    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 semiconductor substrate having an isolation region and method of forming the same. The method includes the steps of providing a substrate having a substrate layer, a buried oxide (BOX), a silicon on insulator (SOI) layer, a pad oxide layer, and a pad nitride layer, forming a shallow trench region, etching the pad oxide layer to form ears and etching the BOX layer to form undercuts, depositing a liner on the shallow trench region, depositing a soft mask over the surface of the shallow trench region, filling the shallow trench region, etching the soft mask so that it is recessed to the top of the BOX layer, etching the liner off certain regions, removing the soft mask, and filling and polishing the shallow trench region. The liner prevents shorting of the semiconductor device when the contacts are misaligned.
