MULTI-LAYERED ALUMINUM OXIDE CAPACITOR

摘要

The present invention relates to a multi-layered aluminum oxide capacitor comprising an aluminum substrate; a plurality of aluminum oxide layer formed in at least a portion of on both sides or one side of the substrate with respect to the aluminum substrate; and a plurality of electrode layers formed on the aluminum oxide layers. According to the present invention, manufacturing process is more simplified since Al2O3 insulation layer is formed by anodizing the aluminum layer without forming an extra insulation layer after forming the aluminum layer, so that the manufacturing cost can be reduced, and also a multi-layered capacitor having a high capacitance and a high reliability can be provided by stacking capacitors comprising a plurality of aluminum oxide layers using a more simplified process according to the present invention.
