Abstract
A semiconductor device includes a circuit board including a ground portion, and a semiconductor package disposed on the circuit board. The semiconductor package includes an external connecting pad and an exposed pad. The exposed pad and the ground portion are electrically connected at a first surface of the exposed pad. A semiconductor chip is disposed on a second surface of the exposed pad and electrically connected to the external connecting pad. The first surface of the exposed pad is located external to the semiconductor package, and the second surface of the exposed pad is located within the semiconductor package. A test pad is disposed on the semiconductor chip and is electrically connected to the exposed pad.
