A method of manufacturing a semiconductor package includes providing a semiconductor chip including a circuit pattern, a connection pad, a first test pad and a second test pad, each of the connection pad, the first test pad and the second test pad respectively electrically connected to the circuit pattern, evaluating electrical characteristics of the semiconductor chip by applying a first test voltage to the first test pad and a second test voltage to the second test pad, the second test voltage being higher than the first test voltage, and electrically disconnecting the second test pad from the circuit pattern.
