Abstract:
A substrate processing system includes a vacuum transfer module; a plasma process module; a transfer robot in the vacuum transfer module; a stage in the plasma process module; a first ring disposed on the stage and a second ring disposed on the first ring to surround a substrate that is placed on the stage, the second ring having an inner diameter smaller than an inner diameter of the first ring; actuators to move support pins vertically to raise the first and the second rings and a transfer jig; and a controller configured to selectively execute a simultaneous transfer mode in which the transfer robot is caused to simultaneously transfer the first ring and the second ring and a sole transfer mode in which the transfer robot is caused to transfer only the second ring.
Abstract:
A mounting table includes a base and an electrostatic chuck provided on the base. The base has first and second top surface on which the electrostatic chuck and a focus ring are respectively provided. The second top surface is provided below the first top surface. A coolant path in the base has central and peripheral paths extending below the first and second top surfaces, respectively. The peripheral path has a portion extending along a side surface toward the first top surface. The mounting surface has central and peripheral regions. The mounting surface has protrusions formed in a dot shape. The protrusions are formed such that a contact area between the protrusions of the peripheral region and the backside of an object per unit area becomes greater than a contact area between the protrusions of the central region and the backside of the object per unit area.
Abstract:
Disclosed is an electrostatic chuck apparatus which is configured of: an electrostatic chuck section; an annular focus ring section provided to surround the electrostatic chuck section; and a cooling base section which cools the electrostatic chuck section and the focus ring section. The focus ring section is provided with an annular focus ring, an annular heat conducting sheet, an annular ceramic ring, a nonmagnetic heater, and an electrode section that supplies power to the heater.

Abstract:
A method which changes the temperature control range of a heater of a substrate processing apparatus. The temperature control range of a heater is changed or extended by changing the flow rate of the coolant flowing through a coolant channel from a first flow rate to a second flow rate which is smaller than the first flow rate, to change a first thermal conductivity of a mounting table to a second thermal conductivity which is smaller than the first thermal conductivity. The upper limit of the temperature control range is lower than the heat resistant temperature of a material of an adhesive of the mounting table.
