  • Patent number: 7090741
    Abstract: A semiconductor processing system includes a common transfer chamber (34) having first and second compartments (46, 48) partitioned by a partition wall (44). First and second vacuum processing apparatuses (32E, 32A) are respectively connected to the first and second compartments (46, 48). A pressure control section (PCS) controls the pressures inside the first and second compartments (46, 48). The pressure control section (PCS) includes first and second vacuum pumps (68, 70) respectively connected to the first and second compartments (46, 48), and a line (76) connecting the delivery side of the second vacuum pump (70) to the suction side of the first vacuum pump (68). The pressure control section (PCS) performs a setting such that a second ultimate pressure or lowest operational pressure of the second compartment (48) is lower than a first ultimate pressure or lowest operational pressure of the first compartment (46).

  • Patent number: 6802934
    Abstract: Two load lock chambers 130 and 132 are arranged between a first transfer chamber 122 and a second transfer chamber 133. Each of the load lock chambers is capable of accommodating a single wafer W. The first transfer chamber 122 is provided with a first transfer unit 124 having two substrate holders 124a, 124b each capable of holding a single object to be processed, in order to transport the wafer W among a load port site 120, the first load lock chamber 130, the second load lock chamber 132 and a positioning unit 150. The second transfer chamber 133 is provided with a second transfer unit 156 having two substrate holders 156a, 156b each capable of holding the single object to be processed, in order to transport the wafer between the first load lock chamber 130, the second load lock chamber 132 and respective vacuum processing chambers 158 to 164. Since the volume of each load lock chamber can be minimized, it is possible to perform the prompt control of atmospheres in the load lock chambers.
