ABSTRACT:
A method (10) of forming a transistor (100) includes treating (12) at least some of a semiconductor substrate (102) with carbon and then forming (18) a gate structure (114) over the semiconductor substrate. A channel region (122) is thereby being defined within the semiconductor substrate (102) below the gate structure (114). Source and drain regions (140, 142) are then formed (26) within the semiconductor substrate (102) on opposing sides of the channel (122) with a phosphorus dopant.
