Abstract:
A method for arranging reflective patterns for a liquid display (LCD) device. A substrate having at least one first pixel region and one second pixel region is provided, in which the first and second pixel regions have a reflector thereon, respectively, and the first pixel region is adjacent to the second pixel region. A first pattern is formed on the reflector on the first pixel region. A second pattern is formed on the reflector on the second pixel region, in which the second pattern is formed by dividing the first pattern into at least two pattern regions according to a predetermined direction and rearranging the pattern regions.
Abstract:
A method of fabricating a phase shift mask (PSM) is described. A patterned photoresist layer is formed on an opaque layer over a transparent plate. A thin mask layer is formed on the sidewalls of the patterned photoresist layer. The exposed opaque layer and transparent plate thereunder are then removed while using the patterned photoresist layer and mask layer as a mask. A phase shift opening is formed in the transparent plate, and thereby a phase shift layer is formed at the place where the phase shift opening is located. The patterned photoresist layer and the opaque layer thereunder are then removed to expose the transparent plate. The opaque layer under the mask layer can precisely self-align the phase shift layer to prevent alignment deviation caused by multiple lithography processes. The precision of the phase shift mask can be increased, and mask manufacture cost can be lowered.
Abstract:
A digital video acquisition system including a plurality of image processors (30A; 30B) is disclosed. A CCD imager (22) presents video image data on a bus (video_in) in the form of digital video data, arranged in a sequence of frames. A master image processor (30A) captures and encodes a first group of frames, and instructs a slave image processor (30B) to capture and encode a second group of frames presented by the CCD imager (22) before the encoding of the first group of frames is completed by the master image processor. The master image processor (30A) completes its encoding, and is then available to capture and encode another group of frames in the sequence. Video frames that are encoded by the slave image processor (30B) are transferred to the master image processor (30A), which sequences and stores the transferred encoded frames and also those frames that it encodes in a memory (36A; 38). The parameters of the encoding operation can be dynamically adjusted, for example in response to the nature of the video sequences being captured.
Abstract:
A method for managing image processing data buffers for processes having overlap input data between iterations includes loading a data buffer with an initial input data array and performing an image data array operation on the input data array. The method repeats the following steps for plural iterations including loading the data buffer with new input data forming a new input data array for a next iteration and performing the input data array operation on the new input data array. The overlap data consists of pixels at an end of each scan line. Loading new input data includes loading pixels following the overlap data for each scan line.
Abstract:
A method of forming a feature pattern in a photosensitive layer includes forming the photosensitive layer on a substrate, providing a first mask having a first opaque area thereon, and performing a first exposure process with a first dose to form a first unexposed image in the photosensitive layer. The method further includes performing a second exposure process with a second dose to expose sidewalls of the first unexposed image so that the sidewalls of the first unexposed image receive at least a portion of the second dose thus forming a second unexposed image in the photosensitive layer, and developing the photosensitive layer with a developing process to form the feature pattern and to create features having smaller widths than those which would result in developing the photosensitive layer of the first unexposed image.
Abstract:
A method of forming holes in a layer through a cross-shape image exposure. The method includes removing a section from each corner of the rectangular patterns on a photomask to form cross-shape patterns so that circular or elliptical contact holes are formed on a photoresist layer after photo-exposure and development. Optical image contrast between contacts is increased by the cross-shape patterns on the photomask.
Abstract:
An elongated shut apparatus includes a primary plate and a follower plate with the inner sides thereof facing to each other. Both the primary and the follower plate are made of soft high molecular material and have a concave shaped cross section with a thick central part getting thinner toward two lateral ends thereof.
Abstract:
A stringer block is formed on the interface between a HDP silicon oxide layer and a silicon substrate. During an etching process for defining the profile of a floating gate, the stringer block functions to expose a bottom corner stringer. Following that, a polysilicon etching process effectively removes the bottom corner stringer. As a result, a stringerless flash memory cell is formed to prevent leakage currents, resulting from the bottom corner stringer, and improve both the reliability and data retention ability of the device.
Abstract:
An inkjet pen including an ink reservoir for storing ink and providing ink for jetting. A port, located on top of the ink reservoir, fluid-communicated with the ambient air, is used for adjusting the air pressure inside the reservoir. A valve, operated by a spring or a resilient element, normally seals the port, while occasionally opening the port to introduce air into the reservoir when the ink level is low and the underpressure rises. In other embodiments, an elastic bag is included in the reservoir that has an opening communicated with the ambient air through a second port formed on top of the reservoir. The elastic bag expands in response to the increasing underpressure generated in the reservoir when ink is being used. The bag expansion actuates the opening of the valve so as to regulate the underpressure.
Abstract:
A method of code programming a mask read only memory (ROM) is disclosed. According to the method, a first photoresist layer is formed over word lines and a gate oxide layer of a substrate already having implanted bit lines. The first photoresist layer is patterned to develop pre-code openings over all of the memory cells, which correspond to intersecting word and bit lines. The first photoresist layer is then hardened using either a treatment implant or a treatment plasma. Subsequently, a second photoresist layer is formed over the first photoresist layer and patterned to develop real-code openings over memory cells which are actually to be coded with a logic “0” value. Each memory cell to be coded is then implanted with implants passing through the pre-code openings and the real code openings and into the memory cell.
