Abstract:
A system for surface patterning using a three dimensional holographic mask includes a light source configured to emit a light beam toward the holographic mask. The holographic mask can be formed as a topographical pattern on a transparent mask substrate. A semiconductor substrate can be positioned on an opposite site of the holographic mask as the light source and can be spaced apart from the holographic mask. The system can also include a base for supporting the semiconductor substrate.
