Abstract
Semiconductor chips, such as photosensor arrays for a full-page-width scanner or printhead chips for a full-page-width ink-jet printer, are mounted on a substrate to maintain reasonably consistent spacing among adjacent chips. To remove a defective chip from the array, the substrate is urged evenly against a work surface defining a convex bow. Alternately, back-cuts are provided along abutting edges of the chips, and the silicon around these back-cuts can be sawed away to space defective chips from neighboring good chips.
