A plasma processing apparatus including: a chamber configured to provide a space for processing a substrate; a substrate stage configured to support the substrate within the chamber and including a first electrode, the first electrode configured to receive a first radio frequency signal; a second electrode disposed on an upper portion of the chamber to face the first electrode, the second electrode configured to receive a second radio frequency signal; a gas supply unit configured to supply a process gas onto the substrate within the chamber; and a thermal control unit configured to circulate a heat transfer medium through a first fluid passage provided in the first electrode and a second fluid passage provided in the second electrode to maintain the first and second electrodes at the same temperature.
CONTROL APPARATUS AND CONTROL METHOD FOR FILM FORMING APPARATUS
A control apparatus is included in a film forming apparatus that includes: a rotation table disposed in a vacuum container and configured to rotate around a central shaft of a table surface, thereby revolving a substrate on a disposing surface provided on a part of the table surface; a stage configured to rotate around the central shaft of the disposing surface, thereby rotating the substrate on the disposing surface; and a gas supply unit configured to supply a gas into the vacuum container. The control apparatus includes: a display control unit configured to display a setting screen for setting a first parameter that controls a rotation of the substrate; and a process execution unit configured to form a film on the substrate while controlling the rotation of the substrate based on the set first parameter.
PULSING PLASMA TREATMENT FOR FILM DENSIFICATION
Methods and apparatus for forming a barrier layer are provided herein. In some embodiments, a method of forming a barrier layer on a substrate includes treating an exposed layer deposited on a substrate and within a feature of the substrate by pulsing a bias power applied to a substrate support supporting the substrate while exposing the layer to a plasma. The exposed layer can be deposited by an atomic layer deposition process, and can be, for example, a tantalum nitride layer. The bias power can be up to 500 watts of RF power at a pulse frequency of about 1 Hz to about 10 kHz. The bias power can be pulsed uniformly or at multiple different levels.
MAGNETICALLY COUPLED RF FILTER FOR SUBSTRATE PROCESSING CHAMBERS
A semiconductor processing chamber for processing semiconductor substrates may include a pedestal to support a substrate with a heater zones and a wire mesh configured to deliver a Radio Frequency (RF) signal to a plasma. The chamber may also include heater zone controls that deliver current to the heater zones and a filter circuit between the heater zone controls and the heater zones. The filter circuit may include inductors on leads from the heater zones and a resonant circuit with a resonant inductor that is magnetically coupled to the lead inductors. The resonant circuit may produce a resonant peak that filters the RF signal delivered to the wire mesh from the leads from the heater zones to prevent the RF signal from reaching the heater zone controls.
CHUCKING PROCESS AND SYSTEM FOR SUBSTRATE PROCESSING CHAMBERS
The present disclosure relates to methods and systems for chucking in substrate processing chambers. In one implementation, a method of chucking one or more substrates in a substrate processing chamber includes applying a chucking voltage to a pedestal. A substrate is disposed on a support surface of the pedestal. The method also includes ramping the chucking voltage from the applied voltage, detecting an impedance shift while ramping the chucking voltage, determining a corresponding chucking voltage at which the impedance shift occurs, and determining a refined chucking voltage based on the impedance shift and the corresponding chucking voltage.
SUBSTRATE PROCESSING METHOD AND APPARATUS
