Claim Text:
1. A diode, comprising: a first doped region doped only with a first dopant; a second doped region doped only with a second dopant, the second dopant having an opposite polarity of the first dopant; a contiguous, non-doped region separating the first doped region from the second doped region, wherein the non-doped region directly contacts a sidewall of the first doped region and the non-doped region directly contacts a sidewall of the second doped region, and substantially no lightly doped region lies between the second doped region and the first doped region; a first salicide portion disposed on the first doped region, the first salicide portion having a first sidewall surface in direct contact with the sidewall of the first doped region that extends to a surface of the non-doped region, a second sidewall surface in contact with a first shallow trench isolation region and an adjacent surface in direct contact with the first doped region, the first salicide portion defined by a salicide block mask positioned between the first doped region and the second doped region; and a second salicide portion disposed on the second doped region, the second salicide portion having a first sidewall surface in direct contact with the sidewall of the second doped region that extends to the surface of the non-doped region, a second sidewall surface in direct contact with a second shallow trench isolation region and an adjacent surface in contact with the second doped region, the second salicide portion defined by the salicide block mask.
