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.

A method of a bulk tri-gate transistor having stained enhanced mobility and its method of fabrication. The present invention is a nonplanar transistor having a strained enhanced mobility and its method of fabrication. The transistor has a semiconductor body formed on a semiconductor substrate wherein the semiconductor body has a top surface on laterally opposite sidewalls. A semiconductor capping layer is formed on the top surface and on the sidewalls of the semiconductor body. A gate dielectric layer is formed on the semiconductor capping layer on the top surface of a semiconductor body and is formed on the capping layer on the sidewalls of the semiconductor body. A gate electrode having a pair of laterally opposite sidewalls is formed on and around the gate dielectric layer. A pair of source/drain regions are formed in the semiconductor body on opposite sides of the gate electrode.
