Application: Reticle inspection and purging method and tool (Patent ID: US20240103359A1)

The patent filed by Taiwan Semiconductor Manufacturing Co Ltd describes a method for reticle inspection and purging in lithography tools. The method involves moving a reticle from a load port to an inspection tool outside the lithography tool, inspecting the reticle, determining its suitability for exposure, and purging it if necessary. The process also includes calibrating the position and orientation of the reticle before inspection, as well as re-inspecting the reticle after purging.

Additionally, the patent outlines a tool that includes a reticle inspection tool, a reticle purging tool, a robot arm for transferring the reticle between different tools, an image analyzer to detect particle conditions on the reticle, and a purging controller to activate the purging tool based on the image analysis. The tool design features specific components such as inner and outer forks on the robot arm, an anti-collision bar, and a crash sensor for efficient and safe reticle handling during the inspection and purging process.
