Abstract
A method includes forming a wafer assembly of a semiconductor wafer and a light transmissible optical wafer which are fixed to each other, cutting the wafer assembly at a spacer unit to individually divide the wafer assembly into a plurality of camera modules each comprising a sensor chip and a lens chip bonded to each other by a spacer, forming a light shieldable mask film to determine a lens aperture of each of plural lens units on the light transmissible optical wafer; forming a groove in the light transmissible optical wafer that reaches the spacer unit and filling the groove with a light shieldable resin to form a light shieldable resin layer; and cutting the light shieldable resin layer at a width less than the groove to individually divide the camera modules in each of which the light shieldable resin layer is provided at a side of the lens chip.
