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 ...

WebPhotolithography Photolithography • Photo-litho-graphy: latin: light-stone-writing • Photolithography is an opt ical means for transferring patterns onto a substrate. It is essentially the same process that is used in lithographic printing. • Patterns are first transferred to an imagable photoresist layer. Web• ThPR dfidb h lih h l fhfild iThe PR patterns defined by photolithography are not permanent elements of the final device, but only replicas of the IC or MEMS features. To produce such features these PR patterns ... • The remaining image after pattern transfer can be used as a mask for subsequent process such as etching, ion implantation ...
