Patent number: 11854970Abstract: Circuit devices, such as integrated circuit devices, are constructed with combination circuits that include two or more cascading transistors, and one or more metal layers disposed over the cascading transistors. The cascading transistors include multiple internal nodes (e.g., common source/drain regions). The multiple internal nodes are not connected to a common metal stripe (the same metal stripe) in the one or more metal layers. The absence of the connections between the internal nodes and a common metal stripe reduce or eliminate the load on the internal nodes. The transistors in the cascading transistors are independent of each other.Type: GrantFiled: July 29, 2022Date of Patent: December 26, 2023Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chien-Yuan Chen, Cheng-Hung Lee, Hung-Jen Liao, Hau-Tai Shieh, Kao-Cheng Lin, Wei-Min Chan
