Abstract:
Systems and methods for providing a multi regime plasma wafer processing are described. The systems and methods have three states. During a first one of the states, an etching operation is performed. In a second one of the states, a power level of a kilohertz radio frequency signal is greater than zero to increase directionality of ions that are incident on a bottom surface of a stack layer. In a third one of the states, there is a reduction in a loss of mask on top of the stack layer and deposition may be performed.

Claim (Index 18):
A controller system for increasing directionality of ions of plasma towards a bottom of a stack layer, comprising:\n a processor configured to:\n control a kilohertz (kHz) radio frequency (RF) generator to generate a kHz RF signal having a power level for a first state, a power level for a second state, and a power level for a third state; \n control a megahertz (MHz) RF generator to generate a MHz RF signal having a power level for the first state, a power level for the second state, and a power level for the third state, \n wherein the power level of the MHz RF signal for the first state is lower than the power level of the kHz RF signal for the first state, \n wherein the power level of the MHz RF signal is approximately zero for the second state, \n wherein the power level of the MHz RF signal for the third state is less than the power level of the MHz RF signal for the first state and is greater than the power level of the MHz RF signal for the second state, \n wherein the power level of the kHz RF signal for the second state is lower than the power level of the kHz RF signal for the first state and the power level of the kHz RF signal for the second state is greater than the power level of the kHz RF signal for the third state to increase the directionality of the ions of the plasma towards the bottom of the stack layer for the second state; and \n a memory device coupled to the processor for storing the power levels of the kHz RF generator for the first, second, and third states and for storing the power levels of the MHz RF generator for the first, second, and third states.
