An apparatus and method for controlling the plasma potential of a plasma within a plasma chamber (50) is disclosed. The apparatus and method utilize a Faraday shielded inductive source antenna (60) to generate the plasma within the plasma chamber (50) and an electrically conductive probe (100) that is inserted into the plasma chamber (50) to regulate the plasma potential. By independent biasing of the conductive probe (100), which regulates the plasma potential, the ion energy distribution at a conductive substrate (150) within the plasma chamber (50) may be controlled. |
