Looking to spin coat a 'binder' on a wafer, need approval to bring chemical into SNF

Hi Nathan --

Thanks for the info -- the spin coater in the saw room is definitely the 
right place to do this - and thanks for storing in your own lab.  A 
couple of questions.  First, will you be diluting or mixing this 
material?  If so, with what?  Also, I'm a little concerned that some of 
the chemicals may be absorbed in the teflon housing.  Mahnaz has found 
that there are liners for the coater bowl -- could you please follow up 
with her about them?  Or we might brainstorm ideas on how to line the bowl.

There's a programmable hot plate in the saw room -- we'll just need to 
make sure it's under the hood when you use it (I can show you how to set 
it up.)

Please get in touch with Mahnaz or me to show you how to use the coater.
