Abstract: A method of improving transistor carrier mobility by adjusting stress through recessing shallow trench isolation is presented. A trench is formed in a substrate. The trench is filled with a dielectric. A CMOS transistor is formed adjacent to the trench. A silicide layer is formed on the source/drain region. A recess is formed by etching the dielectric so that the surface of the dielectric is substantially lower than the surface of the substrate. Recessing the STI removes the compressive stress applied to the channel region by the STI material. A contact etch stop layer (CESL) is formed over the gate electrode, spacers, source/drain regions and the dielectric. The CESL applies a desired stress to the channel region. Trench liners are optionally formed to provide a stress to the channel region. A spacer can optionally be formed in the STI recess.

The second sacrificial layer in the first gate opening is removed, and then a first conductive layer is filled in the first gate opening as a gate of a MOS transistor of a first conductivity type. Then, the second sacrificial layer in the second gate opening is removed. A second conductive layer is filled in the second gate opening as a gate of a MOS transistor of a second conductivity type, and the first sacrificial layer is removed.

Abstract: Systems and methods are described for controlling critical dimension (CD) variation at the bottom of a tapered contact via on a semiconductor substrate. The invention monitors contact vias on a wafer to detect variations in CD at the top of the via in order to facilitate selective alteration of etching component ratios in an etching process, which permits adjustment of the slope of the tapered contact vias. In this manner, the invention compensates for top CD variations to maintain desired CD at the bottom of tapered vias within a target tolerance on subsequent wafers in a wafer fabrication environment.
