We demonstrate scaled high-Ge-content (HGC) strained SiGe pMOS FinFETs with very high short channel (SC) performance using a Replacement High-K/Metal Gate (RMG) flow, for the first time. A novel RMG gate stack process was introduced to create Ge-free interface-layer (IL) with excellent reliability and sub-threshold swing (SS) as low as 62mV/dec, the best reported to date for Si-cap-free SiGe FinFETs...
We demonstrate scaled High-Ge-Content (HGC) SiGe-OI finFET with Ge up to 71%, using a CMOS-compatible approach. For the first time, aggressively scaled HGC relatively-tall fins with vertical sidewalls and sub-10nm widths have been demonstrated using an enhanced 3D-Ge-condensation technique. An improved Si-cap-free HK/MG process featuring optimized IL has been developed resulting in scaled EOT and...

We demonstrate for the first time, Si1−xGex channel trigate PFETs on insulator with aggressively scaled fin width WFIN, gate length LG, and high-K/metal-gate stack (inversion oxide thickness TINV = 1.5 nm) using an implant-free raised source/drain (RSD) process. We report excellent electrostatic control down to LG = 18 nm for WFIN ≤ 18 nm. Using an optimized RSD process, we achieved high-performance...
