PELLICLE FRAME, PELLICLE, PELLICLE-ATTACHED EXPOSURE ORIGINAL PLATE, METHOD FOR MANUFACTURING SEMICONDUCTOR, METHOD FOR MANUFACTURING LIQUID CRYSTAL DISPLAY PLATE, AND EXPOSURE METHOD
摘要:
The present invention provides: a pellicle frame for EUV exposure characterized in that the pellicle frame is provided with at least one ventilation part, and a filter having a porous membrane coated with a resin is attached inside the ventilation part; a pellicle characterized in that a pellicle film is stretched on the pellicle frame; a pellicle-attached exposure original plate for EUV exposure characterized in that the pellicle is attached to the exposure original plate; a method for manufacturing a semiconductor; a method for manufacturing a liquid crystal display plate; and an exposure method. The pellicle frame of the present invention is sufficiently resistant to hydrogen radicals during EUV exposure.
