摘要: A method for manufacturing an embedded wiring board is provided. An activating insulation layer is formed, in which the activating insulation layer includes a plurality of catalyst particles, and covers a first wiring layer. An intaglio pattern and at least one blind via partially exposing the first wiring layer are formed on the activating insulation layer, in which some of the catalyst particles are activated and exposed in the intaglio pattern and the blind via. The activating insulation layer is dipped in a first chemical plating solution, and a solid conductive pillar is formed in the blind via through electroless plating. The activating insulation layer is dipped in a second chemical plating solution after the solid conductive pillar is formed, and a second wiring layer is formed in the intaglio pattern through the electroless plating. Components of the first chemical plating solution and the second chemical plating solution are different.
