Characterization of Ultraviolet-Cured Methacrylate
网页The UV-curing resin is applied on a silicon wafer and a spin coater is used to obtain a homogeneous layer with a defined thickness. A spinning speed of 357 rpm for 30 s is used to obtain a layer thickness of approximately 100 μm. The resin is then UV-cured in an inert atmosphere to avoid oxygen inhibition as described in our previous study.
