Abstract

See full text

An extreme ultraviolet (EUV) mask is received. The EUV mask has an EUV pellicle disposed thereover. The EUV pellicle is coupled to the EUV mask at least in part via glue that is disposed on the EUV mask. The EUV pellicle is removed, thereby exposing the glue. A localized glue-removal process is performed by targeting a region of the EUV mask on which the glue is disposed. The localized glue-removal process is performed without affecting other regions of the EUV mask that do not have the glue disposed thereon. The localized glue-removal process may include injecting a cleaning chemical onto the glue and removing a waste chemical produced by the cleaning chemical and the glue. The localized glue-removal process may also include a plasma process that applies plasma to the glue. The localized glue-removal process may further include a laser process that shoots a focused laser beam at the glue.
