Integrated Circuit Mass
How Much does a Chip Weigh?
CMOS (Complimentary Metal Oxide Semiconductor) integrated circuit chips are made N type and P type MOS field effect transistors, wiring, insulators, on top of a silicon substrate. The zoo of devices on all integrated circuits includes bipolar transistors, diodes, capacitors, loop inductors, diffused and thin-film resistors, sometimes even special sensors like avalanche photodiodes. However, almost everything we do with server sky will involve advanced-process CMOS, with some DRAM ( Dynamic Random Access Memory ) using stack capacitors and some flash (block rewritable) EEPROM ( Electrically Eraseable Programmable Read Only Memory, which writes information by trapping charges in the insulators of MOS gates.
These are all planar processes produced by photolithography.
