摘要
An integrated circuit structure includes a semiconductor doped area (NWell) having a first conductivity type, and a layer (PSD) that overlies a portion of said doped area (NWell) and has a doping of an opposite second type of conductivity that is opposite from the first conductivity type of said doped area (NWell), and said layer (PSD) having a corner in cross-section, and the doping of said doped area (NWell) forming a junction beneath said layer (PSD) with the doping of said doped area (NWell) diluted in a vicinity below the corner of said layer (PSD). Other integrated circuits, substructures, devices, processes of manufacturing, and processes of testing are also disclosed.
