Abstract: PROBLEM TO BE SOLVED: To provide a method which can cut an edge part of a die very nearby an active element on the die, never damages the active element, and dices the die from a semiconductor wafer. SOLUTION: The present disclosure that by modifying chip die dicing methodology to a U-groove profile 300 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, using of a U-groove profile 300 accomplishes additional indirect and greater cost savings resulting from increased process throughput, improved yield, and reduced metal layer defects.

Abstract: PROBLEM TO BE SOLVED: To provide an improved low-cost spectrophotometer suitable for online color printing color control system. SOLUTION: An image forming chip 14 usually forms only a part of a document image forming bar having three rows and three colors used for a scanner, and has at least three different color filters having three rows. A plurality of photo-site chips D12C, D12D, and D12E are corrected to provide a photo-site D12F having no filter. The spectrophotometer has a considerably decreased number of different LEDs or other spectral illumination sources. One of the LEDs and the illumination sources may be white light. The spectrophotometer transmits a large number of spectral data outputs from photo-sites having different filters which are simultaneously illuminated with reflected light from color testing target areas which are sequentially illuminated with the restricted number of LEDs, provides information on broad-band spectra, and enables color control.

Abstract: PROBLEM TO BE SOLVED: To select a scanning time reduction priority mode or a depth-of-focus priority mode of a bound book original by selectively placing plural gradient index lens arrays of different depths of focus at the optical conjugate relation positions set between a copy image support member and an optical sensor array. SOLUTION: An optical device 23 includes 1st and 2nd gradient index lens arrays 100 and 101, an optical sensor array 24, etc. and performs reciprocating scanning under a transparent platen 20 where an image support member such as a document or a book, etc., is placed. The arrays 100 and 101 have the depths of focus 1.2mm and 2.6mm respectively, and one of both arrays 100 and 101 is moved to an optical path set between the image support member and the array 24 by a positioning mechanism of an RIS selector 48. When the image support member is a document, the high radiation efficiency is selected based on a small depth of focus. Meanwhile, a large depth of focus is selected for a bound book serving as the image support member, so that the copying surface of the book does not go out of focus.

Abstract: PROBLEM TO BE SOLVED: To cancel possibility for an area between a final photodetector in the linear array of photodetectors and the edge of a photodetector chip of a CMOS base to have the generation source of unintended charges to affect the final photodetector. SOLUTION: Concerning a photoelectric chip 10 partitioning a main side and an edge 22 of the main side, this photoelectric chip is provided with a photodetector 14 blocked on the main side so as to block the surrounding, a protecting loop 80 provided with a diffusion layer and at least partially arranged between the photodetector 14 and the edge 22, and a light shield area 60 arranged between the photodetector 14 and the edge 22. The protecting loop 80 formed into biased diffusion area prevents the leakage of unintended charges from edge area to terminal photodetector.

Abstract: PROBLEM TO BE SOLVED: To enable a circular P layer to operate as an electric charge collector and at the same time minimize the entire capacitance of a photodiode by allowing a polysilicon layer to essentially cover a gap and to be spread onto one portion of an exposure region and onto one portion of an oxide layer immediately outside the gap. SOLUTION: A gap 14 that nearly follows the entire shape of a polysilicon layer 12 is provided in a field oxide 10. More specifically, although the polysilicon layer 12 is spread around the partial assembly of a region where a contour is determined by the field oxide 10, as a whole, the gap 14 is located directly below the polysilicon layer 12. In this case, one portion of the polysilicon layer 12 spreads exceeding the edge of the gap 14 and partially overlaps with one portion of the field oxide 10 at both sides of the gap 14. Also, a relatively thin, for example approximately 180 Å, protection layer (a gate oxide 15) of the field oxide is placed between the gap 14 and the polysilicon layer 12.

Abstract: PROBLEM TO BE SOLVED: To provide an illuminating apparatus used to illuminate hard copy documents for digital recording such as in facsimile machines and digital copying machines.
SOLUTION: An optical element 10 comprises a light-transmissive material of a predetermined refractive index and has a first main surface 12, a second main surface 14, an exit surface 16 and a back structure 18. The back structure 18 has a plurality of small planar surfaces, each interspaced with discontinuity surfaces 52 and forming an arc symmetrical relative to a center line of the optical element. In at least the first main surface 12, a cavity 60 is formed, light L emanating from a light source 20 disposed in the cavity 60 is reflected by each small planar surface and is directed so as to exit substantially perpendicular to the exit surface 16. The overall desired effect is substantially even distribution of light through the entire area of exit surface 16.

Abstract: PROBLEM TO BE SOLVED: To provide a photosensitive imaging device, equipped with at least a set to photosensors having high sensitivity especially at the orange (about 600 nm) region of a visible spectrum. SOLUTION: A raster input scanner 102, which is a photosensitive imaging device for recoding images across the entire visible spectrum, is provided with a set of photosensors which have a peak response around the orange region (about 600 nm) of the spectrum. This peak response is obtained by combining the responses of photosensors associated with a filter, which admits red or infrared wavelengths the longer and the responses of photosensors associated with a filter which admits orange wavelengths and longer. In another cases, the photosensor is structured to attenuate longer wavelengths, and by combining it with a filter, which admits orange and longer wavelengths, a peak behavior around the orange part of the spectrum can be simulated.
