What is photolithography?

Our technologies employ photoengraving processes to expose the surfaces of substrates coated with photoresist (a light-sensitive resin), creating a pattern.

Photo Etching division

Photo Etching division

By combining photolithography technology with wet etching, which uses the chemical corrosive effects of metals, we conduct precision work on various metallic ingredients.


Photomask division
