Germanium tetrafluoride has long been the standard dopant gas of choice for germanium implantation processes. While this material maintains several positive attributes (, it is a nonflammable gas that is easily delivered to an ion source), its use can result in extremely short ion source lifetimes.

This work describes a process of Si epitaxy on a (100)Ge surface using a SiH4–H2 gas low‐pressure chemical‐vapor deposition (LPCVD) system. Germanium epitaxial film formed on (100)Si wafers using GeH4–H2 gas in a LPCVD reactor was used as the experimental substrates. It was found that Si grew epitaxially through a SiH4 thermal decomposition reaction on the clean Ge surface within a ...

germanium

Germanium is in the same chemical family as carbon, silicon, tin, and lead. Consequently, it resembles these elements in the process of forming organic compounds, such as tetraethyl germanium and tetraphenyl germanium. At room temperature, germanium is unreactive and it does not react with hydrochloric acid.
