    摘要: A process for manipulating particles distributed substantially non-uniformly in a plasma of a carrier or reaction gas, wherein Coulomb interaction between the particles is so low that the particles substantially do not form a plasmacrystalline state, and the particles are exposed in a location-selective manner to external adjustment forces and/or the plasma conditions are subjected to a location-selective change to apply at least a portion of the particles onto a substrate surface mask-free and/or subject it to a location-selective plasma treatment in the carrier or reaction gas.

    摘要: The metastable atom bombardment source provides a charged particle free beam of metastable species that can be used to bombard and ionize organic and inorganic substances in a gas phase. The metastable atoms are produced by inducing a discharge in a gas (rare gases or small molecules). The discharge is curved between the cathode and anode, with the cathode located in a medium pressure zone and the anode located off-axis in a low pressure zone. A nozzle located between the cathode and the anode provides a collimated beam of metastable atoms of low kinetic energy that is directed at an ion volume containing the substances to be analyzed. By selecting the energy of the metastable state, selective fragmentation of molecules, particularly large molecular weight molecules, can be carried out.

    摘要: A phase detector which determines the phase based upon the output signals from a power coupler. The power coupler outputs a first signal and a second signal. The first and second signals are input to a magnitude detector which determines the magnitude of the relative phase between the first and second signals. The first and second signals are also input to a sign discriminator which determines the sign of the phase between the first and second signals.

    摘要: The present invention generally provides a method for processing a semiconductor substrate, wherein the method includes positioning a substrate in a processing chamber having at least a first and second coils positioned above the substrate and supplying a first electrical current to the first coil. The method further includes supplying a second current to the second coil and regulating a current ratio of electrical current supplied to the first and second coils with a power distribution network in communication with the first and second coils and a single power supply. The method may further include controlling plasma uniformity in a semiconductor processing chamber, wherein the control process includes positioning a first coil above the processing chamber, the first coil being concentrically positioned about a vertical axis of the processing chamber, and positioning a second coil above the processing chamber, the second coil being concentrically positioned about the vertical axis of the processing chamber and radially outward from the first coil. The control process may further include supplying electrical power to the first and second coils with a single power distribution network to selectively regulate a magnetic field intensity generated by the first and second coils above a workpiece in the processing chamber.
