摘要 |
The present invention is directed to a method that comprises forming a plurality of transistors, each transistor having at least a gate electrode, and forming halo implant regions in the transistors while varying at least one of a halo implant angle, a masking layer height, and a lateral offset of a masking layer from the gate electrode of the transistors. The method further comprises determining electrical performance characteristics of at least some of the transistors where at least one of the halo implant angle, the masking layer height, and the lateral offset of a masking layer are different, and comparing the determined electrical performance characteristics of the transistors.
