A semiconductor substrate includes a matrix of photosites. Each photosite is delimited by an isolation trench including polycrystalline silicon. A peripheral zone extends directly around the matrix of photosites. The peripheral zone includes dummy photosites delimited by isolation trenches including...

Zusammenfassung:A semiconductor substrate includes a matrix of photosites. Each photosite is delimited by an isolation trench including polycrystalline silicon. A peripheral zone extends directly around the matrix of photosites. The peripheral zone includes dummy photosites delimited by isolation trenches including polycrystalline silicon. A density of polycrystalline silicon in the peripheral zone is between a density of polycrystalline silicon at an edge of the matrix of photosites and a density of polycrystalline silicon around the peripheral zone.
