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

Claim 8:
9. A manufacturing method of a semiconductor device comprising:
bonding a semiconductor chip, which includes a main electrode and a control electrode, to a substrate;
bonding a main electrode member to the main electrode via a first bonding material;
bonding a control electrode member to the control electrode via a second bonding material;
putting the semiconductor chip, the substrate, the main electrode member, and the control electrode member, which are bonded, into a mold; and
sealing the semiconductor chip, the substrate, the main electrode member, and the control electrode member with sealing material by injecting the sealing material into the mold in a state that distal end surfaces of the main electrode member and the control electrode member are pressed against a buffer material provided between the main electrode member and the mold and between the control electrode member and the mold,
wherein the sealing material is not ground.
