摘要： A pixel structure for a flat panel detector is constructed in which the diode silicon and the FET silicon are simultaneously etched to form isolated structures (array photodiodes, I/O elements, and so on) in which the edges or perimeters of the diode silicon features are self-aligned to the underlying FET SI features. The full, as-deposited, thickness of the FET gate dielectric and (at least) part of the FET silicon layer remains underneath the diode silicon across the entirety of the flat panel detector.

摘要： A solid-state imager with back-side irradiation. The present invention provides a solid-state imager that includes a substantially radiation transparent substrate adapted to receive incident radiation. The radiation travels through the substrate and a pixelated array of photosensitive elements to a scintillator material, which absorbs the radiation. The pixelated array of photosensitive elements receives light photons and measures the amount of light generated by radiation interactions with the scintillator material. With this imager, there is less spreading and blurring and thus a better quality image. In another embodiment, there is a substantially transparent material disposed between the pixelated array of photosensitive elements and the scintillator material. The substantially transparent material absorbs and substantially blocks electrons from entering the active regions of the pixelated array of photosensitive elements. This enables the imager to perform for a longer period of time according to its specifications.

摘要： A method for monitoring the quality of a manufacturing process for making detector panels that have a plurality of pixels in a two-dimensional array includes, in each detector panel, manufacturing a set of baseline pixels and a set of test pixels. Each test pixel has an electrical component having a geometric dimension varied by an amount sufficient to introduce a measurable variation in a test that measures parameters of pixels that are dependent upon the varied dimension. The method further includes performing the test on the set of baseline pixels and the set of varied pixels, analyzing the results of the test, and adjusting parameters of the manufacturing process in accordance with the analysis.
