Abstract

A substrate transfer apparatus for transferring a substrate includes a plurality of vacuum transfer chambers, each having therein a substrate transfer mechanism for holding and transferring the substrate, and an intermediate chamber disposed between the vacuum transfer chambers adjacent to each other. When one of the vacuum transfer chambers adjacent to each other is set as a first vacuum transfer chamber and the other is set as a second vacuum transfer chamber, a first substrate loading/unloading port is disposed between the intermediate chamber and the first vacuum transfer chamber and a second substrate loading/unloading port is disposed between the intermediate chamber and the second vacuum transfer chamber. A gate valve is provided only for the second substrate loading/unloading port. Further, the first and the second substrate loading/unloading port have different height positions.
