SEMICONDUCTOR DEVICE AND INVERTER COMPRISING SEMICONDUCTOR DEVICE

To provide a semiconductor device that achieves both of a low inductance and an equivalent inductance and an inverter having the semiconductor device.SOLUTION: In a semiconductor device and an inverter having the semiconductor device, an upper arm semiconductor element on a positive electrode wiring board and an AC wiring board are connected by a first wiring member, and a lower arm semiconductor element on the AC wiring board and a negative electrode wiring board are connected by a second wiring member. The AC wiring board includes: a first region where the first wiring member is connected; a second region where the lower arm semiconductor element is provided; and a connection region that connects the two regions. The connection region is positioned at a position opposite to positive electrode and negative electrode terminals with the region where the first and second wiring members are used intervening therebetween, and the positive electrode wiring board, the negative electrode wiring board, the first region, and the second region are arranged in this order.SELECTED DRAWING: Figure 3 【課題】低インダクタンスと等インダクタンスとを両立した半導体装置および半導体装置を備えたインバータを提供する。【解決手段】半導体装置および半導体装置を備えたインバータは、正極配線板上の上アーム半導体素子と交流配線板とが第１配線部材で接続され、交流配線板上の下アーム半導体素子と負極配線板とが第２配線部材で接続され、前記交流配線板は、前記第１配線部材が接続される第１領域と、前記下アーム半導体素子が設けられる第２領域と、その２つの領域を接続する接続領域と、を有し、前記接続領域は、前記第１・第２配線部材が用いられる領域を間にして、前記正極・負極端子とは反対の位置であり、前記正極配線板、前記負極配線板、前記第１領域、前記第２領域の配置順である。【選択図】図３
