Abstract
The electrical properties of surface- and buried-channel p-MOSFETs containing strained GeSi heterostructures synthesized by high-dose Ge implantation and solid phase epitaxial growth have been investigated. Compared with Si control devices on the same chips, GeSi transistors exhibited improved performance: the channel hole mobility and linear transconductance was up to 18% higher for surface-channel GeSi transistors, and up to 12% higher for buried-channel GeSi p-MOSFETs, than for equivalent Si devices. Ion-beam synthesis of GeSi strained layers therefore offers an attractive means for realising improved device performance in conventional Si device structures.
