Latest Patents

Cheng-Hao Lai holds a patent for a "Droplet generator assembly and method of replacing components." This patent describes a modularized vessel droplet generator assembly (MGDVA) that includes a droplet generator assembly (DGA). Under normal operation, liquid fuel moves along an operation pathway through the DGA, ejecting the liquid fuel, such as liquid tin, from a nozzle into a vacuum chamber. The liquid fuel in the vacuum chamber is then exposed to a laser that generates extreme ultra-violet (EUV) light. During service operations, the operation pathway is closed, and a service pathway is opened, allowing gas to form a gas-liquid interface with the liquid fuel. This innovative mechanism enhances the efficiency and reliability of the droplet generation process.
