Patent number: 11920237Abstract: The present disclosure provides a multifunction chamber having a multifunctional shutter disk. The shutter disk includes a lamp device, a DC/RF power device, and a gas line on one surface of the shutter disk. With this configuration, simplifying the chamber type is possible as the various specific, dedicated chambers such as a degas chamber, a pre-clean chamber, a CVD/PVD chamber are not required. By using the multifunctional shutter disk, the degassing function and the pre-cleaning function are provided within a single chamber. Accordingly, a separate degas chamber and a pre-clean chamber are no longer required and the overall transfer time between chambers is reduced or eliminated.Type: GrantFiled: July 20, 2022Date of Patent: March 5, 2024Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Wen-Hao Cheng, Yen-Yu Chen, Yi-Ming Dai

Publication number: 20230352350Abstract: A deposition system provides a feature that may reduce costs of the sputtering process by increasing a target change interval. The deposition system provides an array of magnet members which generate a magnetic field and redirect the magnetic field based on target thickness measurement data. To adjust or redirect the magnetic field, at least one of the magnet members in the array tilts to focus on an area of the target where more target material remains than other areas. As a result, more ion, e.g., argon ion bombardment occurs on the area, creating more uniform erosion on the target surface.Type: ApplicationFiled: June 26, 2023Publication date: November 2, 2023Inventors: Wen-Hao CHENG, Hsuan-Chih CHU, Yen-Yu CHEN, Yi-Ming DAI

Patent number: 11742231Abstract: The present disclosure provides a flexible workpiece pedestal capable of tilting a workpiece support surface. The workpiece pedestal further includes a heater mounted on the workpiece support surface. The heater includes a plurality of heating sources such as heating coils. The plurality of heating sources in the heater allows heating the workpiece at different temperatures for different zones of the workpiece. For example, the workpiece can have a central zone heated by a first heating coil, a first outer ring zone that is outside of the central zone heated by a second heating coil, a second outer ring zone that is outside of the first outer ring zone heated by a third heating coil. By using the tunable heating feature and the tilting feature of the workpiece pedestal, the present disclosure can reduce or eliminate the shadowing effect problem of the related workpiece pedestal in the art.Type: GrantFiled: October 18, 2019Date of Patent: August 29, 2023Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Hsuan-Chih Chu, Wen-Hao Cheng, Yen-Yu Chen, Yi-Ming Dai
