** For lift-off processes, we recommend resist thicknnesses ~5 times larger than the thickness of the metal to be lifted.

** For dry or wet etch processes, investiagte the etch rates in resist as this might limit the minimum thickness of your resist.

* '''Mask''': Design and order a photomask for your UV process. A detailed instruction on how to design and order a photomask can be found here.

* '''Substrate pretreatment''': In many processes it is recommended to pretreat your wafer before spin-coating. In some spin-coaters, these pretreatment processes are included in the spin coating of resist. If you use either the '''RCD8, SSE or a manual spin coater''', you should book equipment for pretreatment prior to spin  coating.
