WebEtching is a critically important process module, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching. In some cases, the masking material is a photoresist which has been patterned using photolithography.

The SU-8 photoresist baking is carried out two or three times during the whole process and each bake has different meanings. The first photoresist bake is called soft bake; it’s done just after the spin coating of the SU-8 photoresist. Its aim is to evaporate the solvent to make the ...
