Pellicle Frame, Pellicle, Exposure Original Plate with Pellicle and Exposure Method, and Method for Manufacturing Semiconductor Device or Liquid Crystal Display Board
摘要:
The present invention provides a frame-shaped pellicle frame having an upper end surface on which a pellicle film is provided and a lower end surface facing a photomask, characterized in that the inner surface of the pellicle frame has a region where a roughness curve kurtosis (Rku) is 3.0 or less, and also provides a pellicle, an exposure original plate with a pellicle and an exposure method, and a method for manufacturing a semiconductor device or a liquid crystal display board. The present invention can provide a pellicle frame that prevents scattered light derived from the frame and facilitates inspection of foreign matter adhered to the frame surface, and can also provide a pellicle using the pellicle frame.
