Method of forming an image sensor with large radius micro-lenses

摘要

A solid state image sensor having micro-lenses connected to each other by filling separations between trapezoidal separated sections of a protection layer with photoresist and a manufacturing method thereof comprises trapezoidal separated sections of the protection layer which is formed on a predetermined lower layer of a semiconductor substrate and convex micro-lenses having a predetermined radius of curvature that are connected to each other by filling the separations between the separated sections of the protection layer with photoresist.
