The neural device includes a nano-wire formed on a base formed on a first surface of a substrate, and an electrode pad formed on a second surface different from the first surface of the substrate and configured to output an electrical signal gained from a neural fiber through the nano-wire or apply a signal for an electric stimulus to the nano-wire. Therefore, it is possible to prevent the nano-wire from becoming embedded in an encapsulation and maximize a contact between the nano-wire and a nerve. ## Claims ### Claim 1 A neural device comprising: a nano-wire formed on a base which is formed on a first surface of a substrate; and an electrode pad formed on a second surface different from the first surface of the substrate, and configured to output an electrical signal gained from a neural fiber through the nano-wire or apply a signal for an electric stimulus to the nano-wire, wherein the second surface is a surface having an angle of 170° to 180° between a normal vector of the second surface and a normal vector of the first surface, and the nano-wire and the electrode pad are connected to each other using a through via-hole, and wherein the electrode pad is connected to the outside of the neural device through a touch ball. ### Claim 2 (depends on 1) The neural device according to claim 1, wherein the through via-hole is disposed outside of a CMOS region of the substrate. ### Claim 3 (depends on 2) The neural device according to claim 2, wherein the base comprises a through-hole connected to the through via-hole and a nano-wire support frame configured to support the nano-wire. ### Claim 4 (depends on 3) The neural device according to claim 3, wherein the nano-wire is formed by a catalyst disposed on the nano-wire support frame through a lithography process and a reactant supplied through a chemical vapor deposition (CVD) process and reacting with the catalyst. ### Claim 5 (depends on 3) The neural device according to claim 3, wherein the nano-wire is formed by etching a periphery of the nano-wire. ### Claim 6 A nano-wire probe device comprising: a touch ball electrically connected to an electrode pad to be connected to a device; and a nano-wire formed on a base which is formed on a substrate, wherein the electrode pad is on a side of the substrate and the base is on the opposite side of the substrate, and the nano-wire is configured to provide an electrical signal measured from a neural fiber to the device through the touch ball or apply an electrical stimulus on the basis of a signal applied from the device through the touch ball. ### Claim 7 (depends on 6) The nano-wire probe device according to claim 6, wherein the electrode pad and the nano-wire are connected to each other using a through via-hole. ### Claim 8 (depends on 7) The nano-wire probe device according to claim 7, wherein the base comprises a through-hole connected to the through via-hole and a nano-wire support frame configured to support the nano-wire. ### Claim 9 (depends on 8) The nano-wire probe device according to claim 8, wherein the nano-wire is formed by a catalyst disposed on the nano-wire support frame through a lithography process and a reactant supplied through a chemical vapor deposition (CVD) process and reacting with the catalyst. ### Claim 10 (depends on 8) The nano-wire probe device according to claim 8, wherein the nano-wire is formed by etching a periphery of the nano-wire.
