Hi Elina, If your substrate is single crystal silicon, you can try the so-called "stealth dicing" developped by Hamamatsu photonics. In this method, you produce crystal defects using IR-laser WITHIN the substrate. The chip separation is done by stretching the dicing tape subsequently. This method is free of water, dust, mechanical stress and edge chipping, thus ideal for dicing the chips with fragile structures like cantilevers or membranes. For more info, see the link below. http://jp.hamamatsu.com/products/semicon-fpd/pd393/L9570-01/index_en.html Best regards, Natsuki -----Ursprüngliche Nachricht----- Von: mems-talk-bounces@memsnet.org [mailto:mems-talk-bounces@memsnet.org] Im Auftrag von Ir.

I have wafers with cantilever that need to be sowing to obtain the single die. I tried with one but all the cantilever do not survive because of the water flushing on the wafer Do anyone have experience with the sowing of the wafer with cantilever?
