摘要

成功地开发了一种STI-last集成方案,用于制造低缺陷和掺杂控制的SiGe SRB / sGe鳍。首次证明了15 nm鳍宽SiGe SRB/高应变Ge pfinfet的栅极长度降至35 nm。采用cetv标准化GM,SAT,INT为6.7 nm。mS/μm, Si0.3Ge0.7 / sGe pfinfet的性能比目前最先进的松弛ge finfet提高了90%。

15nm-WFIN high-performance low-defectivity strained-germanium pFinFETs with low temperature STI-last process
An STI-last integration scheme was successfully developed to fabricate low-defectivity and dopant-controlled SiGe SRB / sGe Fins. For the first time, 15 nm fin-width SiGe SRB/highly-strained Ge pFinFETs are demonstrated down to 35 nm gate length. With a CETINV-normalized GM,SAT,INT of 6.7 nm.mS/μm, the Si0.3Ge0.7 / sGe pFinFETs presented in this work improve the performance by ~90% as compared to the state-of-the-art relaxed-Ge FinFETs.
