Dear Colleagues,
We are doing some CO2 critical point drying of silicon structures. Not getting a
very good yield, the question came up: what protocol do you use?
I did some googling, and found three distinctly different protocols (at least).
1. Multiple exchanges: 120 cycles totaling approx. 15 minutes
2. A number of exchanges: 5-10 cycles totaling approx.. 30 minutes
3. One-two exchanges: 1-2 cycles totaling approx. 1,5-2 hours
I guess it comes down to the question: what works better in your application?
"Series dilutions" or "molecular transport through diffusion"
I would happily read a few lines on your results and experiences ;-) on the
matter. It would be neat to get a better understanding of the scenarios where
this or that works better.
