Abstract
Disclosed herein is a method for testing a semiconductor device, the method includes: preparing a first semiconductor chip having a first bump electrode and a first driver circuit that drives the first bump electrode, and a second semiconductor chip having a second bump electrode and a second driver circuit that drives the second bump electrode; staking the first and second semiconductor chips so that the first bump electrode and the second bump electrode are electrically connected to each other to form a current path including the first and second bump electrodes; and driving, in a test mode, the current path to a first potential by the first driver circuit while driving the current path to a second potential different from the first potential by the second driver circuit.
