Patent number: 9826617Abstract: An extreme ultraviolet light source device that can stably and efficiently provide EUV emission. The EUV light source device includes a first laser source that irradiates a high-temperature plasma raw material with a laser beam, and a second laser source that, after the high-temperature plasma raw material is irradiated with the laser beam and before effective extreme ultraviolet light is emitted, irradiates the raw material in that region which is irradiated with the laser beam, with a second laser beam. The EUV light source device also includes a return light blocking unit that prevents return light of the laser beam, which is emitted from the first laser source, from reaching a light emission opening of the second laser source.Type: GrantFiled: May 22, 2015Date of Patent: November 21, 2017Assignee: USHIO DENKI KABUSHIKI KAISHAInventor: Takuma Yokoyama

Patent number: 9786702Abstract: An image sensor with an array of image sensor pixels is provided. Each image pixel may include a photodiode and associated pixel circuits formed in the front surface of a semiconductor substrate. Buried light shielding structures may be formed on the back surface of the substrate to prevent pixel circuitry that is formed in the substrate between two adjacent photodiodes from being exposed to incoming light. The buried light shielding structures may be lined with absorptive antireflective coating material to prevent light from being reflected off the surface of the buried light shielding structures. Forming buried light shielding structures with absorptive antireflective coating material can help reduce optical pixel crosstalk and enhance signal to noise ratio.Type: GrantFiled: August 27, 2013Date of Patent: October 10, 2017Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventor: Victor Lenchenkov

Patent number: 9787377Abstract: The disclosure provides for interference mitigation for wireless signals in unlicensed spectrum. A wireless device may receive a combined signal including a first radio access technology (RAT) signal and a second RAT signal. The wireless device may generate, using a first RAT receiver in a first processing path, a channel estimate for the first RAT signal based on a previously decoded signal of the first RAT. The wireless device may reduce interference to the second RAT signal caused by the first RAT signal, in a second processing path, using the channel estimate. The wireless device may further decode the second RAT signal. The wireless device may remodulate the decoded signal using a transmitter to generate a remodulated second RAT signal. The remodulated second RAT signal may be canceled from the combined signal. The wireless device may decode a remaining portion of the combined signal including the first RAT signal.Type: GrantFiled: December 17, 2014Date of Patent: October 10, 2017Assignee: QUALCOMM IncorporatedInventors: Boaz Kol, Assaf Touboul, Aaron Elazar Klein
