摘要： A photosensitive chip, such as used in a scanner or facsimile, defines a linear array of photosites, each photosite being covered with a filter formed from a cured translucent liquid. At the critical ends of the chip, between the end photosite in the array and the edge of the chip, there is provided a ridge which protrudes over the thickness of the filter. This ridge maintains the physical integrity of the filter.

摘要： A process for separating image sensor dies and the like from a wafer in which pairs of separation grooves separating each row of dies are formed in the active side of the wafer, with the tab between each groove pair being substantially equal to the width of the dicing blade, cutting a single bottom groove in the inactive side of the wafer opposite to and spanning each pair of separation grooves, and aligning the dicing blade with the midpoint of the wall of one groove in each pair of grooves so as to cut between the rows of dies. In a second embodiment, a two-pass separation process is enabled in which the tab between separation grooves is slightly larger than the width of the dicing blade, with the dicing blade first aligned with the midpoint of one separation groove to cut one row of dies from the wafer together with part of the tab, with the blade realigned with the midpoint of the other separate groove to cut a second row of dies and the remainder of the tab.

摘要： A wafer design and dicing technique for creating semiconductor chips from wafers. A succession of oxide layers are deposited in first and second regions of a surface of a silicon substrate. The regions are separated by a street having no oxide layers therein, and the successive oxide layers form a vertical wall with a surface normal to the surface of the silicon substrate. A shock-absorbent material is deposited in the street, forming a concave meniscus therein. The shock-absorbent material retards the trajectories of silicon particles set into motion when the wafer is diced into chips.

摘要： 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.

摘要： In a photosensitive chip suitable for full-color imaging, separate photosites on the chip correspond to different primary colors in an original image. Each primary-color photosite is filtered with a polyimide doped to a particular primary color. The red-filtering layer and the blue-filtering layer are left on the non-photosensitive portions of the main surface of the chip, and together serve as a non-reflective area which prevents stray reflections from the chip. The chip is further provided with a base layer of infrared-filtering polyimide.
