Abstract (en)

[origin: DE102006013670A1] The component has a surface for wide band anti reflection coating consisting of needle-like structures with nanometer dimensions with a larger aspect ratio of 4 :1. The surface is developed by reactive ion etching process (RIE) of silicon surfaces under application of processing gas such as oxygen and sulfur hexafluoride. The surface of a side or the surfaces of both sides of the component is non-reflective, where the needle-like structures consist of silicon coated with silicon dioxide.
