Abstract:
1. A method for forming a vertically oriented p-i-n diode, the method comprising: forming a first rail-shaped conductor above a substrate; forming the p-i-n diode by: forming a silicide-forming metal region in contact with the top heavily doped n-type region of the p-i-n diode; forming a silicide, germanide, or silicide-germanide by reacting the silicide-forming metal region with the top heavily doped n-type region of the p-i-n diode; and annealing to crystallize the deposited semiconductor material, where some portion of the deposited semiconductor material was amorphous as deposited and is in contact with the silicide, germanide, or silicide-germanide before the annealing step.
