The POLOS® UC330 is a compact, tabletop ultrasonic spray coating system developed for high-accuracy coating tasks in R&D environments and low-volume production. It is ideally suited for applications such as photoresist deposition on a wide range of wafer materials, as well as the formation of functional and thin-film layers where uniformity and material control are critical.
High efficiency, minimal material waste
By leveraging advanced ultrasonic spray technology, the UC330 achieves highly controlled nanoparticle deposition while significantly reducing chemical consumption. Material utilization rates above 95% help lower photoresist usage, reduce operating costs, and improve overall process efficiency compared to conventional coating techniques.
Designed around user flexibility
The UC330 combines a small footprint with intuitive software control, making it easy to operate and integrate into existing workflows. A broad selection of ultrasonic nozzles and optional accessories allows the system to be configured precisely to match specific application requirements, ensuring optimal coating performance across different processes.
Integrated, ready-to-use platform
Supplied as a complete system, the POLOS® UC330 includes an integrated syringe pump, carrier gas control, ultrasonic generator, and a programmable motion system. Its patented ultrasonic spray technology delivers a fine, stable spray pattern for highly uniform coatings, even on complex or structured surfaces.
