[mems-talk] Cutting chips with fragile free-standing devices into small pieces

Hi,

never faced this problem just got a idea during reading your text.
Dependent on your kind of structure, you might try to packaging the 
whole structure with a photoresist or something like this.

Then you can handle your structure, store them easily etc. and just if 
you need them dissolve the protecting layer.

However, its hardly depends on the other materials on your chip and on 
the geometry.

Just a two cents idea ;)

Bye
Torsten
