Paper Abstract

Recent development ofG4 fax and scanner requires a high speed, high resolution, and high contrast second generation image sensor. This paper describes a silicon butting Contact Image Sensor (CIS) module which has been developed and produced to solve the problems encountered by using CCD image sensors. Due to the flexibility ofthe design, the CIS module can be made for the A6, A4 ,B4 or other paper sizes. This device can be operated at high speed (2 MHz or higher), high dynamic range (1000: 1) and high resolution (400DPI). By adding alayer ofcolor filter on top of the photosensor, it is also applicable for the color G4 facsimile and color scanner.
