    摘要: A surface wave coupled plasma etching apparatus according to the present invention can produce a plasma within a confined area above an etching object by a microwave confinement plate, so as to prevent an upper portion of the apparatus from being sputtered by the plasma. The microwave confinement plate is interposed between a pair of glass plates, so that the microwave confinement plate is not exposed to and sputtered by the plasma during an etching process. The lower glass plate which protects the microwave confinement plate from the plasma is formed so as not to change a temperature of itself rapidly when the etching stops, and thereby an undesirable polymer adhesion to the lower glass plate is avoided.

    摘要: A method of etching a material film formed on a semiconductor wafer loaded onto a reaction chamber of a surface wave coupled plasma etching apparatus having an insulation plate which is capable of generating surface waves by microwaves, and a glass plate placed below the insulation plate, for transmitting the produced surface waves. In the method, the glass plate is rapidly pre-heated by generating an argon (Ar) or xenon (Xe) surface wave coupled plasma which has a high ion density and a large mass, and the material layer is then etched. Therefore, the preheating time of the glass plate can be sharply reduced to less than five minutes. Also, because the etching gas is not used for the heating of the glass, damage to the glass plate can be reduced and generation of polymer on the glass plate is suppressed with an improved etching efficiency, so that failure in etching can also be avoided.
