Patent number: 12650642Abstract: A method of manufacturing a semiconductor device includes forming a photoresist layer over a substrate, including combining a first precursor and a second precursor in a vapor state to form a photoresist material, and depositing the photoresist material over the substrate. A protective layer is formed over the photoresist layer. The photoresist layer is selectively exposed to actinic radiation through the protective layer to form a latent pattern in the photoresist layer. The protective layer is removed, and the latent pattern is developed by applying a developer to the selectively exposed photoresist layer to form a pattern.Type: GrantFiled: July 26, 2024Date of Patent: June 9, 2026Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.Inventors: Ming-Hui Weng, Chen-Yu Liu, Chih-Cheng Liu, Yi-Chen Kuo, Jia-Lin Wei, Yen-Yu Chen, Jr-Hung Li, Yahru Cheng, Chi-Ming Yang, Tze-Liang Lee, Ching-Yu Chang

Patent number: 12487523Abstract: Metal-comprising resist layers (for example, metal oxide resist layers), methods for forming the metal-comprising resist layers, and lithography methods that implement the metal-comprising resist layers are disclosed herein that can improve lithography resolution. An exemplary method includes forming a metal oxide resist layer over a workpiece by performing deposition processes to form metal oxide resist sublayers of the metal oxide resist layer over the workpiece and performing a densification process on at least one of the metal oxide resist sublayers. Each deposition process forms a respective one of the metal oxide resist sublayers. The densification process increases a density of the at least one of the metal oxide resist sublayers. Parameters of the deposition processes and/or parameters of the densification process can be tuned to achieve different density profiles, different density characteristics, and/or different absorption characteristics to optimize patterning of the metal oxide resist layer.Type: GrantFiled: April 15, 2021Date of Patent: December 2, 2025Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.Inventors: Yi-Chen Kuo, Chih-Cheng Liu, Yen-Yu Chen, Jr-Hung Li, Chi-Ming Yang, Tze-Liang Lee

Patent number: 12127430Abstract: A device includes a micro-organic light emitting diode (?-OLED) display panel and an electronic component. An electrical connector electrically couples the ?-OLED display panel and the electronic component. A standoff is disposed between the electronic component and the ?-OLED display panel. The standoff physically couples the electronic component and the ?-OLED display panel with a gap therebetween. The gap thermally decouples the electronic component from the ?-OLED display panel. A U-shaped heat sink can be disposed in the standoff, and heat generated by the ?-OLED display can be mitigated by a system fan when a U-shaped heat sink is disposed in the standoff.Type: GrantFiled: January 31, 2022Date of Patent: October 22, 2024Assignee: Meta Platforms Technologies, LLCInventors: Giti Karimi Moghaddam, Douglas Moskowitz, Kyung Won Park, Ryan Fleming, Alexander Klement, Donghee Nam, Yi-Chen Kuo, Mark Shintaro Ando
