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.

摘要:
A zinc oxide film is formed on an electroconductive substrate by electrodeposition. The electrodeposition is performed by immersing an electroconductive substrate and an electrode in an aqueous solution containing nitrate ion and zinc ion, and supplying a current passing through a gap between the electroconductive substrate and the electrode while vibrating the electroconductive substrate to stably form a uniform zinc oxide film free from anomalous growth of a crystal on the electroconductive substrate. The zinc oxide film is excellent in adhesive properties with the electroconductive substrate and suitable for a light-confining layer of a photo-electricity generating device.
