Patent number: 11973001Abstract: Semiconductor devices and methods of manufacture which utilize lids in order to constrain thermal expansion during annealing are presented. In some embodiments lids are placed and attached on encapsulant and, in some embodiments, over first semiconductor dies. As such, when heat is applied, and the encapsulant attempts to expand, the lid will work to constrain the expansion, reducing the amount of stress that would otherwise accumulate within the encapsulant.Type: GrantFiled: May 5, 2023Date of Patent: April 30, 2024Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Shu-Shen Yeh, Chin-Hua Wang, Chia-Kuei Hsu, Po-Yao Lin, Shin-Puu Jeng
