Abstract
A silicon-on-insulator semiconductor device (40) having laterally-graded channel regions (23A, 24A) and a method of making the silicon-on-insulator semiconductor device (40). The silicon-on-insulator semiconductor device (40) has a gate structure (16) having sidewalls (19, 21) on a semiconductor layer (12). Lightly doped regions (26A, 27A) extend through an entire thickness of a portion of the semiconductor layer (12) under the sidewalls (19, 21). A laterally-graded channel region (23A) is formed below the gate structure (16) and abutting one (26A) of the lightly doped regions. A source (33) is formed in a first (26A) of the lightly doped regions and a drain region (34) is formed in a second (27A) of the lightly doped regions.
