Abstract
A semiconductor device is characterized by mixedly mount a logic chip, an analog chip, a memory chip, etc. by stacking them while stabilizing power supply lines and ground lines of each chip. The semiconductor device has an intermediate substrate having a conductive portion and also having, on its one surface, an external connection terminal conducted to the conductive portion; and semiconductor chips each of which has connection portions, and which are mounted on both the surfaces of the intermediate substrate. At least two of the above semiconductor chips are electrically conducted to each other via the conductive portion of the intermediate substrate. At least one of a power supply line, a ground line, and a signal line of each of the semiconductor chips is connected to the conductive portion of the intermediate substrate via two or more, conducted to each other, of the connection portions.
