Our POLOS® PC320 table-top photoresist spray coating system utilizes a unique ultrasonic spray coating technology to evenly coat the photoresist on the surfaces of substrates such as MEMs, wafers, masks and other substrates with various topographies.
The POLOS® PC320 system allows highly precision nano-particle coating with more efficient photoresist consumption compared to standard photoresist application techniques. On our Ultrasonic Spray Coating Systems the material usage ratio exceeds 95%, this will allow our users to reduce costs of photoresist consumption and improve their process efficiency. Listening to the needs of our customers, we designed a compact system with easy-to-use software controls, the ability to choose from the wide range of Ultrasonic Nozzles and complimentary options will allow you to find the perfect match for their process application.
The POLOS® PC320 is standard supplied with integrated syringe pump, carrier gas regulation, ultrasonic generator and controllable motion system. With patented ultrasonic spray technology, the system can provide highly uniform and efficient fine spray coating.
