Abstract:
1. An imaging module, comprising: a first resin board; a second resin board placed on or above the first resin board and having a first opening; a first electrically-conductive member electrically connecting the first resin board and the second resin board to each other; a printed circuit board placed on or above the second resin board and having a light-receiving opening; a second electrically-conductive member electrically connecting the second resin board and the printed circuit board to each other; an imaging semiconductor chip having a principal surface on which an imaging sensor for receiving light from outside the module is provided, the imaging semiconductor chip being mounted on a lower surface of the second board to cover the first opening with the principal surface of the imaging semiconductor chip facing upward; an optical member overlapping the imaging semiconductor chip when viewed from above and placed on an upper surface of the second resin board to cover the first opening, the optical member being smaller than the light-receiving opening when viewed from above; a semiconductor control chip having a principal surface on which a control device for controlling operation of the imaging sensor is provided; a parallel-plane member located between the second resin board and the printed circuit board, having a second opening surrounding the optical member. and including: a first resin base having a first through hole and having a uniform thickness; an adhesive layer formed on an upper surface of the first resin base; and a third electrically-conductive member buried in the first through hole and in the adhesive layer; a first sheet member located between the first resin board and the second resin board. having a third opening formed so as to accommodate the semiconductor control chip therein, and including a second resin base having a second through hole, first adhesive members provided on upper and lower surfaces of the second resin base and a first electrically-conductive member buried in the second through hole and in the first adhesive members: and a second sheet member located between the second resin board and the parallel-plane member, having a fourth opening formed so as to accommodate the optical member therein, and including a third resin base having a third through hole, second adhesive members provided on upper and lower surfaces of the third resin base, and a fourth electrically-conductive member buried in the third through hole and in the second adhesive members. wherein the third electrically-conductive member is at least a part of the second electrically-conductive member, and the fourth electrically-conductive member is at least part of the second electrically-conductive member.
