Radio frequency processing apparatus and method

Abstract:

In an embodiment, an apparatus includes a radio frequency (RF) generator that is to generate a RF signal, first and second electrodes, and an impedance match module in series between the RF generator and the first electrode. The RF generator detects reflected power from the RF signal applied to a load electrically coupled between the first and second electrodes to change a temperature of the load, the RF signal to be applied to the load until the reflected power reaches a particular value.
