Abstract:
1. A vacuum processing apparatus comprising: a vacuum transfer chamber of which the interior is maintained at a depressurized state; one or more vacuum process chambers, which are formed adjacent to and around the vacuum transfer chamber and where a predetermined process on a target object is performed in a depressurized interior; one or more load lock chambers, which are formed adjacent to and around the vacuum transfer chamber and have the interior that is selectively changed to an atmosphere state or a depressurized state to temporarily lock the target object transmitted between an atmosphere space and the vacuum transfer chamber; first and second vacuum transfer robots formed in the vacuum transfer chamber to transfer the target object, between the load lock chamber and at least one of the vacuum process chambers, or between the vacuum process chambers that are different from each other, wherein the first and second vacuum transfer robots are configured to move inside the vacuum transfer chamber respectively on first and second transfer paths that extend in inner depth directions respectively in a left transfer area and a right transfer area of the vacuum transfer chamber, as viewed from the load lock chamber side, the first vacuum transfer robot has access to all the vacuum process chambers adjacent to the left transfer area, at least one of the vacuum process chambers adjacent to the right transfer area, and at least one of the load lock chambers, so as to transfer in or out the target object, and the second vacuum transfer robot has access to all the vacuum process chambers adjacent to the right transfer area, at least one of the vacuum process chambers adjacent to the left transfer area, and at least one of the load lock chambers, so as to transfer in or out the target object.
