Patent Number: 
Section: claims

1. A scanning probe microscope (SPM) comprising:a first scanner that has a probe carrier holder, and changes a position of the probe carrier holder along a straight line;a second scanner that is decoupled from the first scanner and changes a position of a sample within a plane; anda tray configured to store a spare probe carrier and a spare probe attached to the spare probe carrier,wherein the probe carrier holder includes a plurality of protrusions that are configured for engagement with corresponding holes formed on the spare probe carrier. 2. The SPM of claim 1, further comprising:a probe carrier and a probe attached to the probe carrier,wherein the probe carrier can be attached to the probe carrier holder and detached from the probe carrier holder, and includes a plurality of holes corresponding to the protrusions of the probe carrier holder. 3. The SPM of claim 2, wherein the probe carrier is formed of metal. 4. The SPM of claim 1, wherein the tray includes a plurality of protrusions. 5. The SPM of claim 4, further comprising:a probe carrier and a probe attached to the probe carrier,wherein the probe carrier can be attached to the probe carrier holder and detached from the probe carrier holder, and includes a plurality of holes corresponding to the protrusions of the probe carrier holder and to the protrusions of the tray. 6. The SPM of claim 4, wherein the probe carrier is formed of metal. 7. The SPM of claim 1, wherein the probe carrier holder is formed of a permanent magnet or an electromagnet, includes a portion formed of a permanent magnet or an electromagnet, or includes a vacuum chuck. 8. The SPM of claim 1, wherein the tray is formed of a permanent magnet or an electromagnet, or includes a portion formed of a permanent magnet or an electromagnet. 9. The SPM of claim 1, wherein the probe carrier holder includes three protrusions that are hemispherical. 10. A scanning probe microscope (SPM) comprising:a first scanner that has a probe carrier holder, and changes a position of the probe carrier holder along a straight line;a second scanner that is decoupled from the first scanner and changes a position of a sample within a plane; anda tray configured to store a spare probe carrier and a spare probe attached to the spare probe carrier,wherein the probe carrier holder includes a plurality of protrusions that are configured for engagement with corresponding recesses formed on the spare probe carrier. 11. The SPM of claim 10, further comprising:a probe carrier and a probe attached to the probe carrier,wherein the probe carrier can be attached to the probe carrier holder and detached from the probe carrier holder, and includes a plurality of recesses corresponding to the protrusions of the probe carrier holder. 12. The SPM of claim 11, wherein the probe carrier is formed of metal. 13. The SPM of claim 10, wherein the tray includes a plurality of protrusions. 14. The SPM of claim 13, further comprising:a probe carrier and a probe attached to the probe carrier,wherein the probe carrier can be attached to the probe carrier holder and detached from the probe carrier holder, and includes a plurality of recesses corresponding to the protrusions of the probe carrier holder and to the protrusions of the tray. 15. The SPM of claim 13, wherein the probe carrier is formed of metal. 16. The SPM of claim 10, wherein the probe carrier holder is formed of a permanent magnet or an electromagnet, includes a portion formed of a permanent magnet or an electromagnet, or includes a vacuum chuck. 17. The SPM of claim 10, wherein the tray is formed of a permanent magnet or an electromagnet, or includes a portion formed of a permanent magnet or an electromagnet. 18. The SPM of claim 10, wherein the probe carrier holder includes three protrusions that are hemispherical. 19. A scanning probe microscope (SPM) comprising:a tray configured to store a plurality of probe carriers,a first scanner that changes a position of a probe carrier that is attached thereto along a straight line;a second scanner that is decoupled from the first scanner and changes a position of a sample within a plane; andwherein the probe carriers each have female engagement portions that are configured to mate with male engagement portions disposed on the first scanner and the tray. 20. The SPM of claim 19, wherein the female engagement portions are holes or recesses and the male engagement portions are hemispherical projections.
