An SiP (semiconductor device) using a stacked packaging method for stacking a microcomputer IC chip over a driver IC chip in which circuits sensitive to heat or noise, including an analog to digital conversion circuit, a digital to analog conversion circuit, a sense amplifier circuit of a memory (RAM or ROM), or a power supply circuit of a microcomputer IC chip, are prevented from two-dimensionally overlapping with a driver circuit of the lower-side driver IC chip to reduce, during the operation, the effect of heat or noise, which the circuits sensitive to heat or noise of the microcomputer IC chip receive from the driver circuit of the lower-side driver IC chip, thereby improving the operation stability of the SiP (semiconductor device) using the stacked packaging method.
