Thermal Oxide on Silicon Substrate
Wet and dry thermally grown oxide available. Wet grows on both sides of the wafer by default. Dry oxide can be grown on just one side and can be less than 200nm. Buy SiO2 coated silicon substrates.
Silicon Nitride (SiN) on Silicon Substrates
We have the following nitride growth methods:
Low Stress Nitride
Super Low Stress Nitride
PECVD Nitride

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
