| 摘要 |
The present invention is applied to a multilayer semiconductor device including a plurality of layered semiconductor chips. At least one of the plurality of layered semiconductor chips comprises a pad that is not connected to any external circuit terminal of the multilayer semiconductor device. The multilayer semiconductor device further comprises a separating element that connects the pad to a test stub line when each semiconductor chip is tested and separates the pad from the test stub line during the normal operation.
