Optical coating in the nanometer-scale requires a high level of accuracy regarding layer properties such as thickness, composition, conformality and stress control.
In order to ensure an excellent uniformity and conformality in layer-thickness, atomic layer deposition (ALD) is used for depositing optical thin films applied as e.g. anti-reflective coatings or optical filter systems. SENTECH uses the advantages of the Planar Triple Spiral Antenna (PTSA) ICP source in ICPEALD processing.
