Betreff: [mems-talk] Finding [110] direction on (100) SOI wafer
Greetings everyone,
I would like to find out the exact [110] crystal direction of a (100) SOI wafer
before my first mask. The top Si (100) is about 200um thick. Wafer will come
with flat supposedly aligned to [110] direction, yet may have anyway from 0 to 3
degree alignment variation to [110]. Your suggestions would be greatly
appreciated.
Best regards,
