Abstract:
Vacuum processing apparatus comprising:a plurality of cassette tables arranged close to each other, an atmospheric transport unit for carrying wafers from or to said cassette tables, a plurality of vacuum processing chambers, a vacuum transport chamber communicated with said vacuum processing chambers, and loading and unloading lock chambers equipped with gate valves for connecting said atmospheric transport unit and said vacuum transport chamber; wherein each of said vacuum processing chambers has side wall inner units and antennas so mounted as to permit disassembly, and said plurality of vacuum processing chambers are arranged symmetrically with respect to an axial line passing through the middle of the vacuum transport chamber and lock chambers, only at the opposite side of the lock chamber across the vacuum transport chamber, and in such a manner that the vacuum processing chambers form an acute angle with respect to the vacuum transport chamber, wherein said antennas are directed almost in parallel to said axial line, and each of said antenna is opened in almost horizontal position at the opposite side of said vacuum transport chamber.
