2 |4 v7 _0 d. _. H! X1 GVolume production of 3D ICs with through-silicon vias (TSVs) is expected within a few years. Early adopters of this new technology can expect higher bandwidths, lower power, increased density and reduced costs. But without “3D aware” tools and a mature supply chain ecosystem, 3D ICs cannot move into mainstream IC design flows.* l3 ~9 N0 J3 ~, I# D7 h. A# d
5 P( ?' w, \5 M. }. Z: r0 V+ @! F# G3D ICs are attractive because they enable an assortment of die, manufactured at various process nodes, to be stacked. For example, a 28 nanometer high-speed digital logic die could be stacked with a 130 nanometer analog die. Thanks to such capabilities, heterogeneous 3D ICs with TSVs are expected to have a broad impact in such areas as networking, graphics, mobile communications, consumer devices and computing.
