Photolithography

Mask alignment during thin film fabrication

Photolithography is the process of using light to transfer images from a photomask to a coated thin film substrate. The key to the process is the use of a light-sensitive chemical called photoresist and a precision phototool, called a photomask. The photomask is custom tooling made from customer CAD files.
