Publication number: 20230170193Abstract: A method, device, server and computer-readable storage medium for monitoring particles in an etching chamber are provided. When performing a WAC process in the etching machine, an EPD data curve of spectral signal intensity varying with time in the etching machine can be obtained through an OES EPD module, the EPD data differential curve can be obtained through differentiation calculation performed on the EPD data curve, and a particle-drop determination can be performed on the etching chamber by acquiring and analyzing the peak value signal of the EPD data differential curve. The OES EPD module directly monitors particle dropping during the WAC process in the etching chamber, so as to facilitate subsequent processes. The present disclosure reduces labor cost, improves determination accuracy, and avoids contamination of the etching chamber and process wafers caused by particle droppings, thereby improving monitoring efficiency, reducing losses, and reducing negative impact on wafer quality.Type: ApplicationFiled: October 14, 2022Publication date: June 1, 2023Inventor: Zhiqin Shen

Patent number: 11215695Abstract: The present invention relates to the technical field of automobile maintenance and device calibration, discloses an on-board radar calibration device, the on-board radar calibration device including a laser-corner reflecting apparatus. The laser-corner reflecting apparatus includes a laser and a corner reflector, the corner reflector being mounted to the laser. The laser is configured to emit a laser, so as to calibrate positions of the corner reflector and an on-board radar. The corner reflector is configured to reflect a radar wave emitted by the on-board radar, so that the radar wave returns along an original path, to calibrate an installation angle of the on-board radar. In the present invention, the corner reflector and the on-board radar may be calibrated using the laser, and then the on-board may be calibrated using the corner reflector, without the help of other calibration apparatuses, simplifying operations for calibrating the on-board radar.Type: GrantFiled: July 10, 2020Date of Patent: January 4, 2022Assignee: AUTEL INTELLIGENT TECHNOLOGY CORP., LTD.Inventors: Zhiqin Shen, Xiaolong Wang, Jin Chen
