  • Publication number: 20250046572
    Abstract: A method for operating a plasma chamber to increase ion energy and decrease angular spread of ions during an etch operation is described. Method includes placing a substrate on an electrostatic chuck within the plasma chamber, wherein the electrostatic chuck is electrically coupled to a node. Method further includes forming a plasma in the plasma chamber, where the plasma produces a sheath with a first sheath voltage. The method further includes increasing the first sheath voltage to a second sheath voltage by applying a non-sinusoidal voltage at the electrostatic chuck and by applying a sinusoidal voltage at the electrostatic chuck, where a sum of the non-sinusoidal voltage and the sinusoidal voltage creates a voltage response on the electrostatic chuck that effectuates a change in a spread in ion energy at the wafer.
