Patent ID: 8588962

Claim:
A vacuum processing device comprising: a load lock that takes in a process subject member placed on an atmosphere-side to a vacuum-side; a plurality of process chambers that are connected to a transport chamber provided on the vacuum-side and perform a predetermined process on the process subject member; a plurality of transportation mechanism units that include a vacuum robot that performs passing and transportation of the process subject member; a plurality of buffer rooms that interconnect the transportation mechanism units and in which the process subject member is placed to be relayed; a holding mechanism unit that is provided in the load locks and the buffer rooms and holds a plurality of the process subject members; and a control unit that controls passing and transportation of the process subject member, wherein the control unit updates in real time and holds device state information showing an action state of each of the process chambers, the transportation mechanism units, the buffer rooms, and the holding mechanism unit, the presence of the process subject member, and a process state thereof, the control unit having: a section that selects a transport algorithm from among transport algorithm judgment rules that are obtained by simulating in advance a plurality of transport algorithms for controlling transportation of the process subject member for each condition of a combination of the number and arrangement of the process chambers and process time of a process subject member based on the device state information and process time of the process subject member; and a section that computes a transport destination of the process subject member based on the selected transport algorithm.
