Features and Benefits
Methylsilane is used in the plasma-assisted CVD of silicon carbide (SiC) and as a precursor to the epitaxial growth of SiGeC alloy layers via rapid thermal CVD.1 Recent developments include the use of methylsilane as a precursor to silicon-carbon-hydrogen polymer used as photoresists.
Precursor to silicon carbide or alloy thin films by chemical vapor deposition (CVD) and molecular beam epitaxy (MBE).
