BCB/polyimide process

[James Harris]

Mathilde,
Hong Liu, one of my former students did some form of polyimde 
planarizing for high speed modulators.  You should look at her thesis 
for possible recipes and if you don't see what you need, I can 
contact her and she is still local, so might even be able to come bye 
some afternoon/evening and look at what you are doing and make 
suggestions.  The other former student who might have useful ideas is 
Chien Chung Lin and he is also still local.  Let me know if you would 
like me to contact any of these people or you need their theses.
