Abstract
A technique of assembling a plurality of chips is disclosed. A plurality of chip layers, each of which includes at least one chip block, is prepared. Each chip block includes a plurality of electrodes assigned the same function. The plurality of the chip layers is sequentially stacked with rotation so as to configure at least one stack of overlapping chip blocks. Each stack holds a plurality of groups of vertically arranged electrodes with shifts in horizontal plane. A through hole is formed, for at least one of the groups, into the plurality of the chip layers at least in part so as to expose electrode surfaces of vertically arranged electrodes in the group. The through hole is filled with conductive material.
