摘要:
In order to provide a scanning probe microscope capable of measuring with high throughput distribution information relating to local characteristics of a sample concurrently with accurate three-dimensional shape information of the sample without damaging the sample, the speed of approach to each measurement location is increased by controlling the approach of the sample and probe by the provision of a high-sensitivity proximity sensor of the optical type. Also, additional information relating to the distribution of material quality on the sample can be obtained without lowering the scanning speed by: applying a voltage to the probe, or measuring the response on vibrating the probe, or detecting the local optical intensity of the sample surface concurrently with obtaining sample height data and concurrently with the contact period with the sample, whilst ensuring that the probe is not dragged over the sample, by bringing the probe into contact with the sample intermittently.

Disclosed is a measurement method of a scanning probe microscope based upon a measurement method of a scanning probe microscope for observing a shape and an optical property of a sample by exciting near-field light, scanning relative positions of the near-field light and the sample and detecting scattered light by the sample of the near-field light and having a characteristic that the near-field light is modulated to periodically vary the relative positions of the near-field light and the sample and that a frequency of modulation applied to the near-field light and an interference signal generated at a frequency for varying the relative positions of the near-field light and the sample are selectively extracted.

In measuring the displacement of an object using the phase-shifting light interference, since three beam splitters were used for generating the four phase-shifting optical paths, an interferometer was increased in size, whereby the application objects were limited. Also, to solve an essential problem that if there is a disturbance such as a temperature distribution, a humidity distribution, an air pressure distribution, a density distribution or an air flow change on the phase-shifting optical paths, a measurement error occurs, the four phase-shifting optical paths are produced spatially in parallel by combining a four division prism with a photonic crystal λ/4 element and a photonic crystal polarizing element arranged like an array, constructing a small light interference displacement sensor in the invention, whereby the application objects are expanded, and the microscopic displacement or surface roughness of the object can be measured at a resolution of sub nanometer or less and with high reproducibility without influence of the disturbance.

In a scanning probe microscope, a nanotube and metal nano-particles are combined together to configure a plasmon-enhanced near-field probe having an optical resolution on the order of nanometers as a measuring probe in which a metal structure is embedded, and this plasmon-enhanced near-field probe is installed in a highly-efficient plasmon exciting unit to repeat approaching to and retracting from each measuring point on a sample with a low contact force, so that optical information and profile information of the surface of the sample are measured with a resolution on the order of nanometers, a high S/N ratio, and high reproducibility without damaging both of the probe and the sample.

In a method and an apparatus for inspecting a thermally assisted magnetic recording head element, a specimen is mounted on a table movable in a plane of a scanning probe microscope device, evanescent light is generated from a portion of light emission of evanescent light of the specimen, scattered light of the evanescent light is detected by moving the table in the plane while a cantilever of the scanning probe microscope having a probe is vertically vibrated in the vicinity of a surface of the specimen, and an intensity distribution of the evanescent light emitted from the portion of light emission of evanescent light or a surface profile of the portion of light emission of evanescent light of the specimen is inspected using position information of generation of the evanescent light based on the detected scattered light.

Optical information and topographic information of the surface of a sample are measured at a nanometer-order resolution and with high reproducibility without damaging a probe and the sample by combining a nanometer-order cylindrical structure with a nanometer-order microstructure to form a plasmon intensifying near-field probe having a nanometer-order optical resolution and by repeating approach/retreat of the probe to/from each measurement point on the sample at a low contact force.
