Method of making thin film probe tip for atomic force microscopy
Abstract:
A probe for atomic force microscopy may be provided by depositing a thin film onto a wafer substrate and etching the substrate to leave the thin film behind in the form of a handle, a cantilever, and a probe tip in the cantilever. In some embodiments, a thin film substrate for the probe may be accomplished by forming the probe mold on a first wafer, bonding a second wafer onto the first wafer, and patterning out the second wafer to define the substrate for the probe on the first wafer. The thin film may be deposited onto the exposed portions of the first wafer. Thereafter, portions of the first and second wafers may be removed to leave behind the probe.
