Abstract:
1. A wafer-scale linear image sensor chip (WLISC) with a gapless pixel line and signal readout circuit segments for, expressed in an X-Y-Z Cartesian coordinate system with its pixel line along the X-direction and principal chip surface lying in the X-Y plane, photoelectrically converting a pixel line image (PLI) of image length L PL oriented along the X-direction into a corresponding line image signal (LIS), the WLISC comprises an X-direction linear array of contiguous sensor segments SS 1 , SS 2 , . . . , SS j , . . . , SS M (M>1) spaced at a scribe pitch (SCP), wherein each SS j further comprises: a) a gapless local pixel line segment (LPLS b) a readout circuit segment (RCS the WLISC further comprises two dicing margins DCM 1 and DCM M located respectively contiguous to SS 1 and SS M ; thus upon a pre-determined configuration of off-chip interconnection of the contact pad set (CTP 1 , . . . CTP M ) so as to compose the (ROSS 1 , . . . , ROSS M ) into the LIS, the WLISC functions as a key part of a linear image sensor system of image length L PL .
