This paper presents all lead free IGBT module structure with low thermal resistance and high reliability. Using thick copper foil alumina DCB, Sn/Ag/In solder, and copper base, we have achieved low thermal resistance as same as the current aluminum nitride (AlN) IGBT module structure. In addition to low thermal resistance, this new structure shows excellent temperature cycling capability of 3000 cycles
