Hello Christian
A good compilation of SU-8 properties can be found at:
http://aveclafaux.freeservers.com/SU-8.html
The datasheets on Microchem's website give skeletal processing rules etc
that you can follow.

SU-8 is a good negative resist for high aspect ratio applications.
Using DRIE you can get almost vertical sidewalls.

A few papers that I found useful are listed below:
"High Aspect Ratio Ultrathick Negative Tone Near UV photoresist for mems
applications" - Despont,Brugger et al, IEEE 1997

"The Optimization and characterisation of Ultra-thick photoresist films"-
Flack et al SPIE 1998

"Micromachining applications of a high resolution ultrathick photoresist"
- LaBianca et al , J.Vac Sci Technology B, 1995

"Negative photoresists for optical lithography" - Shaw et al , IBM jrnl..

"Taguchi optimization for processing of EPON Su-8 resist" -Eyre et al,
IEEE 1998

Also read the two papers on improving process capability of SU-8 on the
Microchem website.

Hope this was useful.

Warm regards,
Samir Kagadkar
