| Outline of Final Research Achievements |
Which is one of the solutions to the corresponding global warming problem, reliability of an important technology of environment-friendly vehicles such as electric cars inverter, large capacity, insulated gate bi-Polar is an essential component thereof to downsizing the high performance and high reliability of the transistor (IGBT) module junction between the electrodes is important. The junction between the electrodes the aluminum wire is used, performance and reliability of the wire is critical. In this study, we developed a new aluminum copper alloy wire for high-temperature next-generation power semiconductor packaging, was to clarify the relationship of the copper added amount and the aging treatment conditions of the relationship and the wire tissue of the precipitation phase of the aluminum.
