AZ® 111 XFS is a special photoresist with excellent adhesion on all surfaces. The origin of this photoresist dates back to 1964 (AZ® 111 S). It was one of the first commercial positive photoresist used for general purpose applications with contact printing. Meanwhile AZ® 111 XFS, a safer solvent version of AZ® 111 S, has advanced to meet today’s demands of semiconductor manufacturing and is still widely used where outstanding wet-etching capabilities (adhesion) and low sticking to the mask (proximity printing) are needed.
The suitable developer is the AZ® 303 Developer. You can use it in a dilution ratio of 1:3 to 1:4.
