Abstract
A semiconductor apparatus includes: a semiconductor device including a first electrode; a substrate including a second electrode and a recess; and a heat-dissipating adhesive material to set the semiconductor device in the recess so as to arrange the first electrode close to the second electrode, wherein the first electrode is coupled to the second electrode and the heat-dissipating adhesive material covers a bottom surface and at least part of a side surface of the semiconductor device.
