摘要:
A vapor deposition mask (70) includes a first layer (71), a second layer (72) and a third layer (73) in this order. A plurality of first openings (71h), a plurality of second openings (72h) and a plurality of third openings (73h) are formed respectively in the first layer, the second layer and the third layer. The first openings, the second openings and the third openings communicate with each other, thereby constituting mask openings (75). The opening dimension of the second openings is larger than the opening dimension of the first openings and is larger than the opening dimension of the third openings. With this configuration, it is possible to prevent reduction of the opening dimension of the mask openings or clogging of the mask openings due to the vapor deposition particles adhering to the mask openings.
摘要:
A vapor deposition source (60), a plurality of control plates (80) and a vapor deposition mask (70) are disposed in this order. A substrate (10) is moved relative to the vapor deposition mask in a state in which the substrate and the vapor deposition mask are spaced apart at a fixed interval. Vapor deposition particles (91) discharged from a vapor deposition source opening (61) of the vapor deposition source pass through neighboring inter-control plate spaces (81) and mask openings (71) formed in the vapor deposition mask, and then adhere to the substrate to form a coating film (90). At least a part of the coating film is formed by the vapor deposition particles that have passed through two or more different inter-control plate spaces. It is thereby possible to form a coating film in which edge blur and variations in the thickness are suppressed.

A vapor deposition device (50) in accordance with the present invention is a vapor deposition device for forming a film on a film formation substrate (60), the vapor deposition device including a vapor deposition source (80) that has an injection hole (81) from which vapor deposition particles are injected, a vapor deposition particle crucible (82) for supplying the vapor deposition particles to the vapor deposition source (80), and a rotation motor (86) for changing a distribution of the injection amount of the vapor deposition particles by rotating the vapor deposition source (80).
摘要:
A crucible (50) of the present invention includes: an opening (55a) from which vapor deposition particles are injected toward a film formation substrate on which a film is to be formed; a focal point member (54a), provided so as to face the opening (55a), which reflects vapor deposition particles injected from the opening (55a); and a revolution paraboloid (55b) which reflects, toward the film formation substrate, vapor deposition particles which have been reflected by the focal point member (54a).

A vapor deposition particle emitting device of the present invention includes: a nozzle section (110) having emission holes (111) from which gaseous vapor deposition particles are emitted out; a heating plate unit (100), provided in the nozzle section (110), which is made up of heating plates (101) each having a surface on which a vapor deposition material remains as a result of adherence of vapor deposition particles to the surface; and a heating device (160) for heating the vapor deposition material, which is thus remaining on the surface of each of the heating plates (101), so that a temperature of the vapor deposition material is not less than a temperature at which to become transformed into gaseous form.
摘要:
A vapor deposition device (50) includes a mask (60) having periodic patterns, and only a region of the mask (60) where a one-period pattern is formed is exposed. A length of the mask base material along a direction perpendicular to a long-side direction of the mask base material is shorter than a length of a film formation substrate (200) along a direction of scanning of the film formation substrate (200). The mask (60) is provided so that the long-side direction of the mask base material is perpendicular to the direction of scanning and that the exposed region is allowed to move in a direction perpendicular to the direction of scanning by rotation of a wind-off roll (91) and a wind-up roll (92).

A vapor deposition particle injection device (501) of the present invention includes: vapor deposition particle generating sections (110) and (120) for generating vapor deposition particles in the form of vapor by heating vapor deposition materials (114) and (124); and a nozzle section (170) which (i) is connected to the vapor deposition particle generating sections (110) and (120) and (ii) has an injection hole (171) from which the vapor deposition particles generated by the vapor deposition particle generating sections (110) and (120) are injected outward. The vapor deposition particle generating section (120) has a smaller capacity for the vapor deposition material than the vapor deposition particle generating section (110).
摘要:
A film formation substrate (200) is arranged such that (i) a base end, in a y-axis direction, of a film-thickness-gradually-diminishing part (23sR) of a first film (23R) overlaps a first film formation region (24R), and (ii) a film-thickness-gradually-diminishing part (23sB) of a second film (23B) is disposed on an outside, in the y-axis direction, of a second film formation region (24B) and overlaps the film-thickness-gradually-diminishing part (23sR) of the first film (23R) so as to compensate for a gradually diminished thickness of the film-thickness-gradually-diminishing part (23sR).
摘要:
A layer (71), made from a material that is attracted by a magnet, is formed in at least part of a chamber component (70), which at least part makes in contact with a film forming material. A method for collecting a film forming material includes the steps of: (a) exfoliating an attachment (22) which has attached to a surface of the chamber component (70); and (b) collecting the attachment (22) by separating a fragment of the layer (71), which fragment has been exfoliated in the step (a), while causing the fragment to be attracted by a magnet (202a).

A vapor deposition method of the present invention includes the steps of (i) preparing a mask unit including a shadow mask (81) and a vapor deposition source (85) fixed in position relative to each other, (ii) while moving at least one of the mask unit and the film formation substrate (200) relative to the other, depositing a vapor deposition flow, emitted from the vapor deposition source (85), onto a vapor deposition region (210), and (iii) adjusting the position of a second shutter (111) so that the second shutter (111) blocks a vapor deposition flow traveling toward the vapor deposition unnecessary region (210).
