Abstract

A SERS unit comprises a substrate; an optical function part formed on the substrate, for generating surface-enhanced Raman scattering; and a package containing the optical function part in an inert space and configured to irreversibly expose the space.

Claims

1. A surface-enhanced Raman scattering unit comprising:

a handling board;

a substrate attached onto the handling board;

an optical function part constructed by a conductor layer covering a fine structure part formed on a front face of the substrate, for generating surface-enhanced Raman scattering; and

a package containing the substrate and the optical function part in a space and configured to irreversibly expose the space;

wherein a rear face of the substrate is secured to the handling board in the state where the rear face of the substrate opposes a surface of the handling board; and

wherein a thickness of the substrate is greater than a thickness of the conductor layer.

2. A surface-enhanced Raman scattering unit according to claim 1,

wherein the package has a sheet sealing an opening of the space;

and

wherein the package is configured to irreversibly expose the space when an end part of the sheet is held and lifted to the side opposite from the space.

3. A surface-enhanced Raman scattering unit according to claim 1,

wherein the handling board is provided with a hollow part so as to form a wall part extending in directions perpendicular to the thickness direction of the handling board.

4. A surface-enhanced Raman scattering unit according to claim 3,

wherein the hollow part is provided as multiple hollow parts.

5. A surface-enhanced Raman scattering unit according to claim 3,

wherein the space is a space within a first depression formed on a front face of the handling board;

wherein the hollow part is a second depression formed on a rear face of the handling board; and

wherein a bottom face of the second depression is located on the side of the front face of the handling board from a bottom face of the first depression.

6. A surface-enhanced Raman scattering unit according to claim 1,

wherein a part opposing the optical function part in the package is deflected to the side of the optical function part.

7. A surface-enhanced Raman scattering unit according to claim 1,

wherein a thickness of a part opposing the optical function part in the package is smaller than a thickness of the substrate.

8. A surface-enhanced Raman scattering unit according to claim 1,

wherein the package is separated from the optical function part and is in contact with an outer surface of the handling board.

9. A surface-enhanced Raman scattering unit according to claim 1,

wherein the package is configured to irreversibly expose the space in order to arrange a sample on the optical function part.

10. A surface-enhanced Raman scattering unit according to claim 1,

wherein the package is a cap attached onto the handling board.
