Publication number: 20230383397Abstract: Some implementations described herein provide a shutter disc for use during a conditioning process within a processing chamber of a deposition tool. The shutter disc described herein includes a material having a wave-shaped section to reduce heat transfer to the shutter disc and to provide relief from thermal stresses. Furthermore, the shutter disc includes a deposition of a thin-film material on a backside of the shutter disc, where a diameter of the shutter disc causes a spacing between an inner edge of the thin-film material and an outer edge of a substrate support component. The spacing prevents an accumulation of material between the thin film material and the substrate support component, reduces tilting of the shutter disc due to a placement error, and reduces heat transfer to the shutter disc.Type: ApplicationFiled: August 10, 2023Publication date: November 30, 2023Inventors: Yi-Lin WANG, Chin-Szu LEE, Hua-Sheng CHIU, Yi-Chao CHANG, Zih-Shou MUE

Patent number: 10859597Abstract: A bias value associated with a sensor, e.g., a time-varying, non-zero value which is output from a sensor when it is motionless, is estimated using a ZRO-tracking filter which is a combination of a moving-average filter and a Kalman filter having at least one constraint enforced against at least one operating parameter of the Kalman filter. It achieves faster convergence on an estimated bias value and produces less estimate error after convergence. A resultant bias estimate may then be used to compensate the biased output of the sensor in, e.g., a 3D pointing device.Type: GrantFiled: February 10, 2014Date of Patent: December 8, 2020Assignee: IDHL Holdings, Inc.Inventors: Hua Sheng, Bryan A.

Patent number: 10393801Abstract: The present invention provides a method and a fault isolation system for detecting errors in an integrated circuit. One feature of the present invention is using a movable second probe to scan and acquire an output signal through the vias or metal line structure of a diagnostic area along a detecting line, so as to find the fault location precisely, and another feature of the present invention is using a cutter in conjunction with the above method to narrow down the fault range. The cutter is used to electrically isolate the portion of diagnostic area step by step for approaching the fault location. This method can help to save a lot of analysis time and also makes the minor fault localization possible.Type: GrantFiled: September 26, 2017Date of Patent: August 27, 2019Assignee: Micron Technology, Inc.Inventors: Wei-Chih Wang, Bi-Jen Chen, Hua-Sheng Chen
