Abstract: A method of manufacturing an epitaxiable heat-dissipating substrate comprises the steps of (A) forming a roughened surface on a substrate made of a polycrystalline or amorphous material with a high thermal conductivity coefficient; (B) forming a flat layer on the roughened surface; and (C) forming a buffer layer on the flat layer. The flat layer reduces the surface roughness of the substrate, and then the buffer layer functions as a base for epitaxial growth, thereby being directly applicable to production of semiconductor devices which are flat and capable of isotropic epitaxial growth.

Abstract: The present invention provides a switching component of a directly flat-attached active frequency selective surface (AFSS) and fabricating method thereof. The present invention utilizes P-type and N-type thin film materials to fabricate a PN diode switching component capable of adjusting a resonance frequency of the AFSS, such that the AFSS together with the switching component could be integrally fabricated into a single thin film. Therefore, by utilizing a stepwise coating method to fabricate each layer with corresponding material, an equivalent length of a metal pattern could be adjusted, thereby changing the resonance frequency of the AFSS.

Abstract: A method of producing a secondary lens with hollow nano structures comprises the following steps (a) forming a polycrystalline seed layer on the surface of a lens; (b) growing a plurality of nano-rod structures over the polycrystalline seed layer in a random arrangement; (c) removing the portion of the seed layer where the nano-rod structure does not grow so that the surface of the lens therebeneath is exposed to outside; (d) sputtering a ceramic material layer over the plurality of nano-rod structures and the exposed surface portion of the lens; (e) removing the plurality of nano-rod structures and leaving a ceramic material layer having a plurality of hollow nano-rod structures in a random arrangement. A layer with hollow nano structures is formed on the surface of a lens wherein the hollow nano structures have the effect of scattering light and can improve the uniform illuminance of a secondary lens.
