Hi,
I read in various articles about negative and positive photoresists.
In order to create a hole in a photoresist, you need one of the following combinations:
Negative resist and Bright Field Mask
or
Positive resist and Dark Field Mask
I didn't manage to understand what're bright and dark field masks?
I know how negative and positive resists work.
Thanks for any help
