  • Patent number: 7663185
    Abstract: A fin-FET device and a method for fabrication thereof both employ a bulk semiconductor substrate. A fin and an adjoining trough are formed within the bulk semiconductor substrate. The trough is partially backfilled with a deposited dielectric layer to form an exposed fin region and an unexposed fin region. A gate dielectric layer is formed upon the exposed fin region and a gate electrode is formed upon the gate dielectric layer. By employing a bulk semiconductor substrate the fin-FET device is fabricated cost effectively.

  • Patent number: 7452778
    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.

  • Patent number: 7332777
    Abstract: In a method of manufacturing a semiconductor device, an initial structure is provided. The initial structure includes a substrate, a patterned silicon layer, and a covering layer. The substrate has a buried insulator layer formed thereon. The patterned silicon layer is formed on the buried insulator layer. The covering layer is formed on the patterned silicon layer. A first layer is formed on the initial structure. Part of the first layer is removed with an etching process, such that a sidewall portion of the patterned silicon layer is exposed and such that a remaining portion of the first layer remains at a corner where the patterned silicon layer interfaces with the buried insulator layer. An oxide liner is formed on the exposed sidewall portion. A recess may be formed in the buried insulator layer (prior to forming the first layer) and may extend partially beneath the patterned silicon layer.

  • Patent number: 7265425
    Abstract: A semiconductor device formed on a semiconductor substrate and a method of forming the same. In one embodiment, the semiconductor device includes a gate over the semiconductor substrate and a dielectric liner on a sidewall of the gate. The semiconductor device also includes an extension spacer adjacent and extending laterally beyond the dielectric liner along the semiconductor substrate. The semiconductor device further includes a source/drain located below an upper surface of the semiconductor substrate and adjacent a channel region under the gate. The source/drain extends under the dielectric liner and the extension spacer. The semiconductor device still further includes a silicide region over a portion of the source/drain and extending laterally beyond the extension spacer along the semiconductor substrate. Thus, the extension spacer is interposed between the dielectric liner and the silicide region located over a portion of the source/drain.

  • Patent number: 7205601
    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.
