Patent ID: 8282984

Claim:
A processing condition inspection method of a damage recovery process for reforming a film containing OH group generated by damages from an etching or an ashing process, comprising: preparing a substrate having a resist film containing an OH group; measuring an initial film thickness of the resist film; performing a damage recovery process on the resist film by using a processing gas containing a silylation agent after measuring the initial film thickness, wherein a film thickness of the resist film is increased after performing the damage recovery process; measuring a film thickness of the resist film after the damage recovery process; calculating a film thickness difference of the resist film before and after the damage recovery process; and determining, based on the film thickness difference, whether a processing condition of the damage recovery process performed by using the processing gas containing the silylation agent is appropriate or inappropriate for reforming the film containing OH group generated by damages from the etching or ashing process, wherein said determining includes determining whether an amount of increased film thickness of the resist film after the damage recovery process is within a tolerance range.
