Hi Guru,

Structured by Uv...first negative photoresist that can produce very high aspect ratio Structures.

.. and Furthermore compared to simple thin resist , the SU8 once STRUCTURED by near UV can be kept definitely as a permanant structure... for instance in bio MEMS or MiCro Fluidic.

I'd like to share an interesting forum having nearly 100 questions on SU-8:

In addition to UV lithography, I have also seen structuring of SU-8 2002 by electron beam lithography.
