1 | Market Overview
Photoacid generators (PAGs) are light-sensitive compounds that release protons (acid) when exposed to UV or EUV radiation, playing a crucial role in photolithography, photoresist systems, and nano-patterning. Widely utilized in semiconductor fabrication, microelectronics, MEMS, and printed electronics, PAGs facilitate high-resolution pattern transfer in photoresist films.
The market for PAGs is expanding due to the evolution of extreme ultraviolet (EUV) lithography, increased adoption of advanced packaging techniques, and the growth of flexible displays and photopolymer-based manufacturing. Additionally, research applications in 3D microfabrication, photoinduced polymerization, and smart coatings are driving demand for next-generation PAGs.
