Abstract
The present invention is intended to efficiently implement noise countermeasures for a semiconductor circuit board and for a semiconductor circuit. The present invention is constituted by a control substrate, and a semiconductor circuit connected to the control substrate. The semiconductor circuit includes a substrate, an integrated circuit group, and a noise countermeasure, and is separated from the control substrate. The integrated circuit group includes an integrated circuit as a noise source. The substrate has a stacked multilayer structure, and shifts the frequency of a noise generated by the integrated circuit group to the high frequency side. The noise countermeasure is connected between the integrated circuit group and the control substrate. The noise countermeasure is a filter for attenuating the high frequency of a noise.
