Abstract

A semiconductor device including a semiconductor chip having a first surface and a second surface opposite to the first surface, a first heat dissipation member on the second surface of the semiconductor chip, the first heat dissipation member having a vertical thermal conductivity in a direction perpendicular to the second surface, and a horizontal thermal conductivity in a direction parallel to the second surface, the first vertical thermal conductivity being smaller than the first horizontal thermal conductivity, and a second heat dissipation member comprising a vertical pattern penetrating the first heat dissipation member, the second heat dissipation member having a vertical thermal conductivity that is greater than the vertical thermal conductivity of the first heat dissipation member may be provided.
