A substrate for a semiconductor package having a reinforcing member that prevents or minimizes distortions is presented. The substrate for the semiconductor package includes a substrate body, an insulation layer, and a reinforcing member. The substrate body has a first region having a plurality of chip mount regions, a second region disposed along a periphery of the first region, a circuit pattern disposed in each chip mount region and a dummy pattern disposed along the second region. The insulation layer covers the first and second regions and has an opening exposing some portion of each circuit pattern. The reinforcing member is disposed in the second region and prevents deflection of the substrate body.

A package stack includes at least two packages stacked on each other. Each package has a substrate, a circuit pattern positioned on the substrate, a semiconductor chip attached to the substrate, and a number of through-vias formed on a lateral surface. A number of electrical connection members are attached to the through-vias so as to electrically connect the packages to each other. The through-vias are vertically positioned on the lateral or side surface of the packages. And a solder ball is attached to the lower surface of the substrate of the lowest package.
