The Evolution of Computer Hardware When was the first transistor invented? l Modern-day electronics began with the invention in 1947 of the transfer resistor l Bardeen, Brattain & Shockley at Bell Laboratories
William Shockley Born in London, grown up in CA. B.S. 1932, Ph.D During WWII Anti-submarine research & bomber pilot training Report on casualty of invading Japan: 1.7m to 4m Presidential Medal for Merit Bell Labs Solid state physics group leader Invention of transistor in 1947 Silicon Valley Shockley Semiconductor Lab, Mountain View, CA Traitorous Eight formed Fairchild Semiconductor Robert Noyce, Gordon Moore, etc
The Evolution of Computer Hardware When was the first IC (integrated circuit) invented? l In 1958 the IC was born when Jack Kilby at Texas Instruments successfully interconnected, by hand, several transistors, resistors and capacitors on a single substrate
The PowerPC 750 Introduced in 1999 3.65M transistors 366 MHz clock rate 40 mm 2 die size 250nm technology
