The future of electronics hinges on miniaturization—and at the heart of that process is Photoresist. As manufacturers strive to develop smaller, faster, and more efficient chips, photoresist materials play a pivotal role in enabling extreme precision.

In chip fabrication, photoresists allow engineers to etch intricate circuit patterns onto silicon wafers. These patterns must be accurate to the nanometer, and that’s where photoresist’s sensitivity to light becomes critical. As UV and EUV lithography advance, so does the demand for highly engineered photoresist formulations that can withstand radiation, maintain resolution, and support high throughput.

Today’s fabs rely on multiple types of photoresist—positive, negative, chemically amplified resists (CARs), and more—each tuned for specific applications and resolutions. The surge in demand for AI processors, 5G chips, and automotive electronics is pushing suppliers to innovate quickly.

Global players in the photoresist market are investing heavily in R&D to meet the growing needs of cutting-edge semiconductor design. This includes expanding capabilities for deep UV and extreme UV resists that can keep pace with Moore’s Law.

As chipmakers push the boundaries of possibility, photoresist remains one of the most critical and innovative materials in the entire supply chain.
