Abstract:
1. A solid image-pickup device comprising: a semiconductor device having a plurality of light sensors located at a first side; through holes extending from a second side of said semiconductor device to the first side providing electrical communication between the light sensors and electrical connections at the second side of said semiconductor device; a flexible circuit substrate disposed adjacent to the second side of said semiconductor device; an insulating film covering inner side surfaces of the through holes; and an electrically conductive material fully filled in the through holes, wherein the electrically conductive material is in contact with lower surfaces of bonding pads located at the first side providing electrical communication to the light sensors and further wherein the electrically conductive material extends through holes in conductive pads at a side of said semiconductor device that is opposite the side at which the bonding pads are located, thereby electrically connecting the bonding pads and conductive pads, and wherein said flexible circuit substrate has the conductive pads formed thereon and said flexible circuit substrate has holes at locations corresponding to the through holes, the holes in the said flexible circuit substrate extending through the conductive pads and having a substantially larger diameter than the through holes, a portion of the electrically conductive material being over-filled from the openings of the through holes at the second side of said semiconductor device, the electrically conductive material being electrically connected with said flexible circuit substrate.
