Jack Kilby was new at Texas Instruments in 1958. That summer, most of his colleagues took the company's vacation. Kilby hadn't been there long enough to earn the time off, so he stayed in the lab in Dallas and kept working on a problem the whole industry was stuck on.
Electronics were getting more complicated, and every component in a circuit had to be made separately and then wired to the others. More parts meant more connections, and every connection was another thing that could fail. The work kept growing, and nobody had found a way around it.
Kilby's idea was to stop wiring things together at all. If every part of a circuit could be formed from a single piece of semiconductor material, there would be nothing left to connect.
On September 12, 1958, he showed it to TI's management: a phase-shift oscillator built on a sliver of germanium about seven-sixteenths of an inch long. It worked.
TI filed the patent the following February. Robert Noyce, working separately at Fairchild Semiconductor in California, developed a silicon version that made the chip practical to manufacture, and the two are generally credited together. In 2000, Kilby received the Nobel Prize in Physics for the invention.
What we take from it
- Constraints aren't the opposite of invention.No vacation, a quiet lab, and a problem everyone had learned to live with. Some of the best fixes come from the person who's still there when everyone else has gone home.
- Show the working thing.Kilby didn't send management a memo about miniaturization. He put a working circuit in front of them. We try to work the same way: you see the fix running before you commit to anything.
- The breakthrough removed steps.The chip's whole point was fewer things to connect by hand. That's still the test for any new tool: it should do the work, not add another thing to manage.
Sixty-eight years later, the future of work still has a Texas address.
