    • A fabrication method of a packaging substrate includes the steps of: forming a recess by etching a predetermined area of a lower surface of a substrate; depositing a seed layer on an upper surface of the substrate; in the recess, etching predetermined area(s) of the lower surface of the substrate and forming at least one via hole that reaches the seed layer; and plating the inside of the via hole by using the seed layer, and forming electrode(s) for electrically coupling the upper and lower parts of the substrate. First and second pads coupled to the electrode(s) may be formed on the upper and lower parts of the substrate, respectively. Thus, using the second pads as bonding materials, the packaging process becomes easier, which resultantly simplifies the fabrication process of the packaging substrate and the packaging process.
    • 包装基板的制造方法包括以下步骤:通过蚀刻基板的下表面的预定区域来形成凹部; 在基板的上表面上沉积种子层; 在所述凹部中蚀刻所述基板的下表面的预定区域并形成到达所述籽晶层的至少一个通孔; 并且通过使用晶种层对通孔的内部进行电镀,以及形成用于电耦合衬底的上部和下部的电极。 分别连接到电极的第一和第二焊盘分别形成在衬底的上部和下部。 因此,使用第二焊盘作为粘合材料,封装过程变得更容易,从而简化了封装衬底的制造过程和封装过程。
