Abstract
Insulated gate semiconductor device (10) and a method of manufacturing the insulated gate semiconductor device (10). The insulated gate semiconductor device (10) includes an N-channel transistor (55) and a P-channel transistor (60). The N-channel transistor (55) has a gate electrode (22') that has a central portion (22) and gate electrode extensions (41) adjacent to the central portion (22). Likewise the P-channel transistor (60) has a gate electrode (24') that has a central portion (24) and gate electrode extensions (42) adjacent to the central portion (24). The gate electrode extensions (41, 42) are formed by filling openings (34, 36) with a gate electrode material. The openings are used for the formation of graded channel regions underneath the gate electrode extensions (41, 42).
