Abstract:
A scanning probe system for determining electrical characteristics between two locations on a sample, the scanning probe system comprising:a stage having a surface for mounting the sample; a probe assembly including: a substrate, a first spring probe having a fixed end attached to the substrate, a curved central section bending away from the substrate, and a free end including a probe tip for contacting a first location of the sample, and a second spring probe having a fixed end attached to the substrate, a curved central section bending away from the substrate, and a free end including a probe tip for contacting a second location of the sample; and an electrical measurement device having a first terminal connected to the first spring probe, and a second terminal connected to the second spring probe, wherein the first and second spring probes comprise stress-engineered spring material films having an internal stress gradient.
