Patent ID: 7208383

Claim:
A method for manufacturing a semiconductor component, comprising: providing a semiconductor material of a first conductivity type having a major surface; forming a gate structure on the major surface, wherein the gate structure has first and second sides and a top surface, and wherein the gate structure does not include spacers; implanting a dopant of a second conductivity type into the semiconductor material to form first and second doped extension regions, wherein the implant forming the first and second doped extension regions is limited to a single angled implant that makes an angle of less than 90 degrees with respect to a direction perpendicular to the major surface, and wherein the first doped extension region is adjacent the first side of the gate structure and extends under the gate structure, and the second doped extension region is laterally spaced apart from the second side of the gate structure without implanted dopant underlying the second side of the gate structure so as to form an asymmetric dopant profile; forming first and second spacers adjacent the first and second sides of the gate structure, respectively; and forming first and second doped regions in the semiconductor material, the first and second doped regions being respectively source and drain regions and being continuous with the first and second doped extension regions, the first doped region aligned to the first spacer and the second doped region aligned to the second spacer.
