Abstract

According to one embodiment of the present invention, a mounting substrate is installed on a multi charged particle beam irradiation apparatus, and a blanking aperture array chip provided with blanking electrodes to perform blanking deflection on beams in a multi charged particle beam is mounted on the mounting substrate. The mounting substrate includes an opening through which the multi charged particle beam passes, a plurality of control circuits that supply a control signal to the blanking electrodes for each of a plurality of areas into which the blanking aperture array chip is divided, and grounds, each of which is provided for a corresponding one of the plurality of control circuits and configured to supply a ground electrical potential to the corresponding control circuit. The grounds corresponding to the control circuits are electrically separated from each other.
