Features and Benefits

Germane gas is used in the deposition of epitaxial and amorphous SiGe alloy layers used in the production of high performance devices including photovoltaic cells and integrated circuits (IC). Precursor to germanium-containing thin films by chemical vapor deposition (CVD) and molecular beam epitaxy (MBE). A CVD precursor for germanium carbide semiconducting films.

Recommended products

Stainless steel regulators Z527416 or Z527424 are recommended.
