Patent number: 11955370Abstract: A system and methods of forming a dielectric material within a trench are described herein. In an embodiment of the method, the method includes introducing a first precursor into a trench of a dielectric layer, such that portions of the first precursor react with the dielectric layer and attach on sidewalls of the trench. The method further includes partially etching portions of the first precursor on the sidewalls of the trench to expose upper portions of the sidewalls of the trench. The method further includes introducing a second precursor into the trench, such that portions of the second precursor react with the remaining portions of the first precursor to form the dielectric material at the bottom of the trench.Type: GrantFiled: September 18, 2020Date of Patent: April 9, 2024Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Bo-Cyuan Lu, Ting-Gang Chen, Sung-En Lin, Chunyao Wang, Yung-Cheng Lu, Chi On Chui, Tai-Chun Huang, Chieh-Ping Wang

Publication number: 20240098330Abstract: A display device and a signal source switching method therefore are provided. The display device is connected with a first signal source device and a second signal source device and includes a switching circuit, a receiver circuit and a control circuit. The switching circuit includes a first connection port and a second connection port, which are respectively connected to the first signal source device and the second signal source device. When the control circuit receives a signal source switching command, the control circuit records a current operating state of each of the first signal source device and the second signal source device. When the control circuit receives an active source command from the first signal source device, the control circuit refers to the current operating state to control the switching circuit to switch the image signal source to the first signal source device or the second signal source device.Type: ApplicationFiled: June 16, 2023Publication date: March 21, 2024Applicant: Qisda CorporationInventors: Bo-Wei Shih, Li-Chun Chen, I-Hsuan Lai
