What is a Silicon Substrate?

In semiconductors a silicon wafer is also referred to a silicon slice and silicon substrate. Think of a substrate like a wall which can be painted on, or wall papered. It's the base for which microelectronics are etched onto the surface.

Each silicon substrate diameter has a semiconductor standard thickness. For example 100mm silicon substrate standare thickness is 550 microns +/-25 microns. Crystalline silicon (c-Si) subsrate is processed into Integrated Circuits (ICs) and solar applications. The silicon substrate is the base used to fabricate micro-electronic devices on the surface.

The steps to make a silicon subsrate chip includes:

  • Doping
  • Ion Implantation
  • Etching
  • Thin-film deposition
  • photolithographic
