  • Publication number: 20220223384
    Abstract: An apparatus for manufacturing a semiconductor device may include a vacuum chamber, an electrostatic chuck (ESC), a cooler, an RF plate, a casing, a base plate and a gas supplier. The ESC may be arranged in the vacuum chamber. The cooler may be configured to cool the ESC. The RF plate may be arranged under the cooler. The casing may be configured to support the cooler. The base plate may be opposite to the RF plate to form an inner space together with the casing. The gas supplier may supply a gas having a low dew point to the inner space. Thus, a generation of the dew condensation at the very low temperature may be prevented so that a damage caused by a short, which may be generated by the dew condensation, may also be prevented.

  • Patent number: 8703002
    Abstract: A plasma processing apparatus includes a first radio frequency (RF) power supply unit for applying a first RF power for generating a plasma from a processing gas to at least one of a first and a second electrode which are disposed facing each other in an evacuable processing chamber. The first RF power supply unit is controlled by a control unit so that a first phase at which the first RF power has a first amplitude for generating a plasma and a second phase at which the first RF power has a second amplitude for generating substantially no plasma are alternately repeated at predetermined intervals.

  • Patent number: 7767055
    Abstract: A capacitive coupling plasma processing apparatus includes a process chamber configured to have a vacuum atmosphere, and a process gas supply section configured to supply a process gas into the chamber. In the chamber, a first electrode and a second electrode are disposed opposite each other. An RF power supply is disposed to supply an RF power to the first or second electrode to form an RF electric field within a plasma generation region between the first and second electrodes, so as to turn the process gas into plasma. The target substrate is supported by a support member between the first and second electrodes such that a process target surface thereof faces the second electrode. A conductive functional surface is disposed in a surrounding region around the plasma generation region and grounded to be coupled with the plasma in a sense of DC to expand the plasma.
