Abstract: Embodiments are disclosed for reducing substrate breaks which result from inadequate de-chucking. Contaminants are removed from the surface of a chuck by exposing the chuck to a plasma process that comprises a hydrogen (H)-containing plasma. The chuck is subjected to the hydrogen-based plasma when no substrate is on the chuck. In one embodiment, the plasma is a hydrocarbon-based plasma. Hydrogen in the hydrocarbon plasma may react with and remove the contaminants. The process may further include an additional plasma step for removal of any newly formed materials that may result from the hydrocarbon plasma. The removal step may be, for example, a subsequent plasma ash step. In one embodiment, the chuck is an electrostatic chuck and the contaminants comprise fluorine. By removing contaminants from the chuck surface, improved substrate de-chucking occurs. This improvement correspondingly leads to less substrate breakage when removing substrates from the chuck.

Abstract: Embodiments of the present disclosure relate to a system for pulsed direct- current (DC) biasing and clamping a substrate. In one embodiment, the system includes a plasma chamber having an electrostatic chuck (ESC) for supporting a substrate. An electrode is embedded in the ESC and is electrically coupled to a biasing and clamping network. The biasing and clamping network includes at least a shaped DC pulse voltage source and a clamping network. The clamping network includes a DC source and a diode, and a resistor. The shaped DC pulse voltage source and the clamping network are connected in parallel. The biasing and clamping network automatically maintains a substantially constant clamping voltage, which is a voltage drop across the electrode and the substrate when the substrate is biased with pulsed DC voltage, leading to improved clamping of the substrate.
