Sono-Tek

Sono-Tek is a global leader in ultrasonic coating technology, delivering precision solutions for advanced manufacturing where material efficiency, uniformity, repeatability, & process control are essential. Our ultrasonic systems are widely used in the semiconductor industry, especially for high-precision photoresist applications. Our SPT200 Photoresist Coating System provides highly uniform coverage over deep-well topographies such as MEMS and other complex geometries where traditional spin coating falls short. For increased automation and throughput, we offer a Wafer Handling System for 4–8" wafers with automated loading to support high-volume production. Beyond photoresist, our ultrasonic spray technology supports semiconductor and electronics applications including polyimide and EMI coatings, flux deposition for flip-chip, and functional coatings for thin film solar, displays, and advanced packaging, including TCO, CNT, graphene, nanowire, OPV, AR, and perovskite mater
