Plasma treatment method to improve photo resist roughness and remove photo resist scum

A patterned photo resist layer (for example an EUV photo resist layer), which may exhibit line width roughness (LWR) and line edge roughness (LER) or scum is treated with a plasma treatment before subsequent etching processes. The plasma treatment reduces LWR, LER, and/or photo resist scum. In one e...
