Description

PHOTO-R plates are glass plates coated with positive tone photoresist. We are not using spin coating, so those plates have uniform photoresist layer thickness over whole plate surface.

Our photoresist is very similar to Shipley photoresist S1800 series and produces even better resultant structures – see examples here.

PHOTO-R  photoresist is a positive polymeric substance – i.e. it becomes soluble in a certain alkaline solution after exposure to short wavelength light.

After exposure material should be processed for 30seconds in AZ303 developer diluted in deionized water at 1:9.

Exposure can be calculated using our Online Exposure Calculator.
