SEMICONDUCTOR DEVICE AND A MANUFACTURING METHOD OF THE SEMICONDUCTOR DEVICE
A semiconductor device including a semiconductor module 10A, a semiconductor module 10B that has a lower switching voltage threshold than the semiconductor module 10A, and busbars 331 and 32 that connect the semiconductor module 10A and the semiconductor module 10B in parallel to a common terminal. The semiconductor module 10B is connected at a connection point on the busbar 32 at which the inductance relative to the common terminal is higher than that of the semiconductor module 10A. The semiconductor module 10B with the low threshold voltage is turned ON faster than the semiconductor module 10A with the high threshold voltage for input of a common switching voltage, but can restrict the rising of the current due to the high inductance of the busbar 32, thereby enabling restriction of the current imbalance.
Packaging mechanisms for dies with different sizes of connectors
Embodiments of mechanisms for testing a die package with multiple packaged dies on a package substrate use an interconnect substrate to provide electrical connections between dies and the package substrate and to provide probing structures (or pads). Testing structures, including daisy-chain structures, with metal lines to connect bonding structures connected to signals, power source, and/or grounding structures are connected to probing structures on the interconnect substrate. The testing structures enable determining the quality of bonding and/or functionalities of packaged dies bonded. After electrical testing is completed, the metal lines connecting the probing structures and the bonding structures are severed to allow proper function of devices in the die package. The mechanisms for forming test structures with probing pads on interconnect substrate and severing connecting metal lines after testing could reduce manufacturing cost.
