Webple, using phosphoric acid as a component of typical Al-etching mixtures, dissolves a few nm thick native aluminium oxide ﬁ lm present on aluminium surfaces. For this reason, photoresist processing also impacts a subsequent Al etching step: The alkaline developers preferentially dissolve the native aluminium oxide layer where the re- WebNitric acid first reacts with the surface of the aluminum parts forming an aluminum oxide coating. Phosphoric acid is then added to attack this oxide coating forming aluminum phosphate, which congregates in microscopic recesses on the surface of the part. This action serves to protect the recessed areas from additional phosphoric acid attack.
