Abstract
A photosensitive element includes a semiconductor substrate, a light sensitive region formed in the semiconductor substrate, an inactive region at least partly surrounding the light sensitive region, and a protective layer having an opening leaving the light sensitive region uncovered by the protective layer. The protective layer is an anti-reflective coating having in at least a part of a spectral range between 300 nm and 1200 nm a reflectivity of less than 10% and a transmittance of less than 0.1%.
