Patent number: 12224179Abstract: The current disclosure describes techniques of protecting a metal interconnect structure from being damaged by subsequent chemical mechanical polishing processes used for forming other metal structures over the metal interconnect structure. The metal interconnect structure is receded to form a recess between the metal interconnect structure and the surrounding dielectric layer. A metal cap structure is formed within the recess. An upper portion of the dielectric layer is strained to include a tensile stress which expands the dielectric layer against the metal cap structure to reduce or eliminate a gap in the interface between the metal cap structure and the dielectric layer.Type: GrantFiled: March 15, 2023Date of Patent: February 11, 2025Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Yi-Sheng Lin, Chi-Jen Liu, Chi-Hsiang Shen, Te-Ming Kung, Chun-Wei Hsu, Chia-Wei Ho, Yang-Chun Cheng, William Weilun Hong, Liang-Guang Chen, Kei-Wei Chen

Patent number: 10459341Abstract: Embodiments of the present disclosure generally provide a digital lithography system that can process both large area substrates as well as semiconductor device substrates, such as wafers. Both the large area substrates and the semiconductor device substrates can be processed in the same system simultaneously. Additionally, the system can accommodate different levels of exposure for forming the features over the substrates. For example, the system can accommodate very precise feature patterning as well as less precise feature patterning. The different exposures can occur in the same chamber simultaneously. Thus, the system is capable of processing both semiconductor device substrates and large area substrates simultaneously while also accommodating very precise feature patterning simultaneous with less precise feature patterning.Type: GrantFiled: December 11, 2018Date of Patent: October 29, 2019Assignee: APPLIED MATERIALS, INC.Inventors: Chien-Hua Lai, Ching-Chang Chen, Shih-Hao Kuo, Tsu-Hui Yang, Hsiu-Jen Wang, Yi-Sheng Liu, Chia-Hung Kao
