Abstract

A semiconductor device includes a first die, a second die on the first die, and a third die on the second die, the second die being interposed between the first die and the third die. The first die includes a first substrate and a first interconnect structure on an active side of the first substrate. The second die includes a second substrate, a second interconnect structure on a backside of the second substrate, and a power distribution network (PDN) structure on the second interconnect structure such that the second interconnect structure is interposed between the PDN structure and the second substrate.
