Patent ID: 11961780
Assignee: HITACHI ASTEMO, LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor module, comprising:
a semiconductor device that includes
a semiconductor element,
a pair of conductors that is arranged so as to sandwich the semiconductor element and face each other in a thickness direction, and connected to the semiconductor element, respectively,
a first heat dissipation member that is arranged on a surface of a side opposite to the semiconductor element of one conductor of the pair of conductors via an insulating member, and includes a first connecting portion extending outward from an outer peripheral side surface of the one conductor,
a second heat dissipation member that is arranged on a surface of a side opposite to the semiconductor element of the other conductor of the pair of conductors via an insulating member, and includes a second connecting portion extending outward from an outer peripheral side surface of the other conductor, and
a resin for sealing the outer peripheral side surfaces of the pair of conductors; and
a flow path forming body that is connected to the first connecting portion of the first heat dissipation member and the second connecting portion of the second heat dissipation member of the semiconductor device,
wherein a first elastically deformed portion which is elastically deformed is provided such that a distance in a thickness direction between an outer peripheral end of the first connecting portion of the first heat dissipation member and an outer peripheral end of the second connecting portion of the second heat dissipation member becomes smaller than a distance in a thickness direction between an intermediate portion of the first connecting portion of the first heat dissipation member and an intermediate portion of the second connecting portion of the second heat dissipation member, and
wherein the resin is filled between the first connecting portion of the first heat dissipation member and the second connecting portion of the second heat dissipation member.
