Hi all, I'm trying to suspend a beam structure with 150nm wide and 10um long with critical point drying process. However, our CPD equipment is very violent while introducing liquid CO2. After this process, all the suspended beams are gone. So I was wondering if there's a possible replacement of CPD process to suspend beam structures. I heard that people use some kind of low surface tension liquid and air dry the samples. Does anyone have experience on this? Any suggestion is appreciated. Thanks, Lin
