Abstract

Transient Liquid Phase (TLP) bonding is a promising technique for SiC and other wide-bandgap power semiconductor device die-attach and high temperature packaging. TLP bonding advances modern solder technology by raising the solder melting point to over 500 °C with a low 200 °C processing temperature that creates much greater mechanical reliability and rigidity while the thermal conductivity of the die-attach is increased by 67% and the thermal resistance reduced by an order of magnitude over the traditional Sn-Pb solders. It is also shown here that Au-In TLP bonds exude excellent electrical reliability with thermal cycling degradation if designed correctly as experimentally confirmed.
