Patent number: 5266828Abstract: This invention relates to an image sensor with photo sensors (13). An object thereof is to simplify mounting operation of an image sensor chip (12) provided with the photo sensors (13). In order to accomplish this object, according to this invention, the photo sensors (13) and electrodes (15) are disposed on the underside of the image sensor chip (12). The image sensor chip (12) is bonded to the upper side of a transparent substrate (18) by means of a transparent photo-setting type insulating resin (16), so that the electrodes (15) come into contact with circuit conductor layers (17) disposed on the upper side of the transparent substrate (18). With the above-mentioned construction, since fine metal wire (75) by which the electrodes (15) and the circuit conductor layers (17) are connected to each other is not required, mounting operation can be simplified.Type: GrantFiled: May 18, 1992Date of Patent: November 30, 1993Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Tetsuro Nakamura, Takahiko Murata, Shinji Fujiwara
