PROCESS DESCRIPTION

DSI has been producing complex functional thin film coatings on a variety of flexible substrates for over twenty years. Materials include metals, dielectrics, and multilayer optical coatings. DSI’s core enabling technology is an internally-developed batch coating process known as MicroDyn®. MicroDyn utilizes a proprietary magnetron sputtering chamber custom designed for high throughput processing. The unique MicroDyn batch process is not restricted by the line speed limitations and multi-pass transits associated with roll-to-roll systems—it can deposit hundreds of layers just as easily as a single layer. The MicroDyn process balances coating stress on both sides of the substrate, which aids in handling and increases coating durability. Through third parties, DSI also offers complex surface patterning using laser ablation.
