Processing apparatus and method of manufacturing electron emission element and organic el display

Abstract

Highly accurate batch pattern film formation is made possible even when using a mask, which has a possibility of deteriorating pattern alignment accuracy due to heavy weight as a result of meeting the requirement of size increase of a subject to be processed. Specifically, a processing apparatus (1), which performs processing by fixing a subject (300) to be processed and a mask (200), is provided with a base (400) for placing the subject (300) and the mask (200). Furthermore, the processing apparatus is provided with a second fixing means (101), which includes a permanent magnet for fixing a mask frame (200a) of the mask (200) on the base (400). The processing apparatus is also provided with a first fixing means (102), which includes a permanent magnet for fixing a mask-film-like flat surface (200b) of the mask (200) on the base (400). The second fixing means (101) and the first fixing means (102a, 102b) respectively have mechanisms wherein each permanent magnet can move the base (400) in the vertical direction.

Description

technical field [0001] The present invention relates to a processing device for forming a desired pattern on a surface other than a mask-covered area by adhering and fixing a mask on an object to be processed for film formation and the like, and an electron emission device and an electron emission device using the processing device. A production method of an organic EL display. Background technique [0002] As an example of a manufacturing apparatus of an image display device, there exist a glass substrate manufacturing apparatus for flat panel displays represented by an organic electroluminescence element, etc. Such a substrate for a display is usually provided with a desired function by forming a desired pattern on the substrate with desired precision. [0003] Vacuum deposition, sputtering, photolithography, screen printing, and the like are known as pattern forming methods, but currently, higher-definition display capabilities are required for displays. Therefore, fine...

AI Technical Summary

Problems solved by technology

[0039] In this way, when glass is used as the object of film formation, additional countermeasures are required, and as a result, new problems such as increased production tact of the device and increased cost arise.

[0040] In addition, since the step of improving the adhesion between the mask and the object to be processed disclosed in Patent Document 6 is fixed sequentially from one end all the time, the degree of freedom when the size of the object to be processed is changed is limited. limit such problems

[0041] In particular, when coping with the increase in width of the substrate to be processed, there is a problem that the design freedom and expandability of the device are limited.
