    摘要: Strained silicon is grown on a dielectric material in a trench in a silicon germanium layer at a channel region of a MOSFET after fabrication of other MOSFET elements using a removable dummy gate process to form an SOI MOSFET. The MOSFET is fabricated with the dummy gate in place, the dummy gate is removed, and a trench is formed in the channel region. Dielectric material is grown in the trench, and strained silicon is then grown from the silicon germanium trench sidewalls to form a strained silicon layer that extends across the dielectric material. The silicon germanium sidewalls impart strain to the strained silicon, and the presence of the dielectric material allows the strained silicon to be grown as a thin fully depleted layer. A replacement gate is then formed by damascene processing.

    摘要: An exemplary embodiment relates to a method of FinFET channel structure formation. The method can include providing a compound semiconductor layer above an insulating layer, providing a trench in the compound semiconductor layer, and providing a strained semiconductor layer above the compound semiconductor layer and within the trench. The method can also include removing the strained semiconductor layer from above the compound semiconductor layer, thereby leaving the strained semiconductor layer within the trench and removing the compound semiconductor layer to leave the strained semiconductor layer and form the fin-shaped channel region.
