摘要： A plasma etching method for etching an object to be processed, which has at least an etching target layer and a patterned mask layer formed on the etching target layer, to form a recess corresponding to a pattern of the mask layer in the etching target layer, includes a first plasma process of forming deposits on the etching target layer at least around a boundary between the etching target layer and the mask layer in an opening portion constituting the pattern of the mask layer, and a second plasma process of forming the recess by etching the etching target layer after the first plasma process. An edge portion of an upper sidewall constituting the recess is rounded off in the second plasma process.

摘要： A dry etching method involves plasma etching an organic anti-reflecting coating film through a mask layer made of photoresist and having a predetermined pattern by using an etching gas of CF4 and O2. The method allows an organic anti-reflecting coating film to be etched such that the etched film exhibits a side wall portion having a better shape as compared with that formed by a conventional technique.
