    摘要: Embodiments of the invention provide a relatively uniform width fin in a Fin Field Effect Transistors (FinFETs) and apparatus and methods for forming the same. A fin structure may be formed such that the surface of a sidewall portion of the fin structure is normal to a first crystallographic direction. Tapered regions at the end of the fin structure may be normal to a second crystal direction. A crystallographic dependent etch may be performed on the fin structure. The crystallographic dependent etch may remove material from portions of the fin normal to the second crystal direction relatively faster, thereby resulting in a relatively uniform width fin structure.

    摘要: A semiconductor structure that includes a monocrystalline germanium-containing layer, preferably substantially pure germanium, a substrate, and a buried insulator layer separating the germanium-containing layer from the substrate. A porous layer, which may be porous silicon, is formed on a substrate and a germanium-containing layer is formed on the porous silicon layer. The porous layer may be converted to a layer of oxide, which provides the buried insulator layer. Alternatively, the germanium-containing layer may be transferred from the porous layer to an insulating layer on another substrate. After the transfer, the insulating layer is buried between the latter substrate and the germanium-containing layer.

    摘要: A semiconductor structure for a dynamic random access memory (DRAM) cell array that includes a plurality of vertical memory cells built on a semiconductor-on-insulator (SOI) wafer and a body contact in the buried dielectric layer of the SOI wafer. The body contact electrically couples a semiconductor body with a channel region of the access device of one vertical memory cell and a semiconductor substrate of the SOI wafer. The body contact provides a current leakage path that reduces the impact of floating body effects upon the vertical memory cell. The body contact may be formed by an ion implantation process that modifies the stoichiometry of a region of the buried dielectric layer so that the modified region becomes electrically conductive with a relatively high resistance.

A portion of a doped semiconductor fin may protrude through a first doped layer. An intrinsic layer may be disposed on the protruding semiconductor fin. A second semiconductor layer may be disposed on the intrinsic layer, thereby forming a PIN diode compatible with FinFET technology and having increased junction area.
