    摘要: An integrated circuit includes a substrate, a first transistor, and a second transistor. The first transistor has a first gate dielectric portion located between a first gate electrode and the substrate. The first gate dielectric portion includes a first high-permittivity dielectric material and/or a second high-permittivity dielectric material. The first gate dielectric portion has a first equivalent silicon oxide thickness. The second transistor has a second gate dielectric portion located between a second gate electrode and the substrate. The second gate dielectric portion includes the first high-permittivity dielectric material and/or the second high-permittivity dielectric material. The second gate dielectric portion has a second equivalent silicon oxide thickness. The second equivalent silicon oxide thickness may be different than the first equivalent silicon oxide thickness.

    摘要: A transistor structure comprises a channel region overlying a substrate region. The substrate region comprises a first semiconductor material with a first lattice constant. The channel region comprises a second semiconductor material with a second lattice constant. The source and drain regions are oppositely adjacent the channel region and the top portion of the source and drain regions comprise the first semiconductor material. A gate dielectric layer overlies the channel region and a gate electrode overlies the gate dielectric layer.
