Abstract
In a vacuum processing device, a loading/unloading port, a normal pressure transfer chamber and a vacuum transfer chamber are arranged in that order from a front side toward a rear side, and load-lock chambers are connected to the normal pressure transfer chamber. The position in the front-rear direction in a movement range of a wafer W in the normal pressure transfer chamber overlaps with the positions in the front-rear direction of the load-lock chambers. Three vacuum processing modules are connected to each of the left and right sides of the vacuum transfer chamber. Vacuum processing units are arranged in each of the vacuum processing modules in a front-rear direction when viewed from the vacuum transfer chamber side. Wafer mounting shelves for holding wafers W in the load-lock chambers are arranged in the front-rear direction when viewed from the vacuum transfer chamber side.
