    • A manufacturing method of an embedded wiring board is provided. The method includes the following steps. First, an insulation layer and a lower wiring layer are provided, wherein the insulation layer includes a polymeric material. Then, the plural catalyst grains are distributed in the polymeric material. A groove and an engraved pattern are formed on the upper surface. A blind via is formed on a bottom surface of the groove to expose the lower pad. An upper wiring layer is formed in the engraved pattern. Some catalyst grains are exposed and activated in the groove, the engraved pattern and the blind via. A first conductive pillar is formed in the groove. Finally, a second conductive pillar is formed in the blind via.
    • 提供了一种嵌入式布线板的制造方法。 该方法包括以下步骤。 首先,提供绝缘层和下布线层,其中绝缘层包括聚合材料。 然后,多个催化剂颗粒分布在聚合物材料中。 在上表面上形成有凹槽和雕刻图案。 在槽的底表面上形成盲孔以露出下垫。 上部布线层形成在雕刻图案中。 一些催化剂颗粒在凹槽,雕刻图案和盲孔中暴露和活化。 第一导电柱形成在凹槽中。 最后,在盲通孔中形成第二导电柱。
