Abstract:
1. A method for forming a transistor, the method comprising the steps of: providing a semiconductor substrate; patterning the semiconductor substrate to provide a first body edge; providing a first gate structure of a first fermi level adjacent said first body edge; patterning the semiconductor substrate to provide a second body edge, said first and second body edges of the semiconductor substrate defining a transistor body; providing a second gate structure of a second fermi level adjacent said second body edge; and forming a substantially uniform dopant concentration density throughout the transistor body, wherein the step of forming a substantially uniform dopant concentration density throughout the transistor body comprises performing a plurality of non-perpendicular angled implants into the body, wherein said performing the plurality of non-perpendicular angled implants into the body comprises performing a first non-perpendicular angled implant when the first body edge is exposed and performing a second non-perpendicular angled implant when the second body edge is exposed, wherein the first and second non-perpendicular angled implants are not performed simultaneously.
