Claim Text:
1. A method of forming a semiconductor device, the method comprising: forming a gate structure over an SOI substrate, said SOI substrate comprising a base semiconductor material, a buried insulation material positioned above said base semiconductor material and a semiconductor film positioned above said buried insulation layer, said gate structure having first and second opposing sides; performing at least one process operation to remove a portion of said semiconductor film and to remove a portion of said buried insulation layer located proximate said first opposing side of said gate structure so as to form a trench proximate said first opposing side without removing a portion of said semiconductor film or a portion of said buried insulation layer on said second opposing side; forming a first source and drain region in said trench on said first opposing side; and forming a second source and drain region on said semiconductor film on said second opposing side.
