摘要： A magnetron includes an anode cylindrical body, a plurality of vanes, a cathode filament, an input-side magnetic pole, an output-side magnetic pole, and a choke structure. The anode cylindrical body has a cylindrical shape with an input-side opening part and an output-side opening part. The plurality of vanes is radially disposed from a central axis of the anode cylindrical body to an inner wall surface of the anode cylindrical body. The cathode filament is disposed along the central axis of the anode cylindrical body. The input-side magnetic pole and the output-side magnetic pole are disposed on the input-side opening part and the output-side opening part, respectively. The choke structure is seamlessly formed and disposed so as to cover an opening rim of the input-side magnetic pole with respect to the central axis of the anode cylindrical body.

摘要： Magnetron, magnetron sputtering chamber, and magnetron sputtering apparatus are provided. The magnetron has a rotation center, and includes a first outer magnetic pole and a first inner magnetic pole of opposite polarities. The first outer magnetic pole has an annular structure around the rotation center. The first inner magnetic pole is located on the inner side of the first outer magnetic pole, and a first magnetic field track is formed between the first inner magnetic pole and the first outer magnetic pole. A straight line starting from the rotation center and along one of the radial directions passes through the first magnetic field track at least twice in succession, and the magnetic-field directions at the two positions of the first magnetic field track that the straight line passes through twice in succession are opposite to each other.

摘要： Pulsed radiation is generated at a power level that depends on a voltage level, frequency and duty cycle of a pulsed high voltage. A pulsing switch generates the pulsed high voltage from a high voltage and a pulse control signal. The pulsing switch has first and second bi-polar active switches connected in series between a high voltage conductor and a ground conductor. The pulsed high voltage is produced at a connection between the first and second bi-polar active switches when the first and second bi-polar active switches are repeatedly pulsed on and off to alternatingly connect the high voltage conductor and the ground conductor to a pulsed voltage output.
