- Abstract
Incorporation of high amount of boron in the range of 1 × 1020–1 × 1021 cm−3 in selective epitaxial growth (SEG) of Si1 − xGex (x = 0.15–0.315) layers for recessed or elevated source/drain junctions in CMOS has been studied. The effect of high boron doping on growth rate, Ge content and appearance of defect in the epi-layers was investigated. In this study, integration issues were oriented towards having high layer quality whereas still high amount of boron is implemented and the selectivity of the epitaxy is preserved.
