Vapor drying for cleaning photoresists

摘要

One aspect of the present invention relates to a method of cleaning a patterned photoresist clad structure involving the steps of contacting the patterned photoresist clad structure with an alcohol vapor comprising at least one compound having the Formula ROH, wherein R is a hydrocarbon group comprising from 4 to about 8 carbon atoms; condensing the alcohol vapor on the patterned photoresist clad structure; and removing the condensed alcohol vapor from the patterned photoresist clad structure. Another aspect of the present invention involves the use of an alcohol vapor having a boiling point from about 102° C. to about 175° C. Yet another aspect of the present invention involves the use of an alcohol vapor having a flash point from about 15° C. to about 80° C.
