Abstract
A wafer-scale linear image sensor chip (WLISC) is proposed with gapless pixel line and signal readout circuit segments. The WLISC converts pixel line image (PLI) of length Linto line image signal (LIS). The WLISC includes a linear array of sensor segments. Each sensor segment includes a gapless local pixel line segment (LPLS) of sensing elements. The LPLSconverts portion of the PLI into a raw image segment signal set (RISS). The LPLSset forms a gapless global pixel line (GPL) corresponding to PLI. The sensor segment also includes readout circuit segment (RCS) coupled to LPLSfor processing RISSinto a readout image segment signal set (ROSS). The RCShas a set of contact pads (CTP) for off-chip interconnection. Upon off-chip interconnection of the CTPset thus composing the ROSSset into LIS, the WLISC functions as a key part of a linear image sensor system of image length L.
