Systems and methods for manufacturing nano-electro-mechanical-system probes
Systems and methods for manufacturing multiple integrated tip probes for scanning probe microscopy. According to an embodiment is a microscope probe configured to analyze a sample, the microscope probe including: a movable probe tip including a terminal probe end; a first actuator configured to displace the movable probe tip along a first axis; and a detection component configured to detect motion of the movable probe tip in response to an applied signal; where the moveable probe tip comprises a metal layer affixed to a supporting layer, at least a portion of the metal layer at the terminal probe end extending past the supporting layer.
1. A microscope probe configured to analyze a sample, the microscope probe comprising:
a moveable probe tip comprising a metal layer affixed to a top surface of a supporting layer, the moveable probe tip further comprising a terminal probe end, at least a portion of the metal layer at the terminal probe end extending past the supporting layer in a plane parallel to a top surface of a fixed substrate; and
a bottom electrode, wherein along a direction perpendicular to the top surface of the fixed substrate the bottom electrode is disposed between the movable probe tip and the fixed substrate;
wherein the moveable probe tip is configured to be moveable relative to the top surface of the fixed substrate and in the plane parallel to the top surface of the fixed substrate and wherein the bottom electrode is configured to move the probe tip relative to the top surface of the fixed substrate and in a plane perpendicular to the top surface of the fixed substrate.
2. The microscope probe of claim 1 , wherein at least a portion of a bottom surface of the supporting layer is attached to a spacer, the spacer fixedly secured to the top surface of the fixed substrate.
3. The microscope probe of claim 1 , wherein at least a portion of the supporting layer extends past the fixed substrate.
4. The microscope probe of claim 1 , further comprising:
a first monolithically integrated actuator configured to displace the movable probe tip along a first axis; and
a monolithically integrated detection component configured to detect motion of the movable probe tip in response to an applied signal.
5. The microscope probe of claim 1 , wherein said metal layer is platinum, gold, tungsten, or nickel.
6. The microscope probe of claim 1 , wherein said supporting layer is silicon, silicon dioxide, or silicon nitride.
7. The microscope probe of claim 1 , wherein the microscope probe comprises a plurality of probe tips each comprising a terminal probe end, each of the plurality of probe tips further comprising a metal layer affixed to a supporting layer, at least a portion of the metal layer at the terminal probe ends extending past the supporting layer.
8. The microscope probe of claim 7 , further comprising an insulated interdigitated air-gap structure positioned between each of the plurality of probe tips.
