摘要： A semiconductor device includes a conductive substrate, a conductive first joint portion arranged on the substrate, a SiC diode chip arranged on the first joint portion, a conductive second joint portion arranged on the SiC diode chip, and a transistor chip arranged on the second joint portion. The SiC diode chip includes a cathode pad arranged on one end and an anode pad arranged on the other end in the thickness direction. The cathode pad is joined to the substrate by the first joint portion. The transistor chip includes a drain electrode arranged on one end in the thickness direction. The anode pad is joined with the drain electrode by the second joint portion. The anode pad is arranged in a region enclosed by an outer edge of the SiC diode chip as viewed in a thickness direction of the substrate. The anode pad has an area larger than that of the transistor chip as viewed in the thickness direction of the substrate.

摘要： A electrochemical cell device includes: a cell having a first main surface and a second main surface opposite to the first main surface; a first current collector having a third main surface facing the first main surface; and a second current collector having a fourth main surface facing the second main surface. The cell is warped to protrude from the second main surface toward the first main surface. The third main surface is provided with a recess at a position facing a central portion of the first main surface. The fourth main surface includes a protrusion at a position facing a central portion of the second main surface. Each of the first current collector and the second current collector is constituted of one or more metal porous body sheets each composed of a metal porous body having a framework with a three-dimensional network structure.
