Haverhill, MA – Ultrasonic Systems, Inc. announces the recent sale of a Prism coating system for the application of photoresist.
Ultrasonic Systems, Inc. (USI), the leading manufacturer of high-performance ultrasonic spray coating equipment for solar, fuel cell, medical, and semiconductor applications, announces the recent sale of a Prism coating system for the application of photoresist. The Southern California-based customer requirements are to deposit a 0.6µm film of a photoresist on a curved optical lens device. Conventional spin coating technology was proven to be an ineffective method of applying the photoresist due to the lens’ shape and unique surface topography.
The Prism system, featuring USI’s proprietary nozzle-less ultrasonic spray head technology, is a fully programmable X-Y-Z coating system, for the thin, uniform application of photoresists, as well as polyimides, photoimagable soldermasks, conductive inks, and other proprietary low viscosity coatings. Available in batch configuration or with an in-line conveyor, the Prism is ideal for a variety of applications, including semiconductor wafers, MEMS, and glass panels.
“Our Prism systems are field-proven to reliably provide precise spray coating for a growing number of applications”, said Stuart Erickson, President of Ultrasonic Systems. “We’re pleased to once again provide a precision coating solution for a customer with unique process requirements.”
