Patent ID: 7861316

Claim:
A microscope probe, the probe comprising: a coaxial tip and a coplanar waveguide formed on a silicon substrate, wherein the silicon substrate includes a probe support and a cantilever beam extending from the probe support; the coaxial tip comprising a tip shaft formed from the silicon substrate and extending from the silicon substrate near a first edge of the cantilever beam opposite the probe support; and a tip nib formed from the silicon substrate and extending from the tip shaft opposite the silicon substrate; wherein the tip shaft includes a first layer of a first conductive material formed over the silicon substrate, a second layer of an insulating material formed over the first layer, and a third layer of a second conductive material formed over the second layer; and further wherein the tip nib includes the first layer of the first conductive material formed over the silicon substrate and exposed from the second layer and the third layer of the tip shaft; and the coplanar waveguide comprising a center conductor formed from the first layer of the first conductive material and extending from the tip shaft along the cantilever beam and along the probe support; a first outer conductor formed from the second layer of the second conductive material and extending from the tip shaft along the cantilever beam and along the probe support; and a second outer conductor formed from the second layer of the second conductive material and extending from the tip shaft along the cantilever beam and along the probe support.
