Direct contact-type image sensor unit

A new type of flip-chip mounting method and a new type of optical plate have been developed. In addition, a new type of multi-chip direct contact-type image sensor has been developed, using the above mounting method and optical plate, for graphic image scanners used in office equipment such as high-speed facsimiles, intelligent photo-copy equipment, and computers. Furthermore, a next-generation multi-chip direct contact-type image sensor is now being developed.
