Semiconductor device and method for producing the same

摘要

A semiconductor device includes the first through third semiconductor devices which are stacked on a substrate and the first through third wires for connecting the semiconductor elements and the substrate. The first wires serve to connect electrodes of the first semiconductor element positioned uppermost and electrodes of the second semiconductor element. The second wires serve to connect the electrodes of the second semiconductor element and electrodes of the third semiconductor element. The third wires serve to connect the electrodes of the third semiconductor element and bonding pads of the substrate. Between the first wires and the electrodes of the second semiconductor element and between the second wires and the electrodes of the third semiconductor element, stud bumps are provided so as to form space therebetween, thereby avoiding short-circuits therebetween.
