    摘要: A structure and method for increasing the sensitivity of pixel sensors by eliminating a gap space formed between adjacent microlens structures in a pixel sensor array. Advantageously, exposure and flowing conditions are such that adjacent microlens structures touch (are webbed) at a horizontal cross-section, yet have a round lens shape in all directions. Particularly, exposure and flowing conditions are such that each touching microlens structure is formed to have a matched uniform radius of curvature at a horizontal cross-section and at a 45 degree cross-sections. To improve quality of mircrolens structure uniformity exhibited at all pixel locations including those near a pixel array edge or corner, a top anti-reflective coating layer is applied on top of a photoresist layer prior to the exposure and flowing steps.

    摘要: A method for manufacturing a stitched space in a semiconductor circuit implements a photolithographic process for printing one or more image fields on a wafer surface, each image field corresponding to a portion of a circuit or device and including a space that is to be stitched in adjacent image fields. The space to be stitched that is produced from an image field is overlapped onto the space to be stitched produced from the adjacent image field, however, the overlapped space from the adjacent image fields is intentionally misaligned. The stitched space is then subject to the double light exposure dose to print the stitched space, with the result that an overlay tolerance of the stitched space is improved.

    摘要: A method and system for determining overlay tolerances. The method comprises the steps of exposing wafers at different critical dimensions (preferably, above, below, and at optimum image size); and varying the overlay across each wafer, preferably by intentionally increasing the magnification. Functional yield data are used to determine the overlay tolerance for each of the image sizes. The present invention, thus, studies the interaction of image size and feature misalignment. Prior to this invention, the only way to attain this information was to process a large number of lots and create a trend of image size and alignment vs. yield. The present invention solves the problem by determining the overlay tolerance based on yield data from a single lot. The design can then be altered or the overlay limit can be tightened (or relaxed) based on failure analysis of the regions/features that are most sensitive to misalignment.

    摘要: Disclosed are embodiments of a transistor (e.g., bipolar junction transistor (BJT) or a heterojunction bipolar transistor (HBT)) and a method of forming the transistor with a collector region having a protected upper edge portion for reduced base-collector junction capacitance Cbc. In the embodiments, a collector region is positioned laterally adjacent to a trench isolation region within a substrate. Mask layer(s) cover the trench isolation region and further extend laterally onto the edge portion of the collector region. A first section of an intrinsic base layer is positioned above a center portion of the collector region and a second section of the intrinsic base layer is positioned above the mask layer(s). During processing these mask layer(s) prevent divot formation in the upper corner of the trench isolation region at the isolation region-collector region interface and further limit dopant diffusion from a subsequently formed raised extrinsic base layer into the collector region.
