半导体装置
By setting a plate-shaped opposing section between the power supply terminal and the output terminal, the current direction is reversed, thus canceling out the self-inductance. This solves the surge voltage and EMI noise problems of SiC power devices, realizes the design of low self-inductance power modules, and improves the reliability and efficiency of the devices.

AI Technical Summary
High-speed switching of SiC power devices in existing technologies leads to increased surge voltage, posing risks of device damage and increased EMI noise. Furthermore, the existing wiring has high self-inductance, making it difficult to further improve the efficiency of power modules.
By employing power terminals and output terminals arranged adjacent to each other in a planar view, and by providing plate-shaped opposing portions in the connection portion and wiring connection portion of the power terminals, the current flows in opposite directions during the transition period, thereby canceling out self-inductance and reducing the self-inductance of the internal wiring.
It effectively reduces the self-inductance of the internal wiring of the power module, reduces surge voltage, improves the reliability of the device, reduces EMI noise, and improves the efficiency of the power module.
