Contact Image Sensors
Contact image sensors (CIS) can be used in a wide variety of applications such as counterfeit detectors, check readers, color scanners, digital copiers, mark readers, barcode readers, OCR, edge detectors, and positioning and optical encoding.
With silicon butting, contact image sensors can be combined together and housed to form a CIS module. One chip can be butted to another chip to form a long image sensor module.
The length of the module can be extended to A8, A6, A4, B4, A3, ... up to A0 size.
