[labnetwork] PDMS mold process?

[vsoares at inesc-mn.pt]

Hi Russ,

 

We make PDMS molds in our lab but we have banned it from the cleanroom. It
tends to stick everywhere and since it's transparent, you often don't notice
it until it's too late. We have had pieces sticking on the bottom of wafers.

So now the molds are made outside the cleanroom inside a laminar flow hood.

Subject: [labnetwork] PDMS mold process?

 

Is anyone familiar with PDMS (or other material) mold fabrication? Any
procedures or gotchas to worry about? 

 

Bio faculty member asking if we can make molds in our fab. I only know how
to make semiconductor, photonic, and quantum devices. 

 

Thanks!

 

Russ
