Geometries for photosites in a photosensitive silicon chip

In a hard-copy scanner in which a set of photosensitive silicon chips are abutted to form a single page-width array of photosensors, the photosites at the critical ends of each chip are specially shaped to ensure an even spacing of all photosites along the array, taking into account imprecisions in...

Zusammenfassung:	In a hard-copy scanner in which a set of photosensitive silicon chips are abutted to form a single page-width array of photosensors, the photosites at the critical ends of each chip are specially shaped to ensure an even spacing of all photosites along the array, taking into account imprecisions in the dimensions of individual chips. The special shape of the end photosite is trapezoidal or a variation of trapezoidal.
