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).
Recommended products
Stainless steel regulators Z527416 or Z527424 are recommended.
