1958 Jack St Clair Kilby demonstrates the world’s first integrated circuit to fellow researchers and executives at Texas Instruments (TI). The circuit contains five components, including germanium mesa transistors, resistors, and capacitors linked by wires, on a piece of germanium half an inch long and thinner than a toothpick. The purpose of the demonstration is to prove that resistors and capacitors can exist on the same piece of semiconductor material. The circuit was designed while
