    摘要: 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 (15) and a P-channel transistor (16). The N-channel transistor (15) has a gate electrode (35) that has a central portion (28) and two adjacent gate extensions (49, 52). Likewise the P-channel transistor (16) has a gate electrode (35') which has a central portion (29) and two adjacent gate extensions (53, 54). The gate extensions (49, 52, 53, 54) allow the formation of graded channel regions underneath the gate electrodes (35, 35') and adjacent to the source (57, 59) and drain (58, 62) regions by offsetting an LDD or a single heavily doped source/drain implant from channel regions which are covered by the gate extensions (49, 52 53, 54).

    摘要: 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).
