  • Publication number: 20020170677
    Abstract: Described are methods and apparatus for coupling RF power. In one embodiment, the method includes the step of flowing an RF current through an RF induction coil having a sufficiently large surface area and a low profile that results in effective RF power coupling to the load. Preferably, the turns of the coil comprise sheets of metal and the coil turns are substantially parallel to each other. Another aspect of the present invention is an apparatus for carrying out processes that use RF power.

  • Patent number: 6326584
    Abstract: RF power is delivered to a load in an RF power processor for carrying out process operations. The RF power delivery is performed using a variable frequency RF power amplifier and a control system. The control system maintains RF power delivery using control signals derived from reference RF signals used by the RF power amplifier and measurements of a characteristic of the RF power. The magnitude of the delivered RF power is controlled using measurements of the power input to the RF power amplifier.

  • Patent number: 6291938
    Abstract: Plasma processing is carried out in an apparatus having improved stability and reliability for plasma ignition. The improved plasma ignition characteristics result from a modified RF induction coil. One or more nonresonant sections have been added to the RF power induction coil. The nonresonant sections generate enhanced electric fields for igniting the plasma.

  • Patent number: 6168690
    Abstract: The invention relates to an improved sputter target that is a combination sputter target and induction antenna. In one embodiment, when the sputter target is energized sputter material particles are sputtered away from the sputter target and a plasma is induced. In another embodiment, the sputter target is energized by an energy source. In yet another embodiment, the energy source includes a bias power supply and an induction power supply. The bias power supply applies a potential to the sputter target relative to an object. The induction power supply applies a current to the sputter target. The potential and the current promote the sputtering away of the sputter target, the formation of the plasma and the anisotropic distribution of the sputtered material particles.

  • Patent number: 6156667
    Abstract: The reliability of a plasma processing chamber has been increased using a heat moderating material to facilitate controlling heat removal from dielectric parts of the plasma chamber. The heat moderating material performs at least one of the functions: moderating heat transfer rate and functioning as a heat spreader. The heat moderating material allows removal of heat from the dielectric so that the dielectric maintains temperatures that result in negligible corrosion to the dielectric and the dielectric maintains temperature gradients that minimize thermal stress induced breakage of the dielectric.

  • Patent number: 5889252
    Abstract: An arrangement and method for matching a load and a power source, such as an r.f. power source for a vacuum plasma processing chamber, includes a match network coupled between the power source and the load. The match network has at least two controllably variable electrical characteristics. A sensor is provided that senses at least two parameters of the load. A drive controller responds to the sensed parameters of the load to independently control varying a first one of the electrical characteristics of the match network as a function of only one of the parameters of the load, and a second one of the electrical characteristics of the match network as a function of another one of the parameters of the load. This is done until the power source and the load are in a matched condition. The separation of the match variables to establish a nearly one-to-one correspondence with the load parameters allows independent adjustment of the match variables to provide fast and unambiguous reaching of the matched condition.
