Abstract
A threshold adjusting semiconductor material, such as a silicon/germanium alloy, may be provided selectively for one type of transistors on the basis of enhanced deposition uniformity. For this purpose, the semiconductor alloy may be deposited on the active regions of any transistors and may subsequently be patterned on the basis of a highly controllable patterning regime. Consequently, threshold variability may be reduced.
