    摘要: Isolated and bulk semiconductor devices formed on a same bulk substrate and methods to form such devices are described. For example, a semiconductor structure includes a first semiconductor device having a first semiconductor body disposed on a bulk substrate. The first semiconductor body has an uppermost surface with a first horizontal plane. The semiconductor structure also includes a second semiconductor device having a second semiconductor body disposed on an isolation pedestal. The isolation pedestal is disposed on the bulk substrate. The second semiconductor body has an uppermost surface with a second horizontal plane. The first and second horizontal planes are co-planar.

    摘要: A nanowire device having a plurality of internal spacers and a method for forming said internal spacers are disclosed. In an embodiment, a semiconductor device comprises a nanowire stack disposed above a substrate, the nanowire stack having a plurality of vertically-stacked nanowires, a gate structure wrapped around each of the plurality of nanowires, defining a channel region of the device, the gate structure having gate sidewalls, a pair of source/drain regions on opposite sides of the channel region; and an internal spacer on a portion of the gate sidewall between two adjacent nanowires, internal to the nanowire stack. In an embodiment, the internal spacers are formed by depositing spacer material in dimples etched adjacent to the channel region. In an embodiment, the dimples are etched through the channel region. In another embodiment, the dimples are etched through the source/drain region.

    摘要: A method of forming an isolated tri-gate semiconductor body comprises patterning a bulk substrate to form a fin structure, depositing an insulating material around the fin structure, recessing the insulating material to expose a portion of the fin structure that will be used for the tri-gate semiconductor body, depositing a nitride cap over the exposed portion of the fin structure to protect the exposed portion of the fin structure, and carrying out a thermal oxidation process to oxidize an unprotected portion of the fin structure below the nitride cap. The oxidized portion of the fin isolates the semiconductor body that is being protected by the nitride cap. The nitride cap may then be removed. The thermal oxidation process may comprise annealing the substrate at a temperature between around 900° C. and around 1100° C. for a time duration between around 0.5 hours and around 3 hours.
