Hi Marie,

thanks a lot for your advice, but it would not work in my case I guess.. the
sample is only supposed to be about 20 um thick and the resist hight is over
1 mm. even if I would manage to cut the wafer with 20 um precision, cleaving
it after with 1 mm resist on top of it would be impossible.

Any other suggestions? there must be a way how to do it, there are so many
samples which have to be investigated such a way and they are often even
more tough and larger that mine..

J-

I use a normal dicing saw but only cut partially through the wafer on the
backside.  Then do my normal spinning, etc. for photo-litho.  When I want to
break the wafer later on the fracture lines are already defined.  I like
this technique because all of the mess and heat of dicing is done with
before any of the photo-litho.
