    摘要: Provided is a negative ion irradiation device in which an object is irradiated with a negative ion. The device includes a chamber that allows the negative ion to be generated therein, a gas supply unit that supplies a gas which is a raw material for the negative ion, a plasma generating portion that generates plasma, a voltage applying unit that applies a voltage to the object, a control unit that performs control of the gas supply unit, the plasma generating portion, and the voltage applying unit. The control unit controls the gas supply unit to supply the gas into the chamber, controls the plasma generating portion to generate the plasma in the chamber and to generate the negative ion by stopping the generation of the plasma, and controls the voltage applying unit to start voltage application during plasma generation and to continue voltage application after plasma generation stop.

    摘要: An apparatus for laser deposition with a reactive gas includes a source, a target, and a substrate. The source emits a plasma jet of the reactive gas. The target generates a plasma plume of a deposition material when a laser beam ablates the target. The substrate collects a film resulting from a chemical reaction between the deposition material from the plasma plume and the reactive gas from the plasma jet. Correspondingly, a method for laser deposition with a reactive gas includes steps of emitting a plasma jet of the reactive gas, ablating a target with a laser beam, and collecting a film on a substrate. The plasma jet emits from an orifice of a source. Ablating the target generates a plasma plume of a deposition material. The film results from a chemical reaction between the deposition material from the plasma plume and the reactive gas from the plasma jet.

    摘要: A method for cleaning contacts on a substrate incorporates ion control to selectively remove oxides. The method includes exposing the substrate to ions of an inert gas, supplying a first RF frequency of a first bias power supply to a substrate support, supplying a second RF frequency of a second bias power supply to a substrate support, and adjusting a first power level of the first RF frequency and a second power level of the second RF frequency to selectively remove oxide from at least one contact on the substrate while inhibiting sputtering of polymer material wherein the oxide removal is selective over removal of polymer material surrounding the at least one contact.
