Sep 12, 2019 · Kilby’s first working integrated circuit contained a single transistor and supporting components on a slice of germanium, measuring 1/16 × 7/16 in. (1.6×11.1 mm).
While Kilby’s invention was not for monolithic-IC, he did anticipate some of the monolithic concepts for the devices and their isolation in an IC. But Kilby missed the key concepts of monolithic interconnects and planar technology necessary to fabricate monolithic-IC.
Kilby’s notebook has the first diagram of an integrated circuit where all components were made of the same material. The integrated circuit concept was accepted around 1960 and many applications followed, beginning with the pocket calculator in 1964.
Nov 19, 2023 · Jack St. Clair Kilby successfully miniaturized a complete electronic circuit onto a tiny chip no larger than a pencil eraser. This revolutionary invention, the integrated circuit, paved the way for modern computing technology as we know it.
Kilby etched separate transistor, capacitor, and resistor elements on a single germanium slice, then connected them with fine gold “flying” wires into oscillator and amplifier “solid circuits.”
Jack Kilby’s demonstration of the first working integrated circuit (IC) in 1958 revolutionized the field of microelectronics. Instead of using discrete transistors, resistors, and capacitors to form a circuit, Kilby’s IC design integrated a transistor, a capacitor, and the equivalent of three resistors all on the same chip.
