| titleOfInvention | Method and apparatus for detecting reliability of IGBT power device |
| abstract | The invention relates to the power device field, especially to a method and apparatus for detecting reliability of an IGBT power device. A microscopic infrared measurement method is used for obtaining microscopic infrared thermographys of different substrate materials and power devices and thus peak junction temperatures under different substrate temperatures and on different bias conditions are obtained; with a temperature-sensitive parameter measurement method, an average thermal resistance value of the power device is obtained; and on the basis of the peak junction temperatures, the average thermal resistance value, and the microscopic infrared thermographys, the material, the structure, and the process of the power device are evaluated effectively. Therefore, the reliability of the IGBT power device can be evaluated accurately. |
