3D integration using inductive coupling and coupled resonator (Invited)

This paper describes a wireless inter-chip link using inductive coupling, namely ThruChip Interface (TCI) and a low-skew 3D clock distribution network using coupled resonator. Applying a TCI and a coupled resonator make it possible to integrate chips three dimensionally by applying conventional CMOS technology without new additional processing. Although the additional cost of a TCI is much lower than that of a through-silicon via (TSV), speed, power, reliability, and testability are not compromised.
