Patent ID: 11177189

Abstract:
A module includes a substrate, a first component on a first main surface of the substrate and from which heat is to be dissipated, a sealing resin layer that encloses the first component, and a heat-dissipating member that includes a first and a second heat-dissipating portions. The first heat-dissipating portion is disposed in the sealing resin layer, spaced apart from an upper surfaces of the first component, and includes a first overlap portion that overlaps an upper surfaces of the first component when viewed in plan in a direction perpendicular to the first main surface. The second heat-dissipating portion extends from an undersurface of the first overlap portion to the upper surface of the first component. An area of the second heat-dissipating portion on a surface of the first overlap portion including the undersurface is smaller than an area of the first overlap portion.
