Publication number: 20240113119Abstract: The present disclosure describes a method for the formation of gate-all-around nano-sheet FETs with tunable performance. The method includes disposing a first and a second vertical structure with different widths over a substrate, where the first and the second vertical structures have a top portion comprising a multilayer nano-sheet stack with alternating first and second nano-sheet layers. The method also includes disposing a sacrificial gate structure over the top portion of the first and second vertical structures; depositing an isolation layer over the first and second vertical structures so that the isolation layer surrounds a sidewall of the sacrificial gate structure; etching the sacrificial gate structure to expose each multilayer nano-sheet stack from the first and second vertical structures; removing the second nano-sheet layers from each exposed multilayer nano-sheet stack to form suspended first nano-sheet layers; forming a metal gate structure to surround the suspended first nano-sheet layers.Type: ApplicationFiled: December 1, 2023Publication date: April 4, 2024Inventors: Tetsu Ohtou, Ching-Wei Tsai, Jiun-Jia Huang, Kuan-Lun Cheng, Chi-Hsing Hsu

Patent number: 11773960Abstract: A linear transmission device with capability of real-time monitoring of an amount of a lubricant includes a long shaft, a moving part, a lubricating device and a detecting module. The lubricating device includes a shell and an oil containing unit. The shell is formed with a first accommodating space. The oil containing unit is disposed in the first accommodating space and configured to provide the lubricant to an outer surface of the long shaft. The detecting module includes a temperature sensing unit and a control unit. The temperature sensing unit is configured to detect a current temperature of the oil containing unit. The control unit is connected with the temperature sensing unit and configured to: receive the current temperature; calculate a remaining amount of the lubricant of the oil containing unit based on the current temperature and an oil releasing model; and output the remaining amount.Type: GrantFiled: October 31, 2021Date of Patent: October 3, 2023Assignee: HIWIN TECHNOLOGIES CORP.Inventors: Wei-Lun Liu, Yu-Hsin Lin, Chi-Lun Cheng
