摘要： The present invention relates to electro optical devices with a reduced filter thinning on the edge pixels and a method for reducing the thinning of filter layers on the pixels closest to the edge of an electro optical device such as a photosensitive chip, as would be used, for example, in a full-color digital copier or scanner. A semiconductor wafer includes a main surface defining a plurality of chip areas and tab regions separated by grooves, wherein the chip areas include inner photosites, outer photosites and bonding pads. A plurality of dams are deposited over the main surface in the tab regions, and a clear layer is deposited over the main surface exclusive of the bonding pads. Alternatively, a clear layer is deposited over the main surface exclusive of the bonding pads, and a plurality of tabs is then deposited in the tab regions on the main surface. A first primary color filter layer is deposited over at least first inner photosite and first outer photosite, and the first primary color filter layer transmits a primary color.

摘要： An architecture and manufacturing method for photosensitive chips, such as used in office equipment and digital cameras, involves creating grooves between chip areas in a wafer, and then placing a light-transmissive planar layer over the main surface of the wafer. The planar layer, which may be acrylic-based, creates a substantially planar surface over both the photosites in the chip areas and the grooves. The planar layer in turn supports one or more light-transmissive filtering layers. The arrangement avoids damage to the filtering layers when the wafer is diced along the grooves.

摘要： The present disclosure relates that by modifying chip die dicing methodology to a U-groove profile from a V-groove profile by modifying the second etch step to be a dry etch instead of a wet etch results in a direct cost savings by eliminating a more expensive process step, as well as the need for stripping the developed photoresist layer. Furthermore, going to a U-groove profile accomplishes additional indirect and greater cost savings resulting from increased process throughput, improved yield, and reduced metal layer defects.

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 photosensitive imaging device for recording images across the entire visible spectrum includes a set of photosensors which have a peak response around the orange part of the spectrum, about 600 nm. The peak response is obtained by combining responses of, in one case, photosensors associated with a filter which admits red or infrared wavelengths and longer and photosensors associated with a filter which admits orange wavelengths and longer. In another case, the photosensor is structured to attenuate longer wavelengths, which, in combination with a filter which admits orange and longer wavelengths, can simulate a peak behavior around the orange part of the spectrum.
