Abstract

We demonstrate high performance Ge n-MOSFETs with novel raised source/drain fabricated on high quality single crystal Ge selectively grown heteroepitaxially on Si using Multiple Hydrogen Anealing for Heteroepitaxy(MHAH) technique. Until now low source/drain series resistance in Ge n-MOSFETs has been a highly challenging problem. Source and drain are formed by implant-free, in-situ doping process for the purpose of very low series resistance and abrupt and shallow n+/p junctions. The novel n-MOSFETs show among the highest electron mobility reported on (100) Ge to-date. Furthermore, these devices provide an excellent Ion/Ioff ratio(4× 103) with very high Ion of 3.23μA/μm. These results show promise towards monolithic integration of Ge MOSFETs with Si CMOS VLSI platform.
