The development of the integrated circuit (IC) was largely determined by the density of transistors on a chip
one thousand (10exp3) to ten thousand (10exp4) transistors per chip and were developed in the mid-1960s. Thestructure width for LSI technology was 10 µm to 50 µm, and analog-to-digital circuits, memory devices, and microprocessors
were designed in this technology. The successor technology to Large Scale Integration is Very Large Scale Integration (VLSI).
