Abstract
Semiconductor device packages having top and bottom interconnecting surfaces that can be connected to external electrical systems are described. These packages include internal contact leads that are bent such that they extend from a top surface to a bottom surface of the package and thereby form the corresponding interconnecting surfaces. In some embodiments, a solder ball is formed on either the top or bottom portion of the contact leads so that the solder balls form one of the contact surfaces of the package.
