| Outline of Final Research Achievements |
To achieve a high efficiency and high reliability of SiC power module which is expected to be a next generation power module, it is important to achieve high functionality of the resin/metal interface. The aim of this study is to create high-performance heterogeneous interfaces. Mechanical properties which are elastic modulus, tensile strength, fracture strain, fatigue properties and viscoelastic properties of cured thin-film of resin have been investigated. The effects of additives such as SiO2 filler and coupling agent on the mechanical properties have been also investigated. In addition, adhesive strength of a resin/copper interface and its degradation behaviors under high temperature and high-humidity/temperature conditions have been investigated. The results indicate that the preservation of coupling effect at high temperatures is effective to inhibit the degradation of the adhesive strength.
