Patent number: 11952653Abstract: The present disclosure provides a sputtering reaction chamber and a process assembly of the sputtering reaction chamber. The process assembly includes a liner, and the liner includes an integrally formed body member and a cover member. The cover member may extend from a bottom of the body member to an inner side of the body member and may be configured to press an edge of a to-be-processed workpiece when a process is performed. A cooling channel may be arranged in the cover member and the body member and may be configured to cool the cover member and the body member by transferring coolant. The process assembly of the sputtering reaction chamber and the sputtering reaction chamber provided by the present disclosure can reduce heat radiation of the process assembly to the to-be-processed workpiece and released gases and impurities to effectively reduce a whisker defect and improve a product yield.Type: GrantFiled: January 13, 2021Date of Patent: April 9, 2024Assignee: BEIJING NAURA MICROELECTRONICS EQUIPMENT CO., LTD.Inventors: Liren Han, Bing Li, Keke Zhao, Lixin Pei, Guodong Bian

Publication number: 20230336082Abstract: An integrated circuit (IC) control device for a multi-phase switching converter having a master phase and at least one slave phase, has a first ON-time control circuit to provide a first ON-time control signal and at least one slave ON-time control circuit. Each slave ON-time control circuit has a closed-loop gainer to provide a gain by executing proportional integral to a difference between a master phase temperature and a slave phase temperature, a multiplier to provide a current feedback signal by multiplying a slave current signal with the gain, a bias circuit to provide a bias by executing proportional integral to a difference between a master phase current and the current feedback signal, and an adder to provide a corresponding slave ON-time control signal by adding the first ON-time control signal to a bias ON-time control signal provided by a bias ON-time generator based the bias.Type: ApplicationFiled: April 10, 2023Publication date: October 19, 2023Inventors: Huichun Dai, Wangmiao Hu, Fangyu Zhang, Keke Zhao, Lijie Jiang, Jinghai Zhou

Publication number: 20230299671Abstract: A controller used in a switching converter having a switch and converting an input voltage into an output voltage having a transient profile. The controller includes a transient sensing circuit, a mode determining circuit and an on time regulating circuit. The transient sensing circuit generates a transient voltage signal indicative of the transient profile of the output voltage. The mode determining circuit receives the transient voltage signal and a first feedback voltage signal indicative of the output voltage, and generates a mode signal based on a first comparison between the first feedback voltage signal and a first threshold voltage and a second comparison between the transient voltage signal and a second threshold voltage. The on time regulating circuit generates an on time signal to regulate an on time of the switch based on the mode signal.Type: ApplicationFiled: May 22, 2023Publication date: September 21, 2023Inventors: Keke Zhao, Wangmiao Hu, Ting Ma, Gang Yan, Lijie Jiang, Fangyu Zhang, Huichun Dai
