Abstract:
1. A semiconductor device comprising: a semiconductor chip; first pads provided on a main surface of said semiconductor chip such that a light-receiving surface thereof is exposed; a light-receiving element portion provided on said main surface of said semiconductor chip such that a light-receiving surface thereof is exposed; a light-transmitting portion provided so as to cover the light-receiving surface of said light-receiving element portion for transmitting incoming light to said light-receiving element portion; an insulating film provided over said main surface of said semiconductor chip, the insulating film having a first region and a second region, the light-transmission portion being disposed on a surface of the first region, the second region surrounding said first pads so as to expose surface portions of said first pads, the first and second regions having substantially the same thickness; wiring patterns electrically connected to said first pads, the wiring patterns extending from said surface portions of said first pads and over said insulating film; post portions provided on said wiring patterns, a combination of the wiring patterns and the post portions thereon having substantially the same thickness as the light-transmitting portion; a sealing layer provided on said wiring patterns, on said insulating film, on a side surface of said light-transmitting portion, and on side surfaces of said post portions, such that an upper surface of said light-transmitting portion and top surfaces of said post portions are exposed, said sealing layer having cut side surfaces which are cut by a blade and which are substantially in the same plane of side surfaces of said semiconductor chip; and external terminals provided on the top surfaces of said post portions.
