Abstract:
1. A camera module manufacturing method, comprising steps of: preparing an image sensor wafer comprising a plurality of image sensor chips, wherein a photoelectric conversion element is disposed on one surface of each of the plurality of the image sensors and external connection terminals are disposed on another surface of each of the plurality of image sensors; preparing a lens array formed by disposing a plurality of lenses corresponding to the plurality of image sensor chips; bonding the lens array to the one surface of the image sensor wafer on which photoelectric conversion elements are disposed; fixing the image sensor wafer via the another surface of the image sensor wafer on a supporting member having grooves on a surface on which the image sensor wafer is fixed to correspond with dividing portions of the image sensor wafer; dividing the image sensor wafer into individual camera modules by forming grooves on the image sensor wafer; forming a light shielding layer on side surfaces of each lens to be separated from each other by supplying a non-transparent material in a liquid state to the grooves formed on the image sensor wafer; and bringing out the individual camera modules from the supporting member; wherein the grooves of the supporting member absorb an excessive non-transparent material in the liquid state.
