Semiconductor device and method for manufacturing semiconductor device

A semiconductor device, comprising:

• a cooling device including a coolant passage;
• an insulating substrate connected to the cooling device;
• a semiconductor element connected to the insulating substrate by a soldered connection;
• an external connection terminal including a first end, which is electrically connected to the semiconductor element, and an opposite second end;
• and
• a resin portion molded to the insulating substrate, the semiconductor element, the first end of the external connection terminal, and at least part of the cooling device, the resin portion directly contacting at least part of the cooling device, wherein
• the cooling device includes a first shell plate and a second shell plate, each including peripheral portion,
• the insulating substrate is connected to an outer surface of one of the first shell plate and the second shell plate by a brazed connection,
• the resin portion is molded to a portion of the brazed connection, the brazed connection being between the insulating substrate and the outer surface of the one of the first shell plate and the second shell plate,
• the peripheral portion of the first shell plate is connected to the peripheral portion of the second shell plate by a second brazed connection to integrate the first shell plate and the second shell plate, and
• the coolant passage is formed between the first shell plate and the second shell plate.
