Abstract
Within a method for fabricating a field effect transistor (FET) device there is provided a series of ion implant methods which provide the field effect transistor (FET) device with both: (1) a source region asymmetrically doped with respect to a drain region; and (2) an asymmetrically doped channel region. The field effect transistor (FET) device is fabricated with enhanced performance.
