Power Module and Substrate Structure Applied to Power Modules

摘要

A substrate structure applied to a power module according to an embodiment of the present invention is provided. A substrate applied to the power module includes an upper substrate and a lower substrate, and the lower substrate includes device regions on which a plurality of semiconductor devices are disposed, a source signal electrode unit for transmitting a source signal to the semiconductor devices, and the semiconductor devices. a gate signal electrode part for transmitting a raw gate signal, wherein either the source signal electrode part or the gate signal electrode part is connected to the upper substrate through a conductive pillar, and the source signal electrode part or the gate signal electrode part A signal transmitted by any one is transmitted to the semiconductor devices through the upper substrate.
