Hi all --

Sorry, I was wrong -- it's not a film on silicon, but crystalline
material.  What do you think?

 Hi Mary, I attached MSDS for lithium tantalate, which is on SNF MSDS
file as well.  The wafer is lithium tantalate (LiTaO3) and no film is on
that.  Lithium Tanalate is very stable upto 1200C or higher.  Let me
know if you have more question. Thanks,Lan

     Hi Lan --

     Do you have more information about your wafers and material?
     Are they silicon-based?  Do you wafers contain any other
     unusual films?  We'd like to make sure that any material that
     goes into tylan4 does not volatilize or degrade at processing
     temperature.  Do you have any information about the behavior
     of lithium tantalate under these conditions?
