Hi,

I can't give you much advice on solvents but I can tell you that you'll need
very small chain lengths to make a 20nm film, my first guess is a molecular
weight below 10K.  Have you considered photopolymerization as a route to the
thin films?  PMMA shouldn't be difficult to achieve this way.


Good luck,
Matt

Subject: Spam:[mems-talk] Polymer solutions to be coated by spin coater


Dear MEMS researcher,


I wish to coat several polymer solutions on the silicon substrate
by spin coater.  It is to make a research for the measurement of thermal
conductivity of thin polymer film.

The thickness is 2 micro m, 200 nm, 20 nm for each film.

The polymer films are poly(ethylene terephthalate), polycarbonate, and PMMA.

Does anybody know what kind of solvent is proper for each polymer, and what
concentration is proper for those thickness?

Thank you very much.
Sincerely

Ickchan Kim
