Abstract:
1. A field effect transistor device comprising: an active area including a first semiconductor material of a first conductivity type; a channel region within the active area; a gate region overlaying the channel region; a first source/drain region and a second source/drain region embedded in the active area and spaced from each other by the channel region, the first source/drain region and the second source/drain region each include a second semiconductor material of a second conductivity type opposite of the first conductivity type; a well-tap region embedded in the active area and spaced from the first source/drain region by the channel region and the second source/drain region, the well-tap region comprising the second semiconductor material of the first conductivity type; and wherein the first source/drain region, the second source/drain region, and the well-tap region are epitaxial deposits.
