Patent ID: 6845012

Claim:
A cooled type semiconductor switching module comprising: a high-sided semiconductor chip having a high-sided semiconductor switching element; a low-sided semiconductor chip having a low-sided semiconductor switching element, and constituting an inverter circuit with said high-sided semiconductor chip; and a high-sided plate, a middle-sided plate, and a low-sided plate, which are made of metal plates, respectively, wherein: main electrode surfaces of both said semiconductor chips on output sides thereof are separated from each other, and are electrically connected to an inner surface of said middle-sided plate; another surface of said high-sided semiconductor chip is electrically connected to an inner surface of said high-sided plate; another surface of said low-sided semiconductor chip is electrically connected to an inner surface of said low-sided plate; and both said semiconductor chips are covered in an integral form by a sealing resin portion, while exposing outer surfaces of said middle-sided plate, said high-sided plate, and said low-sided plate.
