    摘要: Variable mode plasma system and method for processing a semiconductor wafer. The modulation of the plasma potential relative to the semiconductor wafer is varied for different process steps. A capacitive shield may be selectively grounded to vary the level of capacitive coupling and modulation of the plasma. Process pressures, gases and power level may also be modified for different process steps. Plasma properties may easily be tailored to specific layers and materials being processed on the surface of the wafer. Variable mode processes may be adapted for (i) removal of photoresist after high-dose ion implant, (ii) post metal etch polymer removal, (iii) via clean, and (iv) other plasma enhanced processes.

    摘要: Plasma systems and methods for supplying activation energy to remove cross-linked photoresist crust using ion bombardment of the substrate from a plasma, at reduced temperature, achieved in part by operating the processing chamber at low pressures. Reduced temperatures prevent “popping” of the photoresist which can cause particulate contamination. The gas flow may comprise a principal gas, an inert diluent gas, and an additive gas. Principal gases for HDIS may comprise oxygen, hydrogen, and water vapor at pressures less than about 200 mTorr and a bias may be applied to the substrate support. When low-k dielectric material is present on vertical surfaces, reduced ion bombardment on vertical surfaces may be used, and a protective layer may be deposited on those surfaces.
