Abstract

With the advancement in silicon interposer technology and Through Silicon Vias (TSVs) [1], [2], heterogeneous 2.5D integration at mm-wave frequencies is becoming more approachable than ever. In this work, we investigated co-planer GroundSignal-Ground (GSG) wirebonds as cost-effective interconnect for RF 2.5D applications. On-silicon GSG wirebonds of 25p.m diameter and 100 p.m pitch were realized and measured at different lengths and at frequencies up to 40 GHz. Circuit modeling of the measurements showed excellent agrement. dditionally, GSG wirebonds with lengths below 500p.m achieved insertion loss below 2 dB up to 40 GHz, while still leaving room for improvements, e.g., by reducing bond pitch or deploying ribbon bonds.
