  • Patent number: 10818502
    Abstract: Systems and methods are disclosed for plasma discharge ignition to reduce surface particles and thereby decrease defects introduced during plasma processing. A microelectronic workpiece is positioned on a holder within a process chamber that includes a first radio frequency (RF) power source configured to couple RF power to a top portion of the process chamber, a second RF power source configured to couple RF power to the holder, and a direct current (DC) power supply. Initially, a process gas for plasma process is flowed into the process chamber. The process gas is ignited to form plasma by activating the second RF power source to apply RF power to the holder. Subsequently, the microelectronic workpiece is clamped to the holder by applying the positive voltage to the holder with the DC power supply, and the first RF power source is activated to maintain the plasma within the process chamber.

  • Patent number: 9945345
    Abstract: The invention provides a system and method for controlling corona discharge and arc formations during a single corona event, i.e. intra-event control. A driver circuit provides energy to the corona igniter and detects any arc formation. In response to each arc formation, the energy provided to the corona igniter is shut off for short time. The driver circuit also obtains information about the arc formations, such as timing of the first arc formation and number of occurrences. A control unit then adjusts the energy provided to the corona igniter after the shut off time and during the same corona event based on the information about the arc formations. For example, the voltage level could be reduced or the shut-off time could be increased to limit arc formations and increase the size of the corona discharge during the same corona event.

In the substrate, an electrode layer to which a direct current voltage for attraction is applied is embedded in a portion of the substrate, close to the attraction surface. In addition, a plurality of independent RF electrode layers to which different radio frequencies for plasma control are fed, respectively, are embedded in portions of the substrate, at an opposite side of the first electrode layer to the attraction surface. The RF electrode layers are arranged separately in different layers which are not on an identical plane in such a manner as to partially overlap each other in a plan view.

  • Patent number: 8270142
    Abstract: One embodiment of the present invention relates to a method for declamping a semiconductor wafer that is electrically adhered to a surface of an electrostatic chuck by a clamping voltage. In this method, the clamping voltage is deactivated. For a time following the deactivation, a first region of the wafer is lifted an first distance from the surface of the electrostatic chuck while a second region of the wafer remains adhered to the surface of the electrostatic chuck. A predetermined condition is monitored during the time. The second region is lifted from the surface of the electrostatic chuck when the predetermined condition is met.
