Semiconductor production technology in terms of fitting more circuits in limited space advances interminably. In the 1950s, an electronic chip had only ten circuits. This increased a hundredfold in the 1960s. It is said that the capacity of chips rises every two years. In the end of the 1980s, a stamp-sized could contain 16 million circuits. In the past years, up to 7 to 10 billion circuits could be fitted in this small space
Special technologies are used to etch circuits on silicon wafers (8-12 inches). The most advanced machines could print 7 nanometer circuits. (In comparison, the diameter of common human hair is 80,000 to 100,000 nm.) The capacity to print 5 nm and 3 nm circuits are now being developed.
