摘要:
A MOSgated trench device has a reduced on resistance by forming a less than about a 13 nm thick strained SiGe layer on the silicon surface of the trenches and forming a thin (30 nm or less) layer of epitaxially deposited silicon on the SiGe layer which epi layer is converted to a gate oxide layer. The conduction channel formed by the SiGe layer is permanently strained to increase its mobility particularly hole mobility.

摘要:
A process for fabricating power semiconductor devices involving preparation of a silicon wafer by epitaxial formation of an intrinsic silicon layer on a silicon substrate and high energy implantation to form channel and drift regions in the intrinsic epitaxial silicon.
摘要:
A method of fabricating a MOSFET wherein sidewall spacers are provided adjacent the gate of the MOSFET, the method including the steps of providing an insulating layer which extends over the source, drain and gate of the MOSFET and which acts as an impurity diffusion barrier; and forming on the insulating layer sidewall spacers which are composed of an insulating material.
