Thank you for updating your process flow to include the equipment you want 
to use.  I have a recommendation.  The feature size you are showing for 
your ebeam work is 200nm.  You may want to consider using the Hitachi ebeam 
system instead of the Raith.  200nm is compatible with the resolution of 
the Hitachi and you will be able to get trained quicker and the machine is 
not used as heavily as the Raith.

We also need to involve Jim McVitte concerning your etching.  I am not 
familiar with the gas chemistries needed to etch YBiFeO or YCeFeO 
films.  Do you know if you will need a fluorine or chlorine etch chemistry?
