Abstract: The present invention relates to an apparatus and method for three-dimensionally laminating a ceramic denture in a color-and-transmittance variable manner. A base slurry and a light transmissive slurry are mixed at a ratio regulated by a main controller according to a slurry ratio parameter datum, and then a slurry mixture is laid on a substrate by a laying module to form a slurry layer; next, the slurry layer is photocured by a photocuring module according to a laminated graphic under control of the main controller; in such a manner, the slurry layers are laminated and cured one by one so that a denture green body is formed; finally, the denture green body is sintered at a high temperature to form a ceramic denture. The present invention allows each slurry layer to exhibit different color and transmittance, resulting in quite natural gradation of color and gradation of transmittance.

Abstract: A method includes forming an insulating layer over a conductive feature; etching the insulating layer to expose a first surface of the conductive feature; covering the first surface of the conductive feature with a sacrificial material, wherein the sidewalls of the insulating layer are free of the sacrificial material; covering the sidewalls of the insulating layer with a barrier material, wherein the first surface of the conductive feature is free of the barrier material, wherein the barrier material includes tantalum nitride (TaN) doped with a transition metal; removing the sacrificial material; and covering the barrier material and the first surface of the conductive feature with a conductive material.

Abstract: A magnetic device adapted for various engine oil filtering apparatuses is proposed in the present invention. It includes an elastic metal plate; multiple holding bases, each of which has at least a containing portion, the holding bases being disposed on the elastic metal plate; and multiple magnets disposed in the containing portions of the holding bases respectively. The magnetic device has a sectional design and has various flexible combinations. Hence, it is more applicable and reduces the costs of production.
