Claim Text:
1. A nanowire field effect sensor comprising nanowires having a three-dimensional stacked structure, the nanowire field effect sensor comprising: a substrate for forming the nanowire field effect sensor; a source electrode formed by alternately stacking one or more semiconductor channel layers and sacrificial layers on one side of the substrate in a direction perpendicular to the substrate; a drain electrode formed by alternately stacking one or more semiconductor channel layers and sacrificial layers on another side of the substrate in a direction perpendicular to the substrate; one or more nanowires connected between the semiconductor channel layers of the source electrode and the semiconductor channel layers of the drain electrode and stacked in a direction perpendicular to the substrate; a channel made of a separate material through which a solution can flow and formed between a rate insulating layer of an outer surface of the nanowires and a submerged gate electrode formed on the substrate; and a detector material which is fixed to a side of the nanowires and reacts selectively with a target material introduced from an outside source.
