Method of manufacturing pellicle and apparatus for assembling pellicle
A method of manufacturing a pellicle includes preparing a pellicle frame having an adhesive layer coated thereon, treating a pellicle membrane with vapor under vapor atmosphere, attaching the pellicle membrane onto the pellicle frame, and drying the pellicle membrane.
1. A method of manufacturing a pellicle, the method comprising:
attaching a pellicle membrane onto a handling frame;
preparing a pellicle frame having an adhesive layer coated thereon;
treating the pellicle membrane attached onto the handling frame with vapor under vapor atmosphere;
after treating the pellicle membrane with the vapor, attaching the pellicle membrane onto the pellicle frame; and
drying the pellicle membrane,
wherein attaching the pellicle membrane onto the pellicle frame includes stamping the handling frame having the pellicle membrane thereon on the pellicle frame.
2. The method as claimed in claim 1 , wherein preparing the pellicle frame having the adhesive layer coated thereon includes coating a gel-phase adhesive layer on a surface of the pellicle frame.
3. The method as claimed in claim 1 , wherein the pellicle frame has an outer diameter of a first size, the handling frame has an opening in a middle region, and the opening has an inner diameter of a second size greater than the first size.
4. The method as claimed in claim 1 , further comprising treating the adhesive layer with the vapor while treating the pellicle membrane with the vapor.
5. The method as claimed in claim 1 , wherein treating the pellicle membrane with the vapor includes contacting at least one surface of the pellicle membrane with the vapor.
6. The method as claimed in claim 1 , wherein a drop in the vapor has a diameter of about 1 nm to about 10 μm.
7. The method as claimed in claim 1 , further comprising loading the pellicle frame having the adhesive layer coated thereon onto a pellicle support within a chamber.
8. The method as claimed in claim 7 , wherein treating the pellicle membrane with the vapor includes vaporizing a liquid received within a bath under the pellicle support to maintain the chamber under the vapor atmosphere.
9. The method as claimed in claim 1 , wherein attaching the pellicle membrane onto the pellicle frame occurs only after treating the pellicle membrane with vapor is complete.
10. A method of manufacturing a pellicle, the method comprising:
attaching a pellicle membrane onto a handling frame;
preparing a pellicle frame having an adhesive layer coated thereon;
loading the pellicle frame onto a pellicle support within a chamber;
loading the pellicle membrane attached onto the handling frame into a space over the pellicle support within the chamber;
vaporizing a liquid received within a bath under the pellicle support to maintain the chamber under vapor atmosphere;
after vaporizing the liquid, attaching the pellicle membrane onto the pellicle frame; and
drying the pellicle membrane,
wherein attaching the pellicle membrane onto the pellicle frame includes stamping the handling frame having the pellicle membrane thereon on the pellicle frame.
11. The method as claimed in claim 10 , wherein preparing the pellicle frame having the adhesive layer coated thereon includes coating a gel-phase adhesive layer on a surface of the pellicle frame.
12. The method as claimed in claim 10 , wherein the pellicle frame has an outer diameter of a first size, the handling frame has an opening in a middle region, and the opening has an inner diameter of a second size greater than the first size.
13. The method as claimed in claim 10 , wherein vaporizing the liquid includes directing the vaporized liquid through an opening in the pellicle frame into the pellicle membrane.
14. The method as claimed in claim 10 , wherein vaporizing the liquid includes vaporizing water.
