    摘要: A radio frequency (RF) glow discharge plasma etch electrode design is disclosed which is capable of creating high power density plasma with uniform etch rates, while providing access for automatic loading semiconductor wafers from outside of the plasma region. The electrode assembly comprises of an electrode to which RF energy is applied surrounded by an insulator, which in turn surrounded a grounded surface all of which have cylindrical symmetry. When placed a small distance from a flat, grounded substrate, the electrode assembly creates a volume which can effectively combine a high power density plasma, while maintaining a sufficient channel for pumping a gas flow and for observing the plasma optically. The same channel is widened for automatic transport of semiconductor wafers from outside of the plasma reactor chamber. Such confined high power density plasma are important for high rate, uniform, anisotropic etching, especially for silicon dioxide.

    摘要: An apparatus for reactive ion etching or plasma etching wherein the wafer faces downward. The process gas is supplied through a distributor which is below the wafer and has orifices pointing away from the wafer. The vacuum (exhaust) port is below the distributor, so that there is no bulk gas flow near the face of the wafer. Preferably transport of the process gasses and their products to the face of the wafer is dominated by diffusion.

    摘要: A fluorine based metal etch chemistry, wherein an admixture of etch products (or species which are closely related to etch products) is added during the post etch stage, i.e. during the stage when the pattern has partially cleared by overetch is not yet completed, to maintain the balance of chemistries which provides selectivity and anisotropy. In a tungsten etch, WF.sub.6 is usefully added during the post etch period to provide this loading.
