Abstract

Silicide formation on strained GexSilx layers by the thermally-induced metal/GexSi1−x reaction results in enhanced relaxation of the underlying strained layer. Silicide formation on an amorphous layer is a potential means of decreasing processing temperatures, increasing reacted-layer/GexSi1−x interface planarity and hence, decreasing strained layer relaxation. For the present report, the thermally-induced Co/Ge.17Si.83 reaction on crystalline and amorphous substrates at temperatures of 500-600°C has been compared. Though the rate of silicide formation increased with amorphous substrates, strained layer relaxation was not inhibited.
