Abstract:
1. A structure, comprising: a dielectric layer on a semiconductor substrate; a cathode stack on a top surface of said dielectric layer, a sidewall of said cathode stack extending from a top surface of said cathode stack to said top surface of said dielectric layer; a continuous polysilicon layer, said polysilicon layer comprising a cathode region, an anode region, a link region between said cathode and anode regions and a transition region between said cathode region and said link region, said transition region proximate to said sidewall of said cathode stack, said sidewall of said cathode stack under said transition region, said cathode region on a top surface of said cathode stack, said link region on a top surface of said dielectric layer, both a first thickness of said cathode region and a second thickness of said link region greater than a third thickness of said transition region; and a metal silicide layer on a top surface of said polysilicon layer.
