Patent ID: 11948850
Assignee: MITSUBISHI ELECTRIC CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H  B | IPC H

Claim 29:
30. A method for manufacturing a semiconductor module,
the semiconductor module including:
a lead including a die stage,
a semiconductor element bonded onto an upper side surface of the die stage, and
a sealing material configured to seal at least a part of the lead and the semiconductor element,
in the semiconductor module, the sealing material on a lower side of the die stage being thinner than the sealing material on an upper side of the semiconductor element,
the method comprising sealing the die stage and the semiconductor element,
wherein the sealing includes injecting the sealing material into a cavity of a mold,
wherein the sealing includes supporting the lead by the mold so that the die stage is positioned inside the cavity, and
wherein the sealing includes, after at least partially injecting the sealing material into the cavity, deforming a portion positioned inside the cavity in the lead to move the die stage downward, and then curing the sealing material.
