Abstract:
1. A semiconductor device manufacturing method, comprising: a first step of preparing a semiconductor substrate having a first face that includes a first region and a second region and a second face in opposition to the first face; a second step of forming an electronic circuit on the second face side of the semiconductor substrate; a third step of forming an optical fiber fastening groove in the second region of the first face of the semiconductor substrate, and then forming a through hole that passes from the first face to the second face in the first region of the first face of the semiconductor substrate; a fourth step of forming an insulating film on the second region of the first face and on a lateral face of the through hole, and then forming a wiring on the insulating film; a fifth step of connecting the electronic circuit and the wiring; and a sixth step of connecting an optical element to the wiring formed on the second region of the first face so that its optical axis is parallel to the optical fiber fastening groove.
