Abstract:
1. A semiconductor device configured to control discharge of a liquid, the device comprising: a power supply terminal; a ground terminal; a plurality of driving portions arranged along a straight line between the power supply terminal and the ground terminal and configured to operate to discharge a liquid; a power supply line extending parallel to the straight line from the power supply terminal and configured to supply a power supply voltage to the plurality of driving portions; and a ground line extending parallel to the straight line from the ground terminal and configured to supply a ground voltage to the plurality of driving portions, wherein a width of the power supply line in a direction perpendicular to the straight line decreases away from the power supply terminal within a range in which the plurality of driving portions are arranged, and a width of the ground line in the direction decreases away from the ground terminal within the range.
