Abstract
A diode device may be provided, including a semiconductor substrate including a well region arranged therein, a first doped region and a second doped region arranged within the well region, a first contact region arranged within the first doped region, and an isolation structure arranged within the first doped region, where an oxide layer may line a surface of the isolation structure. The first doped region and the first contact region may have a first conductivity type, and the well region and the second doped region may have a second conductivity type different from the first conductivity type. A doping concentration of the first contact region may be higher than a doping concentration of the first doped region, and a part of the first doped region may be arranged between the first contact region and the well region.
