The radicals react with the resist to oxidize it to water, carbon monoxide, and carbon dioxide. The ashing step is usually done to remove the top layer or "skin" of the resist, then additional wet or dry etching processes can be used to strip away the remaining resist (see Etching). Some wet and dry chemical constituents are shown in Table 4 ...
