摘要: A method of patterning a feature in a substrate to reduce edge roughness comprises forming a resist layer overlying a substrate, exposing the resist layer to create an image of a feature, and developing the exposed resist layer to leave a portion of the resist layer that creates the image of the feature. The method then includes treating the exposed resist layer with a plasma to cure the portion of the resist layer creating the feature image. The plasma treatment has an ion bombardment level insufficient to substantially etch the underlying substrate. The method then includes etching the underlying substrate to create the feature.
