HMDS | Scientific.Net

Abstract: Selective epitaxial growth (SEG) of cubic silicon carbide (3C-SiC) was carried out on patterned Si (100) substrates using SiO2 as a mask. The growth was performed by atmospheric pressure chemical vapour deposition in a resistance-heated furnace using hexamethyldisilane (HMDS) as the source.

Vacuum Deposition Processes

Vacuum deposition is a generic term used to describe a type of surface engineering treatment used to deposit layers of material onto a substrate. The types of coatings include metals (e.g., cadmium, chromium, copper, nickel, titanium) and nonmetals (e.g., ceramic matrix composites of carbon/carbon, carbon/silicon carbide, etc.), deposited in thin layers (i.e. atom by atom or molecule by
