SU-8 is an epoxy based negative i-line photoresist  with a high contrast. More then 10:1 aspect ratio imaging with vertical sidewalls is one of the widely used properties of this resist. It also has high chemical, plasma and temperature resistance after curing which makes it well suited for permanent use applications.

In the cleanroom the SU-8 2000 product line is widely used, where the '''SU-8 2005''', '''SU-8 2035''', and '''SU-8 2075''' are supplied by Nanolab. Other resist formulations can be used, but has to be ordered by the user.
