Abstract:
1. A vacuum processing apparatus comprising a process chamber in which vacuum processing takes place, a substrate transfer chamber which is connected to the process chamber, and includes a substrate storage unit which stores a plurality of substrates, a substrate transport path which runs through the process chamber and the substrate transfer chamber, a plurality of carriers which are transported along the substrate transport path while each of the plurality of carriers mounts at least two substrates, and a substrate transfer robot which transfers the substrates stored in the substrate storage unit onto one of the plurality of carriers stopped at a substrate transfer position set to a predetermined position in the substrate transport path in the substrate transfer chamber, wherein the substrate transfer robot comprises a driving shaft, a first arm connected to said driving shaft, a second arm rotatably connected to said first arm, and an end effector rotatably disposed on said second arm, said end effector comprising a first holding group including not less than two holding units, each of which holds at least two substrates in one direction, and a second holding group including not less than two holding units, each of which holds at least two substrates in an opposite direction, and wherein said holding units of said second holding group face the substrate storage unit when said holding units of said first holding group are opposed to the carrier stopped at the substrate transfer position.
