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..

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. > > Cheers, Marie > > > > _______________________________________________ > MEMS-talk@memsnet.org mailing list: to unsubscribe or change your list > options, visit http://mail.mems-exchange.org/mailman/listinfo/mems-talk > Hosted by the MEMS Exchange, providers of MEMS processing services. > Visit us at http://www.memsnet.org/ >
