Hello, All,
I have a question on the difference between AZ400k and AZ300MIF developer
used for AZP4620 photoresist. The official website
http://www.az-em.com/products/na/photoresists/thick_film.html shows the
developer is AZ300MIF, but I heard many people are using AZ400k developer.
Anyone can help me out on this, thanks
Michael
