    Abstract: A semiconductor chip includes a chip body and a plurality of solder-including electrodes provided on an element-formation surface of the chip body. A packaging substrate includes a substrate body, and one or more conductive layers and a solder resist layer that are provided on a front surface of the substrate body. The solder resist layer is provided as a continuous layer on the front surface of the substrate body and the one or more conductive layers, and has one or more apertures on each of the one or more conductive layers. The plurality of solder-including electrodes include two or more first electrodes having a same function other than a function of power supply. The one or more conductive layers include a continuous first conductive layer. The two or more first electrodes are connected to the continuous first conductive layer. The one or more apertures are confronted with the respective two or more first electrodes.

    Abstract: A semiconductor chip includes a chip body and a plurality of solder-including electrodes provided on an element-formation surface of the chip body. A packaging substrate includes a substrate body, and a plurality of wirings and a solder resist layer that are provided on a front surface of the substrate body. The plurality of solder-including electrodes include a plurality of first electrodes and a plurality of second electrodes. The plurality of first electrodes supply a first electric potential, and the plurality of second electrodes supply a second electric potential different from the first electric potential. The plurality of first electrodes and the plurality of second electrodes are disposed alternately in both a row direction and a column direction, in a central part of the chip body. The plurality of wirings include a plurality of first wirings and a plurality of second wirings. The plurality of first wirings connect the plurality of first electrodes, and the plurality of second wirings connect the plurality of second electrodes.
