摘要:
A through silicon via structure includes a top pad and a vertical conductive post that is connected to the top pad. The top pad covers a wider area than the cross section of the vertical conductive post. An interconnect pad is formed at least partially below the top pad. An under layer is also formed at least partially below the top pad. At least one dummy structure connects the top pad and the under layer to fasten the top pad and the interconnect pad.

A semiconductor die package is provided. The semiconductor die package includes a plurality of dies arranged in a stacked configuration. Through-silicon vias are formed in the lower or intermediate dies to allow electrical connections to dies stacked above. The lower die is positioned face up and has redistribution lines electrically coupling underlying semiconductor components to the through-silicon vias. The dies stacked above the lower die may be oriented face up such that the contact pads are facing away from the lower die or flipped such that the contact pads are facing the lower die. The stacked dies may be electrically coupled to the redistribution lines via wire bonding or solder balls. Additionally, the lower die may have another set of redistribution lines on an opposing side from the stacked dies to reroute the vias to a different pin-out configuration.
