You are using KOH etching to define a 200 um thru-hole in a
<100> wafer. What should the dimensions on your mask be if
you are using a: a) 400 um thick wafer b) 600 um wafer. What would
be the dimensions of the thru-hole be if you used the mask intended
for the 400 um thick wafer on the 600 um thick wafer?
Thank you in advance!
