Abstract:
In one embodiment, a semiconductor processing tool includes a plasma chamber and an impedance matching circuit. The matching circuit includes a first electronically variable capacitor having a first variable capacitance, a second electronically variable capacitor having a second variable capacitance, and a control circuit. The control circuit is configured to determine a variable impedance of the plasma chamber, determine a first capacitance value for the first electronically variable capacitor and a second capacitance value for the second electronically variable capacitor, and generate a control signal to alter at least one of the first variable capacitance and the second variable capacitance to the first capacitance value and the second capacitance value, respectively. An elapsed time between determining the variable impedance of the plasma chamber to when RF power reflected back to the RF source decreases is less than about 150 μsec.

Claim (Index 2):
A method of matching an impedance, the method comprising:\n determining, by an impedance matching circuit, a variable impedance of a plasma chamber, the impedance matching circuit comprising an RF input operably coupled to an RF source, an RF output operably coupled to the plasma chamber, a first electronically variable capacitor having a first variable capacitance, and a second electronically variable capacitor having a second variable capacitance; determining a first variable capacitance value for the first electronically variable capacitor and a second variable capacitance value for the second electronically variable capacitor, for creating an impedance match at the RF input of the impedance matching circuit; and altering at least one of the first variable capacitance and the second variable capacitance to the first capacitance value and the second capacitance value, respectively, wherein an elapsed time between determining the variable impedance of the plasma chamber to when RF power reflected back to the RF source decreases is less than about 150 \u03bcsec.
