Patent number: 10770613Abstract: A semiconductor wafer forms on a mold containing a dopant. The dopant dopes a melt region adjacent the mold. There, dopant concentration is higher than in the melt bulk. A wafer starts solidifying. Dopant diffuses poorly in solid semiconductor. After a wafer starts solidifying, dopant can not enter the melt. Afterwards, the concentration of dopant in the melt adjacent the wafer surface is less than what was present where the wafer began to form. New wafer regions grow from a melt region whose dopant concentration lessens over time. This establishes a dopant gradient in the wafer, with higher concentration adjacent the mold. The gradient can be tailored. A gradient gives rise to a field that can function as a drift or back surface field. Solar collectors can have open grid conductors and better optical reflectors on the back surface, made possible by the intrinsic back surface field.Type: GrantFiled: September 4, 2019Date of Patent: September 8, 2020Assignee: 1366 TECHNOLOGIES INC.Inventors: Ralf Jonczyk, Brian D.

Patent number: 10453877Abstract: A CMOS detector with pairs of interdigitated elongated finger-like collection gates includes p+ implanted regions that create charge barrier regions that can intentionally be overcome. These regions steer charge to a desired collection gate pair for collection. The p+ implanted regions may be formed before and/or after formation of the collection gates. These regions form charge barrier regions when an associated collection gate is biased low. The barriers are overcome when an associated collection gate is high. These barrier regions steer substantially all charge to collection gates that are biased high, enhancing modulation contrast. Advantageously, the resultant structure has reduced power requirements in that inter-gate capacitance is reduced in that inter-gate spacing can be increased over prior art gate spacing and lower swing voltages may be used. Also higher modulation contrast is achieved in that the charge collection area of the low gate(s) is significantly reduced.Type: GrantFiled: February 1, 2017Date of Patent: October 22, 2019Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventor: Cyrus Bamji

Patent number: 10157956Abstract: A method for monolithic integration of a hyperspectral image sensor is provided, which includes: forming a bottom reflecting layer on a surface of the photosensitive region of a CMOS image sensor wafer; forming a transparent cavity layer composed of N step structures on the bottom reflecting layer through area selective atomic layer deposition processes, where N=2m, m?1 and m is a positive integer; and forming a top reflecting layer on the transparent cavity layer. With the method, non-uniformity accumulation due to etching processes in conventional technology is minimized, and the cavity layer can be made of materials which cannot be etched. Mosaic cavity layers having such repeated structures with different heights can be formed by extending one-dimensional ASALD, such as extending in another dimension and forming repeated regions, which can be applied to snapshot hyperspectral image sensors, for example, pixels, and greatly improving performance thereof.Type: GrantFiled: April 3, 2017Date of Patent: December 18, 2018Assignee: INSTITUTE OF MICROELECTRONICS, CHINESE ACADEMY OF SCIENCESInventors: Hushan Cui, Jinjuan Xiang, Xiaobin He, Tao Yang, Junfeng Li, Chao Zhao

Patent number: 10139496Abstract: A multi-radiation identification and dosimetry system and method that allows for monitoring of alpha, beta, and gamma radiation is disclosed. The system/method incorporates a segmented silicon drift detector (SSDD) that allows measurement of directly absorbed radiation in the semiconductor (betas, conversion electrons, Lx lines, and alphas) on one SSDD segment and radiation from a radiation scintillation detector (RSD) on multiple segments of the SSDD. With the anode side of the SSDD directed toward the radiation inspection surface (RIS), the SSDD+RSD stacked radiation detector collects radiation which is processed by a charge sensitive amplifier (CSA) and then processed by a time stamping differentiator (TSD). A computing control device (CCD) may be configured to collect the time stamp differentiation data from the various SSDD segments to permit the simultaneous discrimination of several types of radiation by and presentation of these radiation types and counts on a display monitor.Type: GrantFiled: December 9, 2015Date of Patent: November 27, 2018Assignee: MIRION TECHNOLOGIES (CANBERRA), INC.Inventors: Olivier Roger Evrard, Roger Abou-Khalil, Stephane Dogny, Nabil Menaa, Wilhelm Friedrich Mueller, Mathieu Morelle, Edward Lee Reagan
