Hi,

I use a photosensitive Polyimide to pattern my structures.
PI2721 behaves like -ve photoresist.
During development it is important that no water is in
contact with the Polyimide.

After development and spin drying to remove any liquid in
contact with the Polyimide surface, the Polyimide is cured.

Hope this helps

Best wishes
Anupama
