Overview
Sono-Tek’s ultrasonic coating technology is used for applications in which material consumption, uniformity, repeatability, and control are required. Our ultrasonic technology is well known in the semiconductor industry for precision photoresist coatings. Sono-Tek’s SPT200 photoresist coating machine is the perfect tool for providing uniform photoresist coverage of deep well topographies such as MEMs and other challenging applications where spin coating is not adequate. Other applications include polyimide, EMI materials, flux dispensing for flip chip applications as well as thin film solar/display applications like TCO layers, nano suspensions (CNT, graphene, nano-wires, etc), OPV polymers, AR, and CIGS active layers.
