Abstract

ABSTRACTA rapid radiant heating, very low pressure CVD (RRH/VLP—CVD) has been successfully applied to GexSi1−x strained layer epitaxy on Si using SiH4' GeH4' B2H6 and PH3 as reaction gases at low temperature ranging from 550 to 650ĉ for operation pressure around mTorr. High quality GexSi1−x/Si strained layer heterostructure and superlattice were fabricated and high electrically active in—situ boron doping in GexSi1−x epilayer was also successfully achieved.
