Abstract

The present examples relate to a power semiconductor device. The present examples also relate to a power semiconductor device that maintains a breakdown voltage and reduces a gate capacitance through improving the structure of an Injection Enhanced Gate Transistor (IEGT), and thereby reduces strength of an electric field compared to alternative technologies. Accordingly, the present examples provide a power semiconductor device with a small energy consumption and with an improved switching functionality.
