Patent ID: 8796767

Claim:
A semiconductor device comprising: a substrate having a surface, the substrate including a first dopant material having a concentration from about 1×10 13 /cm 3 to about 1×10 17 /cm 3 ; at least two active regions formed proximate to the surface of the substrate, the at least two active regions each including a second dopant material; and a gate structure formed over the surface of the substrate between the at least two active regions, the gate structure including a doped polycrystalline layer and an oxide layer formed over the surface between the surface and the doped polycrystalline layer, the doped polycrystalline layer including the first dopant material having a concentration ranging from about 1×10 19 /cm 3 to about 1×10 21 /cm 3 , wherein the doped polycrystalline layer further comprises a first doped polycrystalline region including the second dopant material having a concentration ranging from about 1×10 19 /cm 3 to about 1×10 21 /cm 3 , a second doped polycrystalline region including the first dopant material having a concentration ranging from about 1×10 19 /cm 3 to about 1×10 21 /cm 3 , and a third doped polycrystalline region including the second dopant material having a concentration ranging from about 1×10 19 /cm 3 to about 1×10 21 /cm 3 , the first doped polycrystalline region and the third doped polycrystalline region comprise at least two separate and distinct regions disposed within an interior of the second doped polycrystalline region.
