Assignee: HYUNDAI MOBIS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A manufacturing method of a cooling power module to cool dual sides of a semiconductor chip, the method comprising:
forming a recessed portion on one surface of a lower substrate;
disposing the semiconductor chip in the recessed portion;
forming lead frames at both ends of the lower substrate;
applying a first conductive adhesive to an upper surface of the semiconductor chip;
applying a first nonconductive adhesive to the one surface of the lower substrate and a portion of the lead frames; and
bonding an upper substrate to the semiconductor chip through the first conductive adhesive, and to the portion of the lead frames and the lower substrate through the first nonconductive adhesive;
wherein the upper substrate and the lower substrate are provided in a form of multi-chips, and cooling is performed to cool dual sides of the semiconductor chip.
