Abstract
A semiconductor package includes a set of stud bumps, which can be formed by wire bonding technology and can be bonded or joined to a semiconductor element to form a stacked package assembly. Since the process of bonding the semiconductor element to the stud bumps can be carried out without reflow, an undesirable deformation resulting from high temperatures can be controlled or reduced.
