat in charge of Soviet microelectronics, ordered scientists to copy the integrated circuit one-for-one without deviation, without fully understanding the implications of this strategy. The Soviets had some of the world’s leading theoretical physicists and Jack Kilby was awarded the Nobel Prize for inventing integrated circuits, but their production process lacked the sophistication and purity needed to mass-produce chips reliably. Spying could only get them so far, as specialized knowledge was often not written down or shared outside company walls.
The cutting edge of semiconductor technology was constantly changing, as per Moore’s Law, with TI and Fairchild introducing new designs with more transistors every year, making the earliest integrated circuits obsolete. The size of transistors and their energy consumption were shrinking while computing power packed in a square inch of silicon doubled roughly every two years. The Soviet leaders failed to understand that copying old designs condemned them to backwardness, with their chipmaking machinery even using inches instead of centimeters for better replication from American models. This “copy it” strategy meant that they started several years behind the US, never catching up due to a lack of creativity and market exploration, with civilian products being an afterthought amid military production focus.
Zelenograd became a poorly run outpost in the Silicon Valley, with pathways for innovation set by the US, with American chipmakers at its center. The Soviet microelectronics center was unable to keep up with the rapid pace of change in the semiconductor industry, and the lack of market exploration and creativity doomed it to failure. The US remained at the forefront of the semiconductor industry, leading the world in chip design and production, while Zelenograd remained a footnote in the history of the integrated circuit.
Chapter 9
In November 1962, Hayato Ikeda, the Japanese Prime Minister, visited French President Charles de Gaulle at the Elysée Palace and presented him with a Sony transistor radio. This gesture symbolized the rise of Japan as an economic power, a journey that began in the aftermath of World War II. The US had a Cold War strategy of integrating Japan into its semiconductor industry and supporting the rebuilding of its economy. This allowed Japanese scientists access to important journals and research in the field, leading to the creation of electronics giants like Sony.
Founded by Akio Morita and Masaru Ibuka, Sony was focused on innovation and product design, rather than copying tactics used by other companies. Their first major success was the transistor radio, a product that had previously been attempted by Texas Instruments but was hampered by pricing and marketing errors. Throughout the 1960s, US chipmakers dominated the production of cutting edge chips, but Japanese firms, including Sony, paid hefty licensing fees for intellectual property rights and eventually became experts in devising consumer electronics.
In the 1970s, Sharp Electronics revolutionized the calculator market, making most calculators Japanese-made. The interdependence between America and Japan involved both countries relying on each other for supplies and customers. The US built advanced computers while Japan focused on producing consumer goods, with semiconductors driving growth in consumption. Morita helped Texas Instruments open its first foreign chipmaker plant in exchange for a share of profits, tying Japan even more closely into the US-led system.
In conclusion, Hayato Ikeda’s visit to the Elysée Palace and the gift of the Sony transistor radio marked the arrival of Japan as an economic power. The rise of Sony and other electronics giants was due to the interplay of technology, innovation, and government support, and it helped achieve Ikeda’s goal of doubling the country’s incomes in just a decade.
Chapter 10
In the early days of the semiconductor industry, men were the primary designers while women were responsible for assembly. As the demand for semiconductors grew, the need for larger and cheaper labor forces also grew, leading to the rise of chip startups in the Santa Clara Valley south of San Francisco.
Charlie Sporck, an expert in productivity optimization, was hired by Fairchild Semiconductor after a union revolt forced him to leave his previous job at GE. He implemented efficiency strategies and gave most employees stock options as an incentive for increased productivity levels.
In contrast to the electronics firms on the East Coast, most of the new chip startups in the Santa Clara Valley employed women to staff their assembly lines. The 1965 immigration law increased the foreign-born labor pool and made it easier for chip firms to hire women at lower wages and without demanding better working conditions. Production managers believed that smaller hands gave female workers an advantage when assembling and testing semiconductors.
As demand continued to grow, chip firms began to look for even cheaper labor and opened facilities in locations such as Maine or on a Navajo reservation due to tax incentives. Bob Noyce even invested in a radio assembly factory near the border of Hong Kong, where wages were only 25 cents per hour. The Fairchild factory in Kowloon Bay, Hong Kong, became one of their most successful facilities, producing high-quality semiconductors thanks to the trained engineers running the assembly lines.
Overall, the early semiconductor industry relied heavily on the work of both men and women, with men as the designers and women as the assembly workers. The need for larger and cheaper labor forces led to the expansion of the industry to various locations, including the Santa Clara Valley and abroad.
