    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.

    摘要: A strained silicon MOSFET employs a high thermal conductivity insulating material in the trench isolations to dissipate thermal energy generated in the MOSFET and to avoid self-heating caused by the poor thermal conductivity of an underlying silicon germanium layer. The high thermal conductivity material is preferably silicon carbide, and the isolations preferably extend through the silicon germanium layer to contact an underlying silicon layer so as to conduct thermal energy from the active region to the silicon layer.

    摘要: According to one exemplary embodiment, a FET which is situated over a substrate, comprises a channel situated in the substrate. The FET further comprises a first gate dielectric situated over the channel, where the first gate dielectric has a first coefficient of thermal expansion. The FET further comprises a first gate electrode situated over the first gate dielectric, where the first gate electrode has a second coefficient of thermal expansion, and where the second coefficient of thermal expansion is different than the first coefficient of thermal expansion so as to cause an increase in carrier mobility in the FET. The second coefficient of thermal expansion may be greater that the first coefficient of thermal expansion, for example. The increase in carrier mobility may be caused by, for example, a tensile strain created in the channel.
