Upon exposure, it dissociates into nitrene and N 2. The nitrene reacts with the rubber molecules so that a cross linking between resin molecules occurs, becoming unsoluble.

Any variation of this formulation becomes a very similar resist, but as it is not exactly SU-8, the variations are called epoxy based resists. 47/56 Example: SU-8
