ABSTRACT:
A multipixel light sensing semiconductor device contains in at least one pixel a lens presenting a convex surface and a lens supporting layer for directing light inwardly to a semiconductive light sensor. The lens supporting layer has a thickness exceeding that of the lens, and the lens is laterally confined on the lens supporting layer between at least two opposed pixel edges.
