20120163709AUTOMATED IDENTIFICATION OF IMAGE OUTLIERS - Outlier images—those images that differ substantially from other images in a set—can be automatically identified. One or more penalty values can be assigned to each image that quantifies how different that image is from others in the set. A threshold can be determined based on the set of penalty values. Each image whose penalty values are above the threshold is an outlier image. The penalty values can be the sum of per-pixel penalty values multiplied by the number of pixels with nonzero penalty values. A per-pixel penalty value can be the difference between a color value for that pixel and a predetermined range of color values, based on corresponding pixels in other images. The per-pixel penalty value can be determined for each component color and then optionally summed together. The threshold penalty values can be adjusted to provide for greater, or less, sensitivity to differences among the images.06-28-2012

20140246676BIPOLAR DEVICE HAVING A MONOCRYSTALLINE SEMICONDUCTOR INTRINSIC BASE TO EXTRINSIC BASE LINK-UP REGION - A bipolar device with an entirely monocrystalline intrinsic base to extrinsic base link-up region. To form the device, a first extrinsic base layer, which is amorphous or polycrystalline, is deposited such that it contacts an edge portion of a monocrystalline section of an intrinsic base layer through an opening in a dielectric layer. A second extrinsic base layer is deposited on the first. An anneal is performed, either before or after deposition of the second extrinsic base layer, so that the extrinsic base layers are monocrystalline. An opening is formed through the extrinsic base layers to a dielectric landing pad aligned above a center portion of the monocrystalline section of the intrinsic base layer. The dielectric landing pad is removed and a semiconductor layer is grown epitaxially on exposed monocrystalline surfaces of the extrinsic and intrinsic base layers, thereby forming the entirely monocrystalline intrinsic base to extrinsic base link-up region.09-04-2014

20140353725SEMICONDUCTOR DEVICE AND METHOD OF FORMING THE DEVICE BY FORMING MONOCRYSTALLINE SEMICONDUCTOR LAYERS ON A DIELECTRIC LAYER OVER ISOLATION REGIONS - Disclosed are devices and methods of forming the devices wherein pair(s) of first openings are formed through a dielectric layer and a first semiconductor layer into a substrate and, within the substrate, the first openings of each pair are expanded laterally and merged to form a corresponding trench. Dielectric material is deposited, filling the upper portions of the first openings and creating trench isolation region(s). A second semiconductor layer is deposited and second opening(s) are formed through the second semiconductor and dielectric layers, exposing monocrystalline portion(s) of the first semiconductor layer between the each pair of first openings. A third semiconductor layer is epitaxially deposited with a polycrystalline section on the second semiconductor layer and monocrystalline section(s) on the exposed monocrystalline portion(s) of the first semiconductor layer. A crystallization anneal is performed and a device (e.g., a bipolar device) is formed incorporating the resulting monocrystalline second and third semiconductor layers.12-04-2014
