Economic high-throughput processes by means of spatial atomic layer deposition

Very high layer-thickness uniformity and precise thickness control are imperative for optical applications, as deviations from target values affect optical performance. Atomic layer deposition can be used to achieve high uniformity and reproducibility of layer deposition even on complex-geometric substrates.  

Whereas conventional ALD systems require time-consuming rinsing routines, spatial atomic layer deposition enables a high coating rate whilst maintaining the coating-technology advantages. As a result of the integration possibility of further coating and activation technologies in a hybrid area, the advantages of other technologies (e.g. PVD, CVD) can be implemented in this system in order to develop innovative coating and material systems for groundbreaking solutions.
