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.
