    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: Methods and associated structures of forming a microelectronic device are described. Those methods may include amorphizing at least one contact area of a source/drain region of a transistor structure by implanting through at least one contact opening, forming a first layer of metal on the at least one contact area, forming a second layer of metal on the first layer of metal, selectively etching a portion of the second metal layer, annealing the at least one contact area to form at least one silicide, and removing the unreacted first metal layer and second metal layer from the transistor structure and forming a conductive material in the at least one contact opening.
