Patent number: 12063734Abstract: The present disclosure is directed to a modularized vessel droplet generator assembly (MGDVA) including a droplet generator assembly (DGA). Under a normal operation, the liquid fuel moves along an operation pathway extending through the DGA to eject or discharge the liquid fuel (e.g., liquid tin) from a nozzle of the DGA into a vacuum chamber. The liquid fuel in the vacuum chamber is then exposed to a laser generating an extreme ultra-violet (EUV) light. Under a service operation, the operation pathway is closed and a service pathway extending through the DGA is opened. A gas is introduced into the service pathway forming a gas-liquid interface between the gas and the liquid fuel. The gas-liquid interface is driven to an isolation valve directly adjacent to the DGA. In other words, the gas pushes back the liquid fuel to the isolation valve. Once the gas-liquid interface reaches the isolation valve, the isolation valve is closed isolating the DGA from the liquid fuel.Type: GrantFiled: September 23, 2021Date of Patent: August 13, 2024Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Yu-Kuang Sun, Ming-Hsun Tsai, Wei-Shin Cheng, Cheng-Hao Lai, Hsin-Feng Chen, Chiao-Hua Cheng, Cheng-Hsuan Wu, Yu-Fa Lo, Jou-Hsuan Lu, Shang-Chieh Chien, Li-Jui Chen, Heng-Hsin Liu
