摘要: At least one drain-side surfaces of a field effect transistor (FET) structure, which can be a structure for a planar FET or a fin FET, is structurally damaged by an angled ion implantation of inert or electrically active dopants, while at least one source-side surface of the transistor is protected from implantation by a gate stack and a gate spacer. Epitaxial growth of a semiconductor material is retarded on the at least one structurally damaged drain-side surface, while epitaxial growth proceeds without retardation on the at least one source-side surface. A raised epitaxial source region has a greater thickness than a raised epitaxial drain region, thereby providing an asymmetric FET having lesser source-side external resistance than drain-side external resistance, and having lesser drain-side overlap capacitance than source-side overlap capacitance.

摘要: A method of making a silicon-on-insulator (SOI) semiconductor device includes etching an undercut isolation trench into an SOI substrate, the SOI substrate comprising a bottom substrate, a buried oxide (BOX) layer formed on the bottom substrate, and a top SOI layer formed on the BOX layer, wherein the undercut isolation trench extends through the top SOI layer and the BOX layer and into the bottom substrate such that a portion of the undercut isolation trench is located in the bottom substrate underneath the BOX layer. The undercut isolation trench is filled with an undercut fill comprising an insulating material to form an undercut isolation region. A field effect transistor (FET) device is formed on the top SOI layer adjacent to the undercut isolation region, wherein the undercut isolation region extends underneath a source/drain region of the FET.
