Publication number: 20240266207Abstract: A susceptor configured to hold one or more WBG (Wide Bandgap) semiconductor wafers for epitaxial layer growth to support a manufacture of at least one WBG semiconductor device. A susceptor is removed from an epitaxial reactor when a predetermined thickness of polycrystalline WBG semiconductor material builds up from growing epitaxial layers on one or more WBG semiconductor wafers. The susceptor is scanned by a laser such that the energy from the laser is absorbed by the one or more layers of polycrystalline WBG semiconductor material to decompose the one or more layers of polycrystalline WBG semiconductor material into two or more constituent components. The two or more constituent components are then removed from the susceptor by etching to produce a cleaned susceptor. The cleaned susceptor can then be placed in an epitaxial reactor to grow epitaxial wafers on WBG semiconductor wafers.Type: ApplicationFiled: February 3, 2023Publication date: August 8, 2024Applicant: ThinSiC IncInventors: Tirunelveli Subramaniam Ravi, Ashraf Ahmed Eldakrouri

Publication number: 20240120284Abstract: A semiconductor substrate is configured for dicing into separate die or individual semiconductor devices. The semiconductor substrate can comprise silicon, silicon carbide, or gallium nitride. A dicing grid bounds each semiconductor device on the semiconductor substrate. A die singulation process is configured to occur in the dicing grid. Material is coupled to the dicing grid. In one embodiment, the material can comprise carbon. A laser is configured to couple energy to the material coupled to the dicing grid. The energy from the laser heats the material. The heat from the material or the temperature differential between the material and the dicing creates a thermal shock that generates a vertical fracture in the semiconductor substrate that separates the semiconductor device from the remaining semiconductor substrate.Type: ApplicationFiled: October 6, 2022Publication date: April 11, 2024Applicant: ThinSiC IncInventors: Tirunelveli Subramaniam Ravi, Stephen Daniel Miller, Jinho Seo, Ashraf Ahmed El dakrouri

Patent number: 10579391Abstract: Translation of boot code read request commands from an on-board processor of a system on a chip (SoC) from a bus protocol (e.g., advanced high-performance bus (AHB) protocol) into a sequence of commands understandable by a serial interface of the SoC to read boot code from an off-board (e.g., flash or other non-volatile) memory device. The serial interface of the memory device may include a relatively low pin count (e.g., 5 pins) and boot code of the memory device may be modified after tape-out of the SoC free of necessitating a subsequent tape-out of the SoC.Type: GrantFiled: July 31, 2013Date of Patent: March 3, 2020Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Erik Schlanger, Eric Devolder, Ashraf Ahmed

Patent number: 10379814Abstract: Embodiments of the present disclosure include a tininess prediction and handler engine for handling numeric underflow while streamlining the data path for handling normal range cases, thereby avoiding flushes, and reducing the complexity of a scheduler with respect to how dependent operations are handled. A preemptive tiny detection logic section can detect a potential tiny result for the function or operation that is being performed, and can produce a pessimistic tiny indicator. The tininess prediction and handler engine can further include a subnormal post-processing pipe, which can denormalize and round one or more subnormal operations while in a post-processing mode. A schedule modification logic section can reschedule in-flight operations. The schedule modification logic section can issue dependent operations optimistically assuming that a producing operation will not produce a tiny result, and so will not incur extra latency associated with fixing the tiny result in the post-processing pipe.Type: GrantFiled: March 23, 2018Date of Patent: August 13, 2019Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Ashraf Ahmed, Nicholas Todd Humphries, Marc Augustin

Patent number: 10328610Abstract: The method of recycling carbon fiber prepreg waste includes collecting uncured carbon fiber prepreg waste, where the carbon fiber prepreg waste still includes the backing film associated with the carbon fiber prepreg (typically in the form of a colored polyethylene layer). The uncured carbon fiber prepreg waste is then shredded and inserted into either an open or a closed mold. The mold is then inserted into a hot press, where the shredded carbon fiber prepreg waste is cured under selected temperature and pressure for a selected period of time, dependent upon the particular volume of waste and the desired recycled product. Alternatively, the shredded carbon fiber prepreg waste may be rolled in a hot metallic roller or extruded in a hot melt extruder.Type: GrantFiled: August 18, 2017Date of Patent: June 25, 2019Assignee: United Arab Emirates UniversityInventors: Waleed K. Ahmed, Ali Hilal-Alnaqbi, Aamna Salem Saeed Almazrouei, Lamia Aziz Alh Mohamed Almarzooqi, Dina Al Jamal, Farah Ashraf Ahmed Genena

Patent number: 10140092Abstract: According to one general aspect, an apparatus may include a floating-point multiply-accumulate unit configured to generate a floating point result by either adding or subtracting three floating point operands: an addend, a product carry, and a product sum. The floating-point multiply-accumulate unit may include a close path adder. The close path adder may include an unincremented mantissa addition circuit configured to compute an unincremented mantissa result based upon the three floating point operands. The close path adder may also include an incremented mantissa addition circuit configured to, at least partially in parallel with the mantissa addition circuit, produce an incremented mantissa result. The close path adder may further include a selection circuit configured to produce a close path result by selecting between the unincremented mantissa result and the incremented mantissa result.Type: GrantFiled: February 10, 2017Date of Patent: November 27, 2018Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventor: Ashraf Ahmed

Patent number: 10108397Abstract: Embodiments of the inventive concept include a fast close path solution and circuit of a three path fused multiply-adder circuit. The fast close path circuit can include one or more compressors that can receive multiple operands and produce a result sum and a result carry. The close path circuit can include one or more leading zero anticipators (LZAs). The one or more LZAs can receive and process the result sum and the result carry. The close path circuit can include one or more adders. The one or more adders can receive and add the result sum and the result carry in parallel with the one or more LZAs processing the result sum and the result carry. Since the close path is the critical timing path, by performing the addition operations in parallel with the LZA and/or priority encode (PENC) operations, the logic depth and latency of the close path are reduced.Type: GrantFiled: February 1, 2016Date of Patent: October 23, 2018Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventor: Ashraf Ahmed
