MIMOS Ultrasonic Coater for Nanomaterial Deposition (Mi-Atomizer)

Overview

High quality ultrathin films are being produced in bulk for demanding coating applications such as smart screens, drug eluting stents, fuel cells and electronic devices. One effective method for producing quality ultra-thin coating is by way of ultrasonic nozzle spray coating. MIMOS working with a local micro-dispenser equipment manufacturer have realized an industry grade automated ultrasonic spray coater with high throughput targeted for electronic applications.

Mi-Atomizer is a commercial ultrasonic coater, a result of
MIMOS collaboration with a local microdispensing equipment
manufacturer. It is used for ultrathin coating applications down to a few nanometers thick. The robotic handling of the ultrasonic nozzle enables fast coating process of nanomaterials onto large substrates. Currently made for 2D coating applications using proprietary nanomaterials, the equipment is able to coat highly uniform layer almost 2nm thick over an 8-inch silicon wafer. Due to possible toxic nature of nanomaterials, the equipment is built with efficient exhaust and safety features.
