Patent number: 11594593Abstract: Various embodiments of the present application are directed towards a method for forming a metal-insulator-metal (MIM) capacitor comprising an enhanced interfacial layer to reduce breakdown failure. In some embodiments, a bottom electrode layer is deposited over a substrate. A native oxide layer is formed on a top surface of the bottom electrode layer and has a first adhesion strength with the top surface. A plasma treatment process is performed to replace the native oxide layer with an interfacial layer. The interfacial layer is conductive and has a second adhesion strength with the top surface of the bottom electrode layer, and the second adhesion strength is greater than the first adhesion strength. An insulator layer is deposited on the interfacial layer. A top electrode layer is deposited on the insulator layer. The top and bottom electrode layers, the insulator layer, and the interfacial layer are patterned to form a MIM capacitor.Type: GrantFiled: October 14, 2021Date of Patent: February 28, 2023Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Hsing-Lien Lin, Chii-Ming Wu, Chia-Shiung Tsai, Chung-Yi Yu, Rei-Lin Chu

Patent number: 11581169Abstract: An ion collector includes a plurality of segments and a plurality of integrators. The plurality of segments are physically separated from one another and spaced around a substrate support. Each of the segments includes a conductive element that is designed to conduct a current based on ions received from a plasma. Each of the plurality of integrators is coupled to a corresponding conductive element. Each of the plurality of integrators is designed to determine an ion distribution for a corresponding conductive element based, at least in part, on the current conducted at the corresponding conductive element. An example benefit of this embodiment includes the ability to determine how uniform the ion distribution is across a wafer being processed by the plasma.Type: GrantFiled: December 5, 2019Date of Patent: February 14, 2023Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Otto Chen, Chi-Ying Wu, Chia-Chih Chen
