Hi All,
I am using a photoplotted transparency mask to pattern resist for a lift off
process. I have a series of lines I have exposed. See image:

Looking at the pattern under the microscope indicates that there is no sharp
edge on the corner. I have used AZ6632 positive resist. To me this doesn't look
like it will be successful with lift off.
This lines are smallest to largest 10,20,30..um.
Any suggestions or thoughts on:
-Whether lift off will occur.
-What could be the problem. Resist, Exposure Time, Baking, Proper Contact with
substrate?
Looking forward to hearing from you regarding this.
Cheers,
Darren
