发明名称 Substrate for semiconductor package with improved bumping of chip bumps and contact pads and semiconductor package having the same
摘要 The present invention relates to a substrate for a semiconductor package and a semiconductor package having the same. A substrate for a semiconductor package includes a substrate body; a contact pad group including a plurality of contact pads parallely arranged at a determined interval on a surface of the substrate body; dummy contact pads arranged at both sides of the contact pad group, respectively; and solder resist patterns covering the substrate body and having openings exposing the dummy contact pads and the contact pad group. When bumping the semiconductor chip having the bumps to the solders arranged on the contact pads formed on the substrate, the bumping defect caused due to different volumes of each solder can be prevented.
