Spin coating method for membrane fabrication
WebThe wafers would be used as masters for porous PDMS membrane fabrication via spin coating. Since I'm trying to make my PDMS porous, I would need the silicon wafers to have micropillars consisting of 3 um diameters and a density of 8e5 pillars per cm2. If making the wafers with the micropillars is possible, I'd love to try two iterations of wafers.
