Dear All,
I have etched 20-25 micron wide and 450-500 um deep holes in silicon
wafer by DRIE process. Now, i have to cut them along the center of the
holes so that i can take the SEM pictures of their cross section.
Right now, i am cutting them manually (by simple diamond cutter) but
till now i am not able to cut them perfectly.
Can any body suggest any method, how i can cut such deep holes along
the diameter.
