Hello, could you give me more information about KMER resist ? Do you have also more information about using H3PO4 with resist. In your mail, I don't find the e-mail of this indian guy (-Ashutosh-) who said that resist resits to H3PO4. I would like to have more information about this process. Because, usually I use boiling H3PO4 to etch Si3N4 and resist don't stand it. best regards Danick Briand
