ND-SP Ultrasonic Spray Coater


The Ultrasonic Spray Coater ND-SP is a system developed for the fabrication and deposition of thin films via spray. ND-SP has been designed with the objective to perform Spray Coating techniques, such as Sol-Gel, which require uniform and very small drop sizes. Thanks to its ultrasonic spray nozzle, the system is capable to produce drops with an average diameter of 20 micrometers and a very uniform tight drop distribution. Moreover, ultrasonic nozzle allows superior spray and coating results as well as a reduction of the coating material, up to 80%. 


The dissolution is supplied through a syringe pump which offers high precision, versatility, inter-change and an easily used system. In this sense, it is possible to carry out depositions with a wide range of flows. 




The software, which is based on Windows®, is of easy management and allows programming any type of spray sequence depending on the size of the samples as well as the number of deposition samples. With the aim to speed up the drying of the deposition, the ND-SP Ultrasonic Spray Coater could include an additional system for drying using air blast where temperature could be adjusted.

Solar Cells

The Ultrasonic Spray Coating technology allows reducing the manufacturing costs of Solar Cell. The system offers the possibility of controlling the over-spray and the quality of the coating.


Ultrasonic spray coating technology is used to spray uniform photoresist coatings onto high aspect ratio MEMs devices. The system allows achieving uniform coverage along the top, side walls and bottoms of deep grooves as opposed to spin coating techniques.
