ABSTRACT
Aflexible epi deposition system has been developed which enables SiGe alloys of varying composition to be grown and is compatible with silicon p roduction epitaxy in the same apparatus without c ross contamination. The use of load locking and high vacuum integrity minimises gas and water vapour contamination and the use of high system gas flows t h roughout the epi process further reduces the contaminant levels to those orders achieved by U.H.V.
