In 1958-1959 two men were working on the idea for different companies. One was Jack Kilby with Texas Instruments and the other was Robert Noyce who began Fairchild Semiconductor which will become Intel. Kilby has 60 patents to his name and is known as the inventor of portable calculator. His microchip was first used by the government for the minuteman missle. Noyce has 16 patents to his name.

D. Processing power of microchips doubles every 18 months.
Yes they all do.AnswerNo, they don't. There are many p.c.bs which use only discrete components.
THE SILICON CHIP -The term silicon is important in the computer industry. Microchips that let computers work are made from silicon. Scientists developed the first trial silicon chip in 1958. Before that time computers were made of transistors. In 1958 scientists thought that silicon microchips were impressive because each chip could hold more than 30 transistors. Today's silicon chips often have more than a million transistors. Silicon microchips have helped make modern computer technology possible.
The first integrated circuit masks were hand made, then optically reduced. The wafers were then processed much as they are today using these reduced masks. Hand made masks were used well into the 1970s. All the early microprocessors were done with hand made masks. You can even download from Intel's website now masks and schematics, all hand drawn, for their original 4004.
