    Abstract: A FinFET split gate EEPROM structure includes a semiconductor substrate and an elongated semiconductor fin extending above the substrate. A control gate straddles the fin, the fin's sides and a first drain-proximate portion of a channel between a source and drain in the fin. The control gate includes a tunnel layer and a floating electrode over which are a first insulative stratum and a first conductive stratum. A select gate straddles the fin and its sides and a second, source-promixate portion of the channel. The select gate includes a second insulative stratum and a second conductive stratum. The insulative strata are portions of a continuous insulative layer covering the substrate and the fin. The conductive strata are electrically continuous portions of a continuous conductive layer formed on the insulative layer.

  • Patent number: 7074692
    Abstract: Methods of reducing a short channel phenomena for an NMOS device formed in an SOI layer, wherein the short channel phenomena is created by boron movement from a channel region to adjacent insulator regions, has been developed. A first embodiment of this invention entails the formation of a boron or nitrogen doped insulator layer located underlying the NMOS device. This is accomplished via formation of shallow trench openings in composite silicon nitride-silicon shapes, followed by lateral pull back of the silicon nitride shapes exposing portions of the top surface of the silicon shapes, followed by implantation of boron or nitrogen ions into portions of the insulator layer exposed in the STI openings and into portions of the insulator layer underlying exposed portions of the silicon shapes. A subsequent hydrogen anneal procedure finalizes the doped insulator layer which alleviates boron segregation from an overlying NMOS channel region.

  • Publication number: 20050275010
    Abstract: Nano-wires, preferably of less than 20 nm diameter, can be formed with minimized risk of narrowing and breaking that results from silicon atom migration during an annealing process step. This is accomplished by masking portion of the active layer where silicon atomer would otherwise agglomerate with a material such as silicon dioxide, silicon nitride, or other dielectric that eliminates or substantially reduces the silicon atom migration. Nano-wires, nanotubes, nano-rods, and other features can be formed and can optionally be incorporated into devices, such as by use as a channel region in a transistor device.
