A semiconductor apparatus includes: a system substrate; a semiconductor package mounted on the system substrate and having a first length in a first horizontal direction; a conductive label flexible and arranged on the semiconductor package, the conductive label including: a first adhesive layer contacting the semiconductor package; a thermally-conductive layer attached to the semiconductor package by the first adhesive layer and having a second length in the first horizontal direction greater than the first length; and a second adhesive layer contacting a portion of a surface of the conductive layer, the portion not vertically overlapping the semiconductor package; a thermal interface material (TIM) arranged on the conductive layer to vertically overlap the semiconductor package; and a cover including: a first cover portion vertically overlapping the semiconductor package and contacting the TIM; and a second cover portion to which the thermally-conductive layer is attached by the second adhesive layer.
