ABSTRACT:
Semiconductor chips for use in a chip array assembly for scanning of hard-copy images include rows of photosensors, each row of photosensors having a polyimide filter layer for passing one primary color. In addition to the photosensors, a reflective area is provided on the chip, with filter portions provided on the reflective area. The filter portions are created at the same time as the filter layers placed on the photosensors. The filter layers disposed on the reflective area can be used as test sites for determining the light transmissivity of the filter layers on the photosensors.
