Abstract:
An image sensor comprising:an insulating substrate board;an array of a plurality of blocks on said substrate board, said blocks of said array each including a plurality of photodiodes, a corresponding number of blocking diodes connected respectively in series and opposite polarity to said photodiodes;a common electrode for said number of said blocking diodes for each of said blocks;a matrix wiring interconnecting ones of the photodiodes in the same relative positions within respective ones of said blocks;a transparent interlayer insulating film covering said photodiodes and said blocking diodes formed on said insulating substrate board;said transparent interlayer insulating film having a contact hole and a coupling electrode passing through said contact hole connecting each of said photodiodes to the corresponding one of said blocking diodes in series and opposite polarity; andsaid insulating substrate board being a glass substrate having a thickness of 0.3 to 0.7 mm and a width in the subordinate scanning direction of 1.0 to 2.0 mm, and a ratio of a length in the main scanning direction to the width in the subordinate scanning direction of said glass substrate being not less than about 50 and a ratio of the thickness of said glass substrate to the width in the subordinate scanning direction being not more than 0.7.
