Assignee: HITACHI ASTEMO, LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A power semiconductor device, comprising:
a first insulating substrate on which a first conductor layer is arranged on one surface;
a semiconductor element; and
a first conductor, comprising a peripheral portion and a narrow portion, the peripheral portion connected to the first conductor layer via a first connecting material, the narrow portion connected to the semiconductor element via a second connecting material;
wherein, when viewed from a direction perpendicular to an electrode surface of the semiconductor element,
the narrow portion of the first conductor is narrower than the peripheral portion of the first conductor,
the peripheral portion of the first conductor is larger than the semiconductor element, and
a first recess is formed in the peripheral portion so that a thickness of the first connecting material becomes thicker than other portions.
