Photoresists for Front-End Applications

We offer positive & negative tone photoresists in the lithography process for semiconductor device manufacturing and optoelectronics with offerings ranging from submicron to thick film resist products.

Core Resists for photo-lithography processes

We offer BB\X-over, g-line/i-line photoresists for front-end submicron lithography processes, as well as KrF photoresists for nanometer lithography processes. If you are interested in photoresists for back-end applications and/or thick-film photoresists (g-line/i-line), please click here.

These photoresists are used in semiconductor device manufacturing and optoelectronics, for terminal devices such as smartphones and tablets as well as applications in IoT and autonomous driving technology. We are a leading solutions supplier with extensive experience and proven lower total cost of ownership. We do this with our customer’s health and safety in mind as we produce our sustainable materials in an environmental friendly manner. 

What is a photoresist?

A photoresist is a light-sensitive coating that is used to structure a substrate - a sapphire or silicon wafer. The structures are created by illuminating the photoresist that then reacts to light. The photoresist resides in areas that are exposed to light and vanishes during developing in areas not exposed to light.
