Publication number: 20230355083Abstract: A tethered opto-electronic imaging system encapsulated in an optically-transmissible housing capsule/shell and configured to image object space in multiple fields-of-view (FOVs) to form a visually-perceivable representation of the object space in which sub-images representing different FOVs remain co-directional regardless of mutual repositioning of the object and the imaging system. The capsule/shell of the system is a functionally-required portion of the train of optical components that aggregately define and form a lens of the optical imaging system. The tether is devoid of any functional optical channel or element. When different FOVs are supported by the same optical detector, co-directionality of formed sub-images images is achieved due via judicious spatial re-distribution of irradiance of an acquired sub-image to form a transformed sub-image while maintaining aspect ratios of dimensions of corresponding pixels of the acquired and transformed sub-images.Type: ApplicationFiled: July 18, 2023Publication date: November 9, 2023Applicant: OMNISCIENT IMAGING INC.Inventors: Bhaskar Banerjee, Brian Scaramella, Richard Pfisterer, Scott Ellis, Andrew Sapozink, Chih-Chiang Chang

Publication number: 20230362515Abstract: A method is provided for forming a light-shielding layer to block irradiation of light onto a light-sensitive storage region. The light-sensitive storage region is formed in a semiconductor substrate to store electric charges. A storage gate feature is formed over the light-sensitive storage region, and includes a polysilicon gate electrode that is disposed over the light-sensitive storage region. A metal layer is formed over the storage gate feature. A silicidation process is performed to transform a part of the metal layer that is in contact with the polysilicon gate electrode into a silicide light-shielding layer. A thermal process is performed to induce lateral growth of the silicide light-shielding layer to make the silicide light-shielding layer extend to cover a lateral surface of the storage gate feature. A process temperature of the thermal process is higher than that of the silicidation process.Type: ApplicationFiled: May 9, 2022Publication date: November 9, 2023Applicant: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.Inventors: Yueh-Chuan LEE, Chih-Chiang CHANG, Chia-Chan CHEN

Publication number: 20230186008Abstract: An electronic design flow generates an electronic architectural design layout for analog circuitry from a schematic diagram. The electronic design flow assigns analog circuits of the schematic diagram to various categories of analog circuits. The electronic design flow places various analog standard cells corresponding to these categories of analog circuits into analog placement sites assigned to the analog circuits.
