    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.

    摘要: A strained-channel transistor structure with lattice-mismatched zone and fabrication method thereof. The transistor structure includes a substrate having a strained channel region, comprising a first semiconductor material with a first natural lattice constant, in a surface, a gate dielectric layer overlying the strained channel region, a gate electrode overlying the gate dielectric layer, and a source region and drain region oppositely adjacent to the strained channel region, with one or both of the source region and drain region comprising a lattice-mismatched zone comprising a second semiconductor material with a second natural lattice constant different from the first natural lattice constant.
