Abstract
Highly-strained Ge-in-STI pFETs on SiGe55% SRBs are demonstrated with mobilities up to 550 cm2/Vs and record NBTI reliability at TINV~1.7 nm. Short channel sGe pFET devices down to 35nm gate length are also reported. This work makes the first use of a germanide in contacts to solve void issues and a high Ge (75%) SiGe S/D for strain enhancement of mobility with an RMG flow providing module learning portable to FinFETs.
