The Chip: How Two Americans Invented the Microchip and Launched a Revolution by T. R. Reid
4.0
The Chip is a humanistic look at one of the key inventions of the 20th century, the microchip which undergirds every digital change to our life. Thanks to chips, "just put a computer in it" has been a solution to almost every engineering problem, and the cause of a similar number of engineering problems.
In the 1950s, the electronics industry was carrying a blade with no handle. The silicon transistor had opened up vast possibilities by replacing large, power-hungry, and unreliable vacuum tubes. But the new solid state circuits were still built the same way, by wiring together discrete components like resistors, capacitors, and transistors, and the labor cost of hand wiring all these components was stalling future growth. Worse, as the complexity of circuits increased, their reliability went way down, a fatal flaw for aerospace and military applications.
Kilby at Texas Instruments and Noyce at Fairchild Semiconductor hit on the key idea at roughly the same time. If you could lay down resistors, capacitors, and wires inside silicon, you could make a circuit as a monolithic unit. Kilby was first by several months, but Noyce figured out how to get the leads between the chip and world laid down, which is a very important step. Doing everything in silicon is counter-intuitive, by raw materials it's comparable to building a boxcar out of solid gold, but the advantage in not having to wire together components is incredible. Cue the digital revolution that we know, though from the perspective of decades on the revolution was slower than we remember. The first few years of production went entirely to the military. The consumer product which blew the world open was the pocket calculator, which came out in 1971, 15 years after the invention of the chip.
Reid follows the rise of Japanese firms in high tech, as well as the divergent careers of Noyce and Kilby. Noyce went on to become the patriarch of Silicon Valley and a billionaire investor. Kilby kept inventing, though never with the same success. He was finally awarded the Nobel Prize in 2000, but neither of the two are household names despite their impact as inventors.
Reid also makes some odd choices in the technical explanations. There's a lot on Boolean algebra and binary logic, which is key to how chips work, and precisely nothing on photolithography, which is key to how they're made. This is an older book, which is beneficial because there's nothing like interviews with your subjects to get the right feeling across, and Noyce and Kilby are no longer available for interviews.
