Abstract
A method and apparatus for forming a junctionless antifuse semiconductor structure comprises forming an antifuse in non-active areas of a semiconductor wafer. In one embodiment, the antifuse is formed over a polysilicon layer, which is coupled to a field oxide layer. In a further embodiment, the polysilicon layer comprises a bottom conductor layer in the antifuse. In another embodiment, a refractory metal silicide layer is formed between the polysilicon layer and the antifuse. In yet a further embodiment, the refractory metal silicide layer comprises the bottom conductor layer in the antifuse.
