    摘要: Embodiments of the disclosure may provide a matching network for physical vapor deposition. The matching network may include a first RF generator coupled to a deposition chamber target through a first impedance matching network having a first tuning circuit. The first RF generator may be configured to introduce a first AC signal to the deposition chamber target. The matching network may also include a second RF generator coupled to a deposition chamber pedestal through a second impedance matching network. The second RF generator may be configured to introduce a second AC signal to the deposition chamber pedestal. The first tuning circuit may be configured to modify an effect of the second AC signal on plasma formed between the deposition chamber target and the deposition chamber pedestal.

    摘要: A physical vapor deposition reactor includes a vacuum chamber with a sidewall, a ceiling and a retractable wafer support pedestal near a floor of the chamber, and a vacuum pump coupled to the chamber, the retractable wafer support pedestal having an internal electrode and a grounded base with a conductive annular flange extending from the base. A metal sputter target at the ceiling is energized by a high voltage D.C. source. The reactor has an RF plasma source power generator with a frequency suitable for exciting kinetic electrons is coupled to either the sputter target or to the internal electrode of the pedestal. A removable shield protects the sidewall and is grounded by plural compressible conductive tabs dispersed at generally uniform intervals on the annular flange and engaging a bottom edge of the shield whenever the retractable wafer support pedestal is in an unretracted position, each of the uniform intervals being less than a wavelength corresponding to the frequency of the RF plasma source power generator.

    摘要: Embodiments of the disclosure may provide a matching network for a physical vapor deposition system. The matching network may include an RF generator coupled to a first input of an impedance matching network, and a DC generator coupled a second input of the impedance matching network. The impedance matching network may be configured to receive an RF signal from the RF generator and a DC signal from the DC generator and cooperatively communicate both signals to a deposition chamber target through an output of the impedance matching network. The matching network may also include a filter disposed between the second input and the output of the impedance matching network.

The filter includes a set of reflection circuits coupled between the source power applicator and a ground potential and being tuned to, respectively, the bias frequency and intermodulation products of the bias frequency and the source frequency. The filter may further include a set of filter circuits coupled to the source power applicator and being tuned to, respectively, a second harmonic of the bias frequency and intermodulation products of the second harmonic of the bias frequency and the source frequency.
