Claim Text:
1. A semiconductor diode, comprising: a semiconductor substrate having a lightly doped region with a first conductivity type therein; a first heavily doped region with a second conductivity type opposite to the first conductivity type in the lightly doped region; a second heavily doped region with the first conductivity type in the lightly doped region and in direct physical contact with the first heavily doped region, wherein the first heavily doped region is adjacent to the second heavily doped region, and wherein a top portion of the first or second heavily doped region is in the lightly doped region; a first metal silicide layer on the semiconductor substrate and in direct contact with the first heavily doped region; and a second metal silicide layer on the semiconductor substrate and in direct contact with the second heavily doped region, wherein the second metal silicide layer is spaced apart from the first metal silicide layer.
