Abstract
The present invention is intended to provide a semiconductor module and a DIMM module that are capable of stably supplying power to a plurality of stacked memory chips, a manufacturing method of the semiconductor module and a manufacturing method of the DIMM module. The semiconductor modulehaving a plurality of memory chipsincludes: a memory substratehaving a power supply circuitexposed on an arrangement surface as one surface of the memory substrate; and at least one memory unitarranged over the arrangement surface of the memory substrate. The memory unitincludes: the plurality of memory chipsstacked together such that a stacking direction D is along the arrangement surface; a through electrodepassing through the plurality of memory chipsin the stacking direction D; and an electrode layerformed on one end surface in the stacking direction D and connected to the through electrodeand the power supply circuit
