Patent ID: 7691717

Claim:
A method for fabricating a resistor comprising: implanting into a polysilicon containing layer located over a substrate: at least one p dopant selected from the group consisting of a boron dopant and a boron difluoride dopant at a total p dopant dose from about 1e14 to about 1e16 dopant ions per square centimeter; and at least one n dopant consisting of a phosphorus dopant at a total n dopant dose from about 1e14 to about 1e16 dopant ions per square centimeter; and annealing the polysilicon containing layer to activate the p dopant and the n dopant wherein the implanting and the annealing provide the polysilicon containing layer with a sheet resistance from about 100 to about 5000 ohms per square, and a sheet resistance percentage standard deviation less than about 1.5%.
