    摘要: Optimal strain in the channel region of a PMOS transistor is provided by silicon alloy material in the junction regions of the device in a non-planar relationship with the surface of the substrate. The silicon alloy material, the dimensions of the silicon alloy material, as well as the non-planar relationship of the silicon alloy material with the surface of the substrate are selected so that the difference between the lattice spacing of the silicon alloy material and of the substrate causes strains in the silicon alloy material below the substrate surface, as well as above the substrate surface, to affect an optimal silicon alloy induced strain in the substrate channel. In addition, the non-planar relationship may be selected so that any strains caused by different lattice spaced layers formed over the silicon alloy material have a reduced effect on the strain in the channel region.

    摘要: A semiconductor device having high tensile stress. The semiconductor device comprises a substrate having a source region and a drain region. Each of the source region and the drain region includes a plurality of separated source sections and drain sections, respectively. A shallow trench isolation (STI) region is formed between two separated source sections of the source region and between two separated drain sections of the drain region. A gate stack is formed on the substrate. A tensile inducing layer is formed over the substrate. The tensile inducing layer covers the STI regions, the source region, the drain region, and the gate stack. The tensile inducing layer is an insulation capable of causing tensile stress in the substrate.
