Where did Jack kibly invent the microchip?

Answer 1

Kilby had been hired by Texas Instruments to work on "miniaturization". The first project he worked on involved constructing circuits from discrete components that could be inserted into tubular packaging. He did a cost analysis and found that the approach would be neither practical or profitable for manufacturing. His fundamental insight, during the summer of 1958, was that, considering Texas Instruments was primarily a semiconductor manufacturer (already making an enormous number of transistors), the only cost-effective way to make the components would be to make them all out of semiconductor material. He had some technicians in the lab make some resistors and capacitors in silicon. He then wired the pieces together to make a flip-flop, to demonstrate the concept. His boss, Willis Adcock, gave him the go-ahead to try to make all the components on one piece of semiconductor material. Kilby drew a sketch of a circuit (a phase-shift oscillator) and had prototypes built in the lab. It took two weeks to prepare three tiny bars of germanium containing the circuits. Each one was mounted on a glass slide. The first working circuit was tested on September 12, 1958.

Jack St.Claire Kilby invented the microchip at TI's new Semiconductor Building in July of 1958
