Abstract
A linear image sensor integrated circuit has a semiconductor substrate having a pixel region and a scribe region adjacent to the pixel region. A diffusion layer is disposed in the pixel region of the semiconductor substrate. A PN junction is formed between the semiconductor substrate and the diffusion layer for receiving light. A passivation film covers the PN junction and is disposed over a surface of the semiconductor substrate except for a portion of the surface thereof in the scribe region.
