Hybrid bonding materials comprising ball grid arrays and metal inverse opal bonding layers, and power electronics assemblies incorporating the same
10403594 · 2019-09-03 · ·

A hybrid bonding layer includes a metal inverse opal (MIO) layer with a plurality of hollow spheres and a predefined porosity, and a ball grid array (BGA) disposed within the MIO layer. The MIO layer and the BGA may be disposed between a pair of bonding layers. The MIO layer and the BGA each have a melting point above a TLP sintering temperature and the pair of bonding layers each have a melting point below the TLP sintering temperature such that the hybrid bonding layer can be transient liquid phase bonded between a substrate and a semiconductor device. The pair of bonding layers may include a first pair of bonding layers with a melting point above the TLP sintering temperature and a second pair of bonding layers with a melting point below the TLP sintering temperature.
