INTEGRATED CIRCUITS

In the late 1960 came the integrated circuit (IC), which enabled the production of multiple transistors on a single silicon substrate in which the interconnecting cables were soldiers. The integrated circuit allowed a further reduction in price, size and error rates. The microprocessor has become a reality in the mid-1970, with the introduction of circuit large scale integration (LSI stands for Large Scale Integrated) and, later, with the circuit on a larger scale integration (VLSI, acronym for Very Large Scale Integrated), with several thousand soldiers interconnected transistors on a single silicon substrate.
