    摘要： A manufacturing method is disclosed which ensures strength of a wafer and improves device performance. A thermal diffusion layer is formed from a front surface of a wafer. A tapered groove which reaches the thermal diffusion layer is formed from a back surface by anisotropic etching with alkaline solution. In-groove thermal diffusion layer is formed on side wall surfaces of the groove. A separation layer of a reverse blocking IGBT is configured of the thermal diffusion layer and the in-groove diffusion layer. The thermal diffusion layer is formed shallowly by forming the in-groove diffusion layer. It is possible to considerably reduce thermal diffusion time. By carrying out an ion implantation forming the in-groove diffusion layer and an ion implantation forming a collector layer separately, it is possible to select an optimum value for tradeoff between turn-on voltage and switching loss, while ensuring reverse blocking voltage of the reverse blocking IGBT.

The buffer circuit has no protection diode connected with an input terminal thereof on a power-source side, and connected to a common power source shared with the micro controller unit. The switch is one for controlling the power source of the micro controller unit and buffer circuit. The micro controller unit is made to transition to an active state to either a standby state or a power-source cutoff state during the standby time.
