Abstract:
A voltage-current sensor enables more accurate measurement of the voltage, current, and phase of RF power that is delivered to high-temperature processing region. The sensor includes a planar body comprised of a non-organic, electrically insulative material, a measurement opening formed in the planar body, a voltage pickup disposed around the measurement opening, and a current pickup disposed around the measurement opening. Because of the planar configuration and material composition of the sensor, the sensor can be disposed proximate to or in contact with a high-temperature surface of a plasma processing chamber.

Claim (Index 19):
A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform the steps of:\n causing RF power to be generated at a first magnitude and transmitted to a plasma processing chamber via a transmission line fed through a measurement opening formed in a planar body of a sensor, wherein the sensor is mounted on or coupled directly to the plasma processing chamber; receiving a first voltage signal from a voltage pickup disposed around the measurement opening and a second voltage signal from a current pickup disposed around the measurement opening, wherein the first voltage signal and the second voltage signal are generated in response to the RF power being transmitted via the transmission line; determining an actual RF power coupled to the plasma processing chamber, based on the first voltage signal, the second voltage signal, a first calibration coefficient that is applied to the first voltage signal, and a second calibration coefficient that is applied to the second voltage signal; determining that the actual RF power coupled to the plasma processing chamber is outside a predetermined range of a target RF power; and responsive to determining the actual RF power is outside the predetermined range, causing RF power to be generated at a third magnitude and transmitted to the plasma processing chamber via the transmission line.
