The interconnect substrate is configured to be mounted on the at least one die and to have the at least one discrete component mounted on the interconnect substrate. Each of the cathode electrodes includes a line electrode having a groove at one lateral side surface thereof, and isolation electrodes formed on the substrate exposed through the groove such that the isolation electrodes are isolated from the line electrode.
