The cleavage of ether bonds has been , and still is, an important area of research in organic chemistry . Most current interest on ether cleavage stems from efforts towards valorization of wood and organic waste . Methods for ether cleavage include acid cleavage, alkali metal cleavage, nucleophilic cleavage, heterogeneous and homogeneous catalytic cleavage , electrochemical cleavage , and photochemical cleavage. Unfortunately, most procotols for ether cleavage are specific for small molecules with certain aryl or alkyl ethers including specific functional groups. It seems difficult to foresee how applicable these ether cleavage methods are in the case of highly polymerized SU-8, mostly due to the steric hindrance effects, as the dense polymer structure protects the sites of attack. After an extensive review of the current literature we have not found any successful application of these chemical ether cleavage methods for SU-8 removal. The method here reported was discovered accidentally after unsuccessfully attempting to lift off the resist with dimethylamine as a solvent, and subsequently immersing the sample in sulfuric acid.
