Abstract:
Systems and methods for multi-level pulsing of a parameter and multi-level pulsing of a frequency of a radio frequency (RF) signal are described. The parameter is pulsed from a low level to a high level while the frequency is pulsed from a low level to a high level. The parameter and the frequency are simultaneously pulsed to increase a rate of processing a wafer, to increase mask selectivity, and to reduce angular spread of ions within a plasma chamber.

Claim (Index 9):
The method of  claim 1 , wherein the rate of processing the substrate includes an etch rate, wherein during an occurrence of the first frequency level and an occurrence of the first parameter level, low energy ions are generated within the plasma chamber, wherein the first frequency level decreases a temperature of the low energy ions to decrease an angular spread of the low energy ions to increase mask selectivity, wherein the second parameter level, the third parameter level, and the second frequency level increases energy of the low energy ions to decrease the angular spread to increase the etch rate of etching the substrate, wherein the second parameter level and the third parameter level generates high energy ions within the plasma chamber to increase the etch rate of etching the substrate.
