Abstract:
In one exemplary embodiment of the invention, an asymmetric P-type field effect transistor includes: a source region coupled to a drain region via a channel; a gate structure overlying at least a portion of the channel; a halo implant disposed at least partially in the channel, where the halo implant is disposed closer to the source region than the drain region; and a body-tie coupled to the channel. In a further exemplary embodiment, the asymmetric P-type field effect transistor is operable to act as a symmetric P-type field effect transistor.
