SUMMARY
The discussion centers on the mechanical stability of SU-8 pillars during the spincoating process of PDMS wells, specifically 50 µm in diameter and 100-200 µm deep. It is established that the SU-8 pillars can maintain their integrity if proper adhesion to the wafer is ensured, as poor adhesion can lead to pillars detaching during unmolding. Additionally, high-speed spinning may result in the loss of pillars, raising questions about the necessity of fast spinning in the context of creating wells rather than through-holes in PDMS.
