Problems solved by technology

However, when the temperature of the substrate rises excessively, the mechanical properties of the substrate are significantly reduced, and problems such as large deformation of the substrate and fusing of the substrate easily occur due to thermal expansion of the deposited film
In other film formation methods, although the heat source is different, the substrate is subjected to a thermal load during film formation, so the same problem exists

Embodiment approach 1

[0090] figure 1 It is a figure which schematically shows the structure of an example of the substrate coolant mechanism which is a part of embodiment of this invention provided with the tension application member in the width direction. figure 1 (a) is the AA' sectional view of (b), figure 1 (b) is from Figure 4 A front view of the film formation source 27 looking at the vicinity of the opening 31 .

[0091] Near both ends in the width direction of the substrate in the vicinity of the opening, along the back surface of the substrate, endless belts 3 held by a plurality of support rollers 2 are in contact with the back surface of the substrate in pairs and rotate (circularly). In addition, the surface of the subject of thin film formation facing the film formation source is defined as the front surface of the substrate, and the opposite surface is defined as the rear surface of the substrate. The width of the annular body 3 is preferably 2 to 50 mm. When the width of the a...

Abstract

Provided is a thin film forming apparatus uniformly and sufficiently cooling a substrate. The thin film forming apparatus of this invention forms a thin film on the long substrate in a vacuum and is provided with a cooling body 1 arranged in the vicinity of the backside of the substrate during conveying at an opening part 31, a gas introducing means introducing gas between the cooling body 1 and the substrate 21, and a substrate restraining means 3 restraining the vicinity of both edges in the width direction of the travelling substrate at the opening part 31.

Description

technical field [0001] The present invention relates to a thin film forming device and a forming method. Background technique [0002] Thin film technology is widely used in the high performance and miniaturization of devices. In addition, the thin film of the device not only directly benefits the user, but also plays an important role in the protection of the earth's resources and the reduction of power consumption. [0003] In the development of such thin film technology, it is indispensable to respond to the demands from the industrial application side such as high efficiency, stabilization, high productivity, and cost reduction of thin film manufacturing methods, and continuous efforts have been made in this regard. [0004] In terms of high productivity of thin films, film formation technology with high deposition rates is essential, and high deposition rates have been developed in thin film production such as vacuum evaporation, sputtering, ion plating, and CVD. In a...
