Investigation of CMOS devices with embedded SiGe source/drain on hybrid orientation substrates

Abstract

CMOS devices with embedded SiGe source/drain for pFETs and tensile stressed liner for nFETs have been demonstrated for the first time on hybrid orientation substrates. Ring oscillators have also been fabricated. Significant performance improvement is observed in hybrid orientation substrates compared to (100) control substrates with embedded SiGe.
