PPA layer depositionΒΆ

The standard patterning layer for the NanoFrazor is PPA. PPA is spin coated on the substrate. The thickness of the layer depends on the particular application. High resolution patterning normally requires only thin layer (15 nm thickness or less), while 3D patterning normally uses thicker layer (more than 30 nm thickness).
