Patent number: 12369329Abstract: 1. Various embodiments of the present disclosure are directed towards a ferroelectric random-access memory (FeRAM) cell or some other suitable type of memory cell comprising a bottom-electrode interface structure. The memory cell further comprises a bottom electrode, a switching layer over the bottom electrode, and a top electrode over the switching layer. The bottom-electrode interface structure separates the bottom electrode and the switching layer from each other. Further, the interface structure is dielectric and is configured to block or otherwise resist metal atoms and/or impurities in the bottom electrode from diffusing to the switching layer. By blocking or otherwise resisting such diffusion, leakage current may be decreased. Further, endurance of the memory cell may be increased.Type: GrantFiled: July 18, 2023Date of Patent: July 22, 2025Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Tzu-Yu Lin, Chia-Wen Zhong, Yao-Wen Chang

Publication number: 20250232959Abstract: Some implementations described herein provide a deposition tool and methods of operation. The deposition tool may be used in the fabrication of integrated circuit devices to deposit materials and/or layers on a semiconductor substrate. The deposition tool may include a chamber (e.g., a processing chamber) that is coated with a dielectric coating on sidewalls of the chamber. The dielectric coating on the sidewalls of the chamber within the deposition tool increases a likelihood of a negative charge accumulating near the sidewalls of the chamber. The increased likelihood of negative charge accumulation near the sidewalls of the chamber may improve a uniformity of an electromagnetic field within the deposition tool (e.g., during a deposition operation) relative to another deposition too not including such a dielectric coating. The improved uniformity of the electromagnetic field may enable an improved uniformity of a material being deposited by the deposition tool to be achieved.Type: ApplicationFiled: January 12, 2024Publication date: July 17, 2025Inventors: Yen-Liang LIN, Ru-Liang LEE, Chung-Yi YU, Yao-Wen CHANG, Kuo Liang KU, Bo-Han CHU, Min-Chang CHING
