A large-sized dust-proof film having a dust-proof film area of l〇〇〇cm2 or more used for attaching foreign matter to a mask or a crosshair used in the lithography process, and can be housed in a stable plate and covered by a tray and a cover. A large-sized dust-proof film storage method and a storage structure thereof. [Prior Art] Conventionally, the production of a semiconductor circuit pattern or the like is a patent document 1 which will be described later, and a dustproof means called a dustproof film is generally used to prevent foreign matter from adhering to a mask or a crosshair. The dust-proof film is a transparent high surface of a frame having a thickness of a few millimeters in a shape of a mask or a crosshair, and exhibits a thickness of nitrocellulose or a cellulose-inducing body or a fluoropolymer which is not more than ΙΟμηη. The molecular film (hereinafter referred to as a dust-proof film) is coated with a bonding material on the lower edge surface of the frame, and the protective film is adhered to the bonding material with a predetermined bonding force. The adhesive material is used for fixing the dustproof film to the reticle or the cross wire, and the protective film is used to protect the adhesive material to maintain the bonding force of the adhesive material until it is used. The joint surface of the material. When the dust-proof film is transported from the manufacturer to the user, in order to prevent foreign matter from adhering to the dust-proof film or the like, or to prevent damage of the dust-proof film, the dust-proof film is generally housed in a case composed of a tray and a cover, and further stored in a dustproof manner. (4) (2) 1270745 The object of the present invention is a casing made of a tray and a cover that accommodates a large dust-proof film of 1.00 cm 2 or more, usually by vacuum forming. The formed and large tamper-proof film is housed in the case by being placed on the tray and covered by the cover. Further, in the production of the above-mentioned case, the space between the frame and the cover of the large dust-proof film housed in the case is designed to be manufactured to a range of 0 mm or more and 1 mm, and the cover is prevented from suppressing the large dust-proof film. In the case of a large-sized case in which a large-sized dust-proof film is slid and rubbed in the case due to the vibration of the medium, the large-sized dust-proof film is immersed in the case, but the area is a large-sized case in which a dust-proof film of 100 cm 2 or more is accommodated. In other words, in a large-sized case, there is a problem of the clearance of the dust-proof film and the case, or the case where the case cannot satisfy the requirement of flatness, and the interval between the entire circumference of the large-sized dust-proof film and the cover of the case cannot be accurately corrected. Since it is less than 1 mm of 〇mm or less, it is difficult to manufacture a large-sized shell while maintaining the molding precision for the conventional design idea. Therefore, when a large dust-proof film is housed in a large-sized case manufactured by a conventional design idea, when the gap between the large tamper-proof film and the cover is 0 mm, the cover is pressed against the large-sized dust-proof film, and the cover is pressed against the large-sized dust-proof film. Since the dust-proof film has a frame, dust is generated between the large dust-proof film during transportation, and foreign matter adheres to the large tamper-evident film. When the distance between the large dust-proof film and the cover is 1 mm or more, it is not stable by pressing the large dust-proof film by the cover. When the large-sized dust-proof film is moved, the large dust-proof film moves or vibrates inside the case, and the case and the large dust-proof film are Friction and dust occur, and foreign matter adheres to the large dust-proof membrane. -5- (3) (3) 1270745 In order to solve most of the problems described above, the applicant of the present patent has completed the invention of Patent Document 2, Patent Document 3 or Patent Document 4 which will be described later, and has filed a patent application. In the technique of Patent Document 2 described later, the protruding portion is erected on the surface of the tray of the dustproof film storage case, and a concave portion is provided on the side surface of the protruding portion, and the protective film of the dustproof film is inserted into the concave portion to be fixed. The technology of the dust-proof film placed on the tray. Further, in the technique of Patent Document 3, a viscous material having a predetermined adhesive force is applied to the underside of the protective film of the dust-proof film, and when the dust-proof film is mounted on the tray, the protective film is adhered to the _ tray. The technique of keeping the dustproof film fixed to the tray. Further, in the technique of Patent Document 4, a rod-shaped pressing body is suspended from the top surface of the cover of the case, and when the tray is placed in the tray, the dust is mounted on the tray by pressing the pressing body from above. In the protective film of the film, the tamper-proof film is fixed to the tray. 专利 [Patent Document 1] Japanese Patent Publication No. Sho 5 4 - 2 8 7 1 8 [Patent Document 2] JP-A-H11-38597 Φ [ [Patent Document 3] Japanese Patent Laid-Open Publication No. H-50238 (Patent Document 4). It is very effective for housing a dustproof film for semiconductors of 5 inches or 6 inches which is generally used in storage, but these inventions are applied to storage -6-(4) (4) 1270745 When the area of the dust-proof film of the object of the present invention is a shell for a large-sized dust-proof film of 1 000 cm 2 or more, there are several problems as will be described later. According to the technique of Patent Document 2, a vacuum forming method which is easy to manufacture and which is easy to manufacture is used, and a relatively deep concave portion is formed on the side surface of the protruding portion which is erected on the surface of the tray, which has a problem that sufficient molding accuracy cannot be obtained. In the case where the tray is formed by the injection molding method, it is possible to form the tray by the molding method. However, when the large-sized dustproof film of 1 000 cm 2 or more which is the object of the present invention is molded by the injection molding method, a very large molding is required. Therefore, since the size of the tray is large and the size of the tray is large, deformation occurs, and it is difficult to form a narrow recess in the side surface of the protruding portion with high precision. The technique of Patent Document 3 is a method of applying a bonding material to the underside of a protective film of a dust-proof film and bonding the protective film to the surface of the tray, which is effective for a shell of a small-sized semiconductor dust-proof film, but In the case of accommodating a large-sized case for a large-sized dust-proof film of the present invention, since the molding precision is not necessarily good, bending occurs at the place where the dust-proof film of the tray is mounted. Therefore, the deformation caused by the bending of the tray is rewritten to the protective film, and a part of the protective film is peeled off from the adhesive to reduce the adhesive force of the adhesive. For these reasons, the dustproof film is uniformly applied to the mask. It is difficult. The technique of Patent Document 4 is a method of holding and fixing a dust-proof film by pressing a protective film of a dust-proof film mounted on a tray by a pressing body suspended from a top surface of a cover of a case. In the case of this technology, for example, a semiconductor dust-proof film housing case can maintain the molding accuracy in the case of a small-sized case of 5 to 6 inches, but a large-sized -7- for storing a large-sized dust-proof film as the object of the present invention described above. (6) (6) 1270745 The pressing portion is superposed on the surface of the tray. Further, in the present invention, since the pressing portion is adhered to the tray by the adhesive tape, the dust-proof film can be surely held and fixed to the tray in a stable state by a very simple operation. Further, in the present invention, since the protective film of the large dust-proof film is bonded to the tray by the flexible adhesive tape, even if the forming accuracy of the tray is not good or the tray is bent, In the second aspect of the present invention, the large-sized dustproof film can be accurately and surely held in a tray. The second aspect of the present invention is a storage method of a large-sized dustproof film according to the first aspect of the present invention. The pressing portion has a forming width of 6 mm or more and a length of 20 mm or more. In the second aspect described above, the length of the pressing portion of the protective film is preferably 50 mm or more, and more preferably 300 mm or more. Further, when the area of the large-sized dustproof film is 4,000 cm2 or more, it is particularly effective if the length of the pressing portion of the protective film is 300 mm or more. In the second aspect, the size of the pressing portion of the protective film of the large-sized dust-proof film is 6 mm or more and 20 mm or more in length. Therefore, when the large dust-proof film is mounted on the tray, the pressing portion can be sufficiently It overlaps the surface of the tray, and the pressing portion can be stably and fixedly fixed to the surface of the tray by the adhesive tape. According to a third aspect of the present invention, there is provided a method of accommodating a large-sized dust-proof film according to the first or second aspect of the present invention, wherein a frame of a large dust-proof film mounted on a tray of the casing and a tray are covered by the tray There is at least 1 space between the covers. -9- (8) (8) 1270745 (Effects of the Invention) The present invention is to prevent foreign matter from adhering to a lithographic process in manufacturing a thin film transistor (TFT) or a color filter (CF) constituting a liquid crystal display (LCD). The reticle or the crosshair used in the present invention can be used for the storage method of the large dust-proof film having a dust-proof membrane area of 1 000 cm 2 or more and the storage structure thereof. In the method for accommodating the large-sized smash-proof film of the present invention and the accommodating structure, the part of the outer peripheral edge of the protective film of the tamper-proof film is protruded outward to form the pressing portion, so that the dust-proof film is mounted on the tray. There is an effect that the pressing portion that protrudes toward the outer side of the outer frame of the dustproof film can be superposed on the surface of the tray. Further, according to the present invention, since the pressing portion is adhered to the tray by the adhesive tape, the effect of reliably fixing the dustproof film tray in a stable state can be achieved by a very simple operation. Further, since the flexible pressing portion of the protective film of the dust-proof film is bonded to the tray by the flexible adhesive tape, even if the forming accuracy of the tray is insufficient or the tray is bent, There is no effect, and there is an effect that the dustproof film can be accurately and surely held in the tray. In the case where the pressure-receiving portion of the protective film of the dust-proof film is formed to have a width of 6 mm or more and a length of 20 mm or more, when the dust-proof film is mounted on the tray, the pressing portion can be sufficiently overlapped on the tray. The surface has an effect of stably holding the pressing portion to the surface of the tray by the adhesive tape. -11 - (9) (9) 1270745 In the present invention, even when at least 1 mm or more is formed between the casing of the large dust-proof membrane of the tray mounted on the casing and the cover covering the tray, When transporting a large dust-proof film, there is no need to worry about the contact of the large dust-proof film with the cover due to vibration or the like. Further, when the large-sized dust-proof film is held in a stable state by the adhesive tape as described above, it is not necessary to press the large dust-proof film by the cover. Therefore, the design of the case is easy, and even if the case is formed, The problem of accuracy or deformation can also be solved completely.
