Abstract: A power module includes a first metal layer-coated substrate, a plurality of chips, and a first connection piece. A first electrode of each chip is electrically connected to a first metal layer of the first metal layer-coated substrate. The first connection piece includes a first main body part and a plurality of first contact parts. A second electrode of each of the plurality of chips is in contact with at least one of the first contact parts. A part of the first main body part is between at least one pair of adjacent first contact parts. A current flowing out from the chip directly flows to the first main body part through the first contact part. The chips are connected in parallel by using the first connection piece.

Abstract: A power module includes a first metal layer-clad substrate and a second metal layer-clad substrate that are disposed opposite to each other, and a chip and an interconnection pillar that are located between the first metal layer-clad substrate and the second metal layer-clad substrate. The chip and the first metal layer-clad substrate are electrically connected through press sintering by using a sintering material to improve bonding reliability. The chip is electrically connected to the second metal layer-clad substrate by using the interconnection pillar.
