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.
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.
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.
A: two types on a experimental type is called breadboard on a functional circuit is called mother board
microchips
Most sand is composed of quartz - silicon dioxide. The element silicon is used to make microchips.
Circuit cords, wires, microchips, and electronica things
They are made from silicon
Microchips are generally manufactured using photo-lithography to control the placement of semiconductors. The semiconductors are made by doping the metal to alter its electrical properties
You would say the latter. eigh percent of microchips ARE defective
NO !
no they are not

Microchips are used today as implants in living bodies to aid in tracking and identification.
