A sinter joining method with micron-submicron me tal Cu particles is proposed for high TJ semicond uctor die-attach such as application in emerging wide-bandgap high-power devices. The results sh ow that high bond strength exceeding 30 MPa ca n be realized by bonding at 300 °C in N2 gas und er low pressure. The obtained high strength in the mild bond-process conditions promises the opport unity of thermo-stable die-attach technology requi red for power device packaging. Die-attach for act ual SiC device was also prepared followed by vari ous environmental aging tests
