Embodiment Construction

[0039] Detailed embodiments of the present invention will be described below with reference to the accompanying drawings.

[0040] figure 1 A vacuum container according to one embodiment of the present invention is shown. This example will illustrate a hexahedral vacuum vessel. figure 2 yes figure 1 An exploded perspective view of the vacuum vessel shown in .

[0041] Such as figure 1 with2 As shown in , the vacuum container 1 includes a pair of curved members 20 and 30 . The bending members 20 and 30 are formed by bending a metal plate into a predetermined shape. The vacuum vessel 1 is formed by combining the curved members 20 and 30 with each other to form a closed space inside the curved members 20 and 30 . The vacuum vessel 1 also includes a sealing member 4 and a cubic lattice structure 5 . The sealing member 4 seals the gap in the joint portion between the bent members 20 and 30 . The structure 5 is housed in the closed space while abutting against the inner ...

Abstract

A vacuum vessel includes a pair of bending members which are formed by bending metal plates in predetermined shapes and are bonded to each other to form a closed space inside them. The vacuum vessel also includes a sealing member which seals the gap in the bonding portion between the bending members, and a cubic lattice structure which abuts against the inner surfaces of both the bending members and is accommodated in the closed space. The vacuum vessel further includes a magnet unit. The magnet unit fixes the bending members onto the structure and seals the gap in the bonding portion between the bending members by pressing an O-ring serving as a sealing member along the bonding portion.

Description

technical field [0001] The present invention relates to a vacuum container such as a process chamber or a transfer chamber, which constitutes a vacuum processing apparatus for processing, for example, a liquid crystal display substrate and a semiconductor wafer, and to a vacuum processing apparatus including the vacuum container, a vacuum container manufacturing method and method of manufacturing an electronic device. Background technique [0002] Processes such as thin film formation on, for example, liquid crystal display substrates and semiconductor wafers, and dry etching and heating of the formed thin films are mainly performed in a vacuum. Alignment, transport and the like, which prepare the processing objects for processing in a vacuum, are often also carried out continuously in a vacuum. In order to perform these processes, a vacuum processing apparatus formed by connecting a plurality of vacuum containers via gate valves is generally used (Japanese Patent Laid-Open...
