Abstract:
1. A method of manufacturing a capacitor-embedded printed circuit board using a first conductive layer formed on one side of an insulation layer, the method comprising: forming a second conductive layer on one side of the first conductive layer; forming a second electrode by removing a portion of the second conductive layer; forming a first electrode by removing a portion of the first conductive layer in correspondence with the second electrode; forming a dielectric layer on one side of the second electrode; and forming a third electrode in correspondence with the second electrode, wherein the first electrode and the second electrode are made from materials that react to different etchants, the first electrode does not react with a second etchant that reacts with the second electrode, the second electrode does not react with a first etchant that reacts with the first electrode, the forming the second electrode comprises removing a portion of the second conductive layer by applying the second etchant to a portion of the second conductive layer, and the forming the first electrode comprises removing a portion of the first conductive layer by using the second electrode as an etching resist and applying the first etchant to a portion of the first conductive layer.
