Method of creating a strained channel region in a transistor by deep implantation of strain-inducing species below the channel region

By incorporating a carbon species below the channel region of a P-channel transistor prior to the formation of the gate electrode structure, an efficient strain-inducing mechanism may provided, thereby enhancing performance of P-channel transistors. The position and size of the strain-inducing regio...

Zusammenfassung:By incorporating a carbon species below the channel region of a P-channel transistor prior to the formation of the gate electrode structure, an efficient strain-inducing mechanism may provided, thereby enhancing performance of P-channel transistors. The position and size of the strain-inducing region may be determined on the basis of an implantation mask and respective implantation parameters, thereby providing a high degree of compatibility with conventional techniques, since the strain-inducing region may be incorporated at an early manufacturing stage, directly to respective "large area" contact elements.
