Assignee: MITSUBISHI ELECTRIC CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H  B | IPC H

Claim 0:
1. A semiconductor module comprising:
a first lead;
a second lead;
a semiconductor element; and
a sealing material configured to seal a part of the first lead, a part of the second lead, and the semiconductor element,
wherein the first lead includes a die stage,
wherein the semiconductor element is bonded onto an upper side surface of the die stage,
wherein the sealing material on a lower side of the die stage is thinner than the sealing material on an upper side of the semiconductor element,
wherein the sealing material on a lower side of the die stage is thinner than the sealing material on a lower side of the second lead,
wherein a bent portion configured to form a step with respect to vertical direction in the first lead is provided in a region sealed with the sealing material in the first lead,
wherein a side on which the die stage is present of the step is positioned below a side on which the die stage is not present of the step due to the step,
wherein a side on which the die stage is not present of the step of the first lead protrudes from one end side of the sealing material,
wherein the second lead protrudes from a side opposite to the one end side of the sealing material, and
wherein a groove is provided on an upper side surface, a lower side surface, or both of the upper side surface and the lower side surface of the bent portion of the first lead.
