| 20110236591 | BIPOLAR RECTIFIER POWER SUPPLY - A process for powering an electrical load includes applying a rectified alternating current waveform across the load for a first time period with only a single power supply for at least two half cycles. At least one half cycle of an alternating current waveform of opposite polarity are then applied relative to the rectified alternating current waveform across the load for a second time period. Rectified alternating current waveform is then again applied across the load for at least two half cycles for a third time period to power the electrical load. The rectified alternating current waveform can be applied a direct current offset. A power supply is provided for provided power across the load according to this process. | 09-29-2011 |
| 20100207529 | CLOSED DRIFT ION SOURCE - A closed drift ion source is provided, having an anode that serves as both the center magnetic pole and as the electrical anode. The anode has an insulating material cap that produces a closed drift region to further increase the electrical impedance of the source. The ion source can be configured as a round, conventional ion source for space thruster applications or as a long, linear ion source for uniformly treating large area substrates. A particularly useful implementation uses the present invention as an anode for a magnetron sputter process. | 08-19-2010 |
| 20090032393 | Mirror Magnetron Plasma Source - A new and useful plasma source is provided, comprising at least one electrode connected to an alternating current power supply and disposed adjacent to a portion of a grounded substrate. The electrode has a center magnet that produces a magnetron plasma at the electrode when the electrode is biased negative by the alternating power supply, and a mirror plasma on the substrate when the electrode is biased positive by the alternating power supply. | 02-05-2009 |
