  • Patent number: 8756710
    Abstract: Cantilever probes are formed from a multilayer structure comprising an upper substrate, a lower substrate, an interior layer, a first separation layer, and a second separation layer, wherein the first separation layer is situated between the upper substrate and the interior layer, the second separation layer is situated between the lower substrate and the interior layer, and wherein the first and the second separation layers are differentially etchable with respect to the first and the second substrates, the interior layer. The upper substrate is a first device layer from which a probe tip is formed. The interior layer is a second device layer from which a cantilever arm is formed. The lower substrate is a handle layer from which a handle, or base portion, is formed. Patterning and etching processing of any layer is isolated from the other layers by the separation layers.

  • Patent number: 7584653
    Abstract: Dynamic nanomechanical analysis of a sample is performed by using a cantilever probe that interacts with the sample using a force applied across a wide range of frequencies that includes frequencies greater than 300 Hz. The motion of the cantilever probe is detected in response to the applied force over the range of frequencies and analyzed over at least a portion of the wide range of frequencies to determine a mechanical response of the sample, preferably including quality factor and modulus of the sample. The analysis of the motion of the cantilever probe is preferably performed in terms of amplitude, phase, and frequency of both the probe and the sample and preferably, where the applied force is analyzed to determine both a real and an imaginary modulus of a mechanical response of the sample. Preferably, the force is applied so as to produce a minimum of phase and amplitude response variation in the absence of the sample.
