Abstract

A bias supply system and methods are disclosed. The bias supply system comprises an output node, a return node, and a bias supply configured to apply an asymmetric periodic voltage waveform between the output node and the return node. A variable capacitance is coupled between the output node and the return node, and a controller is coupled to the variable capacitance. The controller is configured to receive a setting that defines a slope of a workpiece voltage, monitor electrical parameters at the output node to obtain an indication of an actual slope of the workpiece voltage, and control the variable capacitance so the actual slope of the workpiece voltage approaches the slope defined by the setting.
