Abstract:
Vacuum processing apparatus characterized in that said apparatus comprises:an atmospheric loader equipped with a plurality of cassette tables arranged close to each other, and with a transport unit for carrying wafers from or to said cassette tables, a vacuum loader equipped with vacuum wafer-processing chambers and with a vacuum transport chamber communicated with said processing chambers via gate valves, and a locking unit that includes loading and unloading lock chambers equipped with gate valves for connecting said atmospheric transport unit and vacuum transport chamber; said pair of vacuum wafer-processing chambers, both formed by a magnetized electromagnetic wave radiation discharge type system, wherein said chambers have wall inner units and antennas so mounted as to permit disassembly by opening said antennas almost in a horizontal direction, and said pair of vacuum wafer-processing chambers being arranged symmetrically with respect to the axial line passing through the middle of said vacuum transport chamber and locking unit, and only at the opposite side to said locking unit with respect to said vacuum transport chamber, and in such a manner that said pair of vacuum processing chambers form an acute angle with respect to said vacuum transport chamber.
