Photoresist for Front-end Applications

Alfa Chemistry provides a variety of photoresists for front-end sub-micron lithography and nano-lithography processes to customers who need them. If you are interested in our products, please click here.

These photoresists are used in semiconductor equipment manufacturing and optoelectronics, for terminal devices such as smartphones and tablet computers, as well as applications in the Internet of Things and autonomous driving technologies.

Alfa Chemistry is a leading supplier of semiconductor solutions with extensive experience. We consider the health and safety of our customers because we provide sustainable materials produced in an environmentally friendly way.

What Is Photoresist?

The photoresist is the basic material related to photolithography, which is light-sensitive materials, composed of a polymer, a sensitizer, and a solvent.

The photoresist is a light-sensitive coating that is used on the substrate of the structure-sapphire or silicon wafer. These structures are created by irradiating photoresist and then react to light. The photoresist is located in the areas exposed to light and disappears in the areas not exposed to light during development.
