| Zusammenfassung: | A power semiconductor module includes an insulating substrate, a first conductive circuit pattern, a second conductive circuit pattern, a first semiconductor device, a second semiconductor device, a sealing member, and a first barrier layer. The sealing member seals the first semiconductor device, the second semiconductor device, the first conductive circuit pattern, and the second conductive circuit pattern. At least one of the first barrier layer and the sealing member includes a first stress relaxation portion. This configuration improves the reliability of the power semiconductor module. |
