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: The present invention relates to a method for improving adhesion between ceramic and a thick film circuit. The method is particularly directed to accelerate the formation of a ceramic-metal eutectic phase between the ceramic carrier and the metal circuit by solid-phase diffusion bonding under a positive atmosphere. A metallic conductive slurry or its oxide slurry is printed on the surface of the ceramic carrier to form a circuit pattern by a thick film screen printing. The ceramic carrier is placed in an oven with temperature controlled by a program under a positive-pressure atmosphere of an inert gas including nitrogen, hydrogen or their mixtures. An eutectic phase is formed between the ceramic carrier and the metal circuit under a high temperature eutectic condition to increase the adhesion between the ceramic carrier and the thick film circuit.

Abstract: A method utilizes easily obtained carbon as carbon source for sintering, followed by high energy ball milling process with planetary ball mill for high energy homogenous mixing of the carbon source, solvent and nano-level silicon dioxide powder, along with a high energy ball milling process repeatedly performed using different sized ball mill beads, so as to formulate a spray granulation slurry with the optimal viscosity, to complete the process of micronization of carbon source evenly encapsulated by silicon dioxide powders. The optimal ratio of C/SiO2 is 1-2.5 to produce a spherical silicon dioxide powder (40-50 μm) evenly encapsulated by the carbon source. The powder is then subjected to a high temperature (1450□) sintering process under nitrogen gas. Lastly, the sintered silicon nitride powder is subjected to homogenizing carbon removal process in a rotational high temperature furnace to complete the fabricating process.

Abstract: A yellow light photolithographic process and an electroplating process are performed multiple times to produce copper plated layers on the aluminum nitride (AlN) substrate. The copper plated layers are plated in sequence into a stack structure with each layer having reduced length. The parameters of the yellow light photolithographic process can be adjusted, such that each copper plated layer is formed horizontally for a predetermined length into a stack structure of step layers tapering off upward, while a predetermined angle is formed by the tangent line passing through edges of the respective step layers, and the surface of the AlN substrate. An adhesion layer, a copper seed layer, a first copper plated layer, a second copper plated layer, a third copper plated layer, and a nickel plated layer are formed in sequence on the AlN substrate, to form a metalized circuit of multi-layer stack.
