Claim 7:
8. A pulsed direct current (DC) power delivery system, comprising:
a main pulser configured to deliver DC pulse waveforms to a main pulser output; and
a power module electrically coupled to the main pulser output of the main pulser, the power module configured to control an ion energy distribution function of ions within a formed plasma, the power module comprising:
a voltage source or a current source, wherein the voltage source or current source is configured to be electrically coupled between the main pulser output and an electrode within a processing chamber, and wherein the voltage source or the current source comprises a DC current source or a shaped DC pulse voltage source or a DC voltage source electrically coupled in series to a resistor; and
a switch electrically coupled in parallel to the voltage source or the current source.
