# Stability of SU-8 Pillars

## Main Question or Discussion Point

I am trying to make PDMS wells (50 um diameter, 100-200 um deep) and was considering using a SU-8 mould fabricated by lithography. This would however mean that I would be making 50um diameter/100-200 um high pillars. I am unsure about the mechanical stability of this system. Will the pillars hold during spincoating of PDMS?
