What are the sizes of silicon chips?

Small silicon chips may be no more than 1/16” square by 1/30” thick and hold up to tens of thousands of transistors. Large chips, the size of a postage stamp, can contain hundreds of millions of transistors.

Chip Size Number of Transistors per Chip
SSI—small-scale integration Less than 100
MSI—medium-scale integration Between 100 and 3,000
LSI—large-scale integration Between 3,000 and 100,000
VLSI—very-large-scale integration Between 100,000 and 1 million
ULSI—ultra-large-scale integration More than 1 million
