Abstract:
1. A semiconductor device, comprising: a gate stack in a gate of a field effect transistor, wherein the gate stack is positioned above a channel region of the field effect transistor and above a part of the field effect transistor outside the channel region; and a polysilicon layer above the gate stack in the gate of the field effect transistor, the polysilicon layer comprising a first doped portion above the channel region of the field effect transistor and a second doped portion above the part of the field effect transistor outside the channel region, wherein both the first and second doped portions are in contact with the gate stack, wherein the first doped portion is doped with a first dopant type and the second doped portion is doped with a second dopant type that is complementary to the first dopant type, and wherein the second doped portion is located a selected distance away from the channel region, the selected distance selected such that the second doped portion has little to no affect on the operation of the field effect transistor.
