Nonselective germanium deposition by UHV/CVD










Image Number 6 for United States Patent #5286334.

A method of depositing Ge on a Si substrate in a reaction chamber includes the steps of: precleaning the substrate; evacuating the chamber to a pressure below 10.sup.-7 Torr; heating the substrate to 300.degree.-600.degree. C.; and providing a GeH.sub.4 /B.sub.2 H.sub.6 /He mixture of gas with a GeH.sub.4 partial pressure of 2-50 mTorr and a B.sub.2 H.sub.6 partial pressure of 0.08 to 2 mTorr.
