摘要: Some embodiments include methods and systems for wafer biasing in a plasma chamber. A method, for example, may include: generating a first high voltage by a first pulsed voltage source using DC voltages and coupling the first high voltage to a wafer in the plasma chamber via at least one direct connection, the at least one direct connection enabling ion energy control in the plasma chamber; generating one or more of low and medium voltages by a second pulsed voltage source; coupling, capacitively, the one or more of low and medium voltages to the wafer; and pulsing the first high voltage and the one or more of low and medium voltages to achieve a configurable ion energy distribution in the wafer.

摘要: Some embodiments of the invention include a thruster system comprising a thruster and a pulsing power supply. The thruster may include a gas inlet port; a plasma jet outlet; and a first electrode. In some embodiments, the pulsing power supply may provide an electrical potential to the first electrode with a pulse repetition frequency greater than 10 kHz, a voltage greater than 5 kilovolts. In some embodiments, the pressure downstream from the thruster can be less than 10 Torr. In some embodiments, when a plasma is produced within the thruster by energizing a gas flowing into the thruster through the gas inlet port, the plasma is expelled from the thruster through the plasma jet outlet.
