Abstract:
1. A method of manufacturing an image sensor comprising: forming a stud bump on each electrode pad of the predetermined number of IC chips provided in a first substrate, the stud bump on each electrode pad including two or more bumps laminated together; carrying out indium plating with respect to a second substrate; transferring said plated indium to said second substrate to the distal end of each of said stud bump so that a plurality of thin film layers can be formed; connecting each of said thin film layers with the electrode of each of sensor elements so that a sensor element array having the plurality of said sensor elements arrayed like two-dimensional matrix is mounted to each of IC chips of said first substrate by flip chip mounting; and injecting an insulating resin between said first substrate and said sensor element array, and thereafter, hardening said insulating resin.
