Abstract: The techniques and technologies described herein relate to the automatic creation of photoresist masks for stress liners used with semiconductor based transistor devices. The stress liner masks are generated with automated design tools that leverage layout data corresponding to features, devices, and structures on the wafer. A resulting stress liner mask (and wafers fabricated using the stress liner mask) defines a stress liner coverage area that extends beyond the boundary of the transistor area and into a stress insensitive area of the wafer. The extended stress liner further enhances performance of the respective transistor by providing additional compressive/tensile stress.

Abstract: A test structure includes first and second pluralities of transistors. The first plurality of transistors includes gate electrodes of a first length. The second plurality of transistors includes gate electrodes of a second length different than the first length. A channel area of the transistors in the first plurality is substantially equal to a channel area of the transistors in the second plurality. A method for using the test structure includes measuring a performance metric of the first and second pluralities of transistors. Variation in the performance metric associated with the first plurality of transistors is compared to variation in the performance metric associated with the second plurality of transistors to identify a random length variation component associated with the first plurality of transistors.

Abstract: Ultra narrow and thin polycrystalline silicon gate electrodes are formed by patterning a polysilicon gate precursor, reducing its width and height by selectively oxidizing its upper and side surfaces, and then removing the oxidized surfaces. Embodiments include patterning the polysilicon gate precursor with an oxide layer thereunder, ion implanting to form deep source/drain regions, forming a nitride layer on the substrate surface on each side of the polysilicon gate precursor, thermally oxidizing the upper and side surfaces of the polysilicon gate precursor thereby consuming silicon, and then removing the oxidized upper and side surfaces leaving a polysilicon gate electrode with a reduced width and a reduced height. Subsequent processing includes forming shallow source/drain extensions, forming dielectric sidewall spacers on the polysilicon gate electrode and then forming metal silicide layers on the upper surface of the polysilicon gate electrode and over the source/drain regions.
