Embodiment

[0066] Hereinafter, examples of the present invention will be described, but the present invention is not limited thereto.

[0067] The pellicle storage container 10 shown in FIGS. 1 and 2 was produced. The structure of the pellicle assembly storage container 10 is mainly composed of a container body 1 and a container cover 2, both of which are antistatic ABS resin (surface resistance value 5×10 11 Ω / □) formed by molding.

[0068] In the pellicle assembly storage container 10 of FIG. 1 , the top surface of the cover body 2 is designed to form a convex shape even if bent due to its own weight, so that the top surface will not adhere to the pellicle 3 .

[0069] In the pellicle assembly storage container 10 of FIG. 2 , the top surface of the cover body 2 is designed to be in a gentle convex shape, so as to counteract the bending amount caused by the weight of the top surface itself and make it horizontal.

[0070] Fig. 3 is a diagram showing a vacuum forming mold used to manuf...

Abstract

The invention provides a photoetching protection film component container, which avoids defilement of the protection film and keeps quality in storage, transportation, and operation. The protection film component container is composed of container body carrying protection film and cover which covers and protects the protection film and blocks on the edge of the container body. The container characters in that: the container is designed to protuberant shape to avoid bending to the protection film by own weight.

Description

technical field [0001] The present invention relates to a storage container for a photolithographic pellicle assembly used as a dust-proof device when manufacturing articles such as semiconductor devices, printed substrates, and liquid crystal displays, and a method for manufacturing the same. Background technique [0002] In the manufacture of semiconductor devices such as LSI or articles such as liquid crystal displays, semiconductor wafers or glass substrates for liquid crystals are irradiated with light to form patterns. If the photomask or shrink photomask used at this time (hereinafter only If there is dust attached to the photomask), the dust will block the light or refract the light, causing damage to the transferred pattern. [0003] Therefore, such operations are usually performed in a clean room, and even then it is quite difficult to keep the photomask clean. Therefore, a method of attaching a pellicle assembly on the surface of the photomask as a dust preventer...
