Claim Text:
1. A PN junction comprising first and second areas of a semiconductor material, wherein one of said first and second areas comprises n-type doping and the other of said first and second areas comprises p-type doping, said n-type doping and said p-type doping having substantially similar doping densities, wherein said first area has one or more projections which at least partially overlap with said second area, so as to form at least one cross-over point and at least one counter-doped region, said at least one counter-doped region having a substantially lower net carrier density than non-overlapped regions of said first and second areas, said cross-over point being a point at which an edge of said first area crosses over an edge of said second area, and wherein said projections of said first area overlap said second area by a distance of at least 100 nm.
