I did a write last Sunday using Raith. The focusing and write field 
alignment all went through without any problems. After I developed and 
etched the sample, I realized that the mask and the actual patterns that 
were written by Raith differed. I'm attaching optical microscope 
pictures from the sample I etched and also parts of the mask that I used 
for EBL. If you ever experienced similar problems with Raith 
(writefields intersecting with one another, EBL results different than 
the mask results etc.) please let me know. I have other sessions coming 
up, and since I'm doing multi-layer EBL, I cannot continue if the first 
layer is messed up.

Thanks a lot,
