Latest Patents
One of his latest patents is titled "Method and apparatus for in-situ reticle cleaning at photolithography tool." This invention presents a method and system for effectively cleaning a reticle, which is crucial in the photolithography process. The system includes a clean chamber where a reticle is placed, and a gas inert to the reticle is directed tangentially to its surfaces. The gas is exhausted from a location spaced from the opposing edges of the reticle, ensuring minimal contamination. The gas is applied in pulses, with specific parameters for pulse length and repetition rate, and can be ionized for enhanced cleaning efficiency. Additionally, the stepper chamber is designed to be vibrationally isolated from the blow-off chamber, and the cleaning operation is synchronized with the stepper operation to prevent interference during critical processes.
