Abstract:
1. A method for forming a non-volatile memory cell, the method comprising: forming a metal-insulator-metal (MIM) antifuse stack including: forming a contiguous p-i-n diode above the MIM antifuse stack, the contiguous p-i-n diode comprising deposited semiconductor material; forming a layer of a silicide, silicide-germanide, or germanide in contact with the deposited semiconductor material at a temperature lower than a temperature required to crystallize silicon or germanium; and after forming the silicide, silicide-germanide, or germanide layer, crystallizing the deposited semiconductor material in contact with the layer of silicide, silicide-germanide, or germanide; wherein the memory cell comprises the contiguous p-i-n diode and the MIM antifuse stack.
