    摘要: A compressive stress is applied to a channel region of a PFET by structure including a discrete dielectric stressor element that fully underlies the bottom surface of an active semiconductor region in which the source, drain and channel region of the PFET is disposed. In particular, the dielectric stressor element includes a region of collapsed oxide which fully contacts the bottom surface of the active semiconductor region such that it has an area coextensive with an area of the bottom surface. Bird's beak oxide regions at edges of the dielectric stressor element apply an upward force at edges of the dielectric stressor element to impart a compressive stress to the channel region of the PFET.

    摘要: A chip is provided which includes an active semiconductor region and a field effect transistor (“FET”) having a channel region, a source region and a drain region all disposed within the active semiconductor region. The FET has a longitudinal direction in a direction of a length of the channel region, and a transverse direction in a direction of a width of the channel region. A buried dielectric stressor element has a horizontally extending upper surface at a first depth below a major surface of a portion of the active semiconductor region, such as an east portion of the active semiconductor region. A surface dielectric stressor element is disposed laterally adjacent to the active semiconductor region at the major surface of the active semiconductor region. The surface dielectric stressor element extends from the major surface to a second depth not substantially greater than the first depth. The stresses applied by the buried and surface dielectric stressor elements cooperate together to apply a shear stress to the channel region of the FET.

    摘要: The present invention relates to a semiconductor-on-insulator (SOI) substrate having one or more device regions. Each device region comprises at least a base semiconductor substrate layer and a semiconductor device layer with a buried insulator layer located therebetween, while the semiconductor device layer is supported by one or more vertical insulating pillars. The vertical insulating pillars each preferably has a ledge extending between the base semiconductor substrate layer and the semiconductor device layer. The SOI substrates of the present invention can be readily formed from a precursor substrate structure with a “floating” semiconductor device layer that is spaced apart from the base semiconductor substrate layer by an air gap and is supported by one or more vertical insulating pillars. The air gap is preferably formed by selective removal of a sacrificial layer located between the base semiconductor substrate layer and the semiconductor device layer.
