    摘要: Methods for fabricating devices having small feature sizes are provided. In an exemplary embodiment, a method comprises forming a patterned first mask layer overlying a subject material layer and isotropically etching the patterned first mask layer. A second masking layer is deposited overlying the patterned first mask layer and the isotropically-etched patterned first mask layer is exposed. The isotropically-etched patterned first mask layer is removed and the subject material layer is etched to form a feature therein.

    摘要: A method for treating an edge portion of a wafer with a plasma or select chemical formulation in order to enhance adhesion characteristics and inhibit delamination of a layer of material from the wafer surface only on the edge portion that is being treated. Alternatively, the method may be utilized to effectuate a cleaning of an edge portion of a wafer.
