Coated active cantilever probes for use in topography imaging in opaque liquid environments, and methods of performing topography imaging

Active cantilever probes having a thin coating incorporated into their design are disclosed. The probes can be operated in opaque and/or chemically harsh environments without the need of a light source or optical system and without being significantly negatively impacted by corrosion. The probes include a substrate that has a cantilever, a thermomechanical actuator associated with the cantilever, a piezoresistive stress sensor disposed on the cantilever, and a thin coating disposed on the cantilever and the piezoresistive stress sensor. The coating is bonded to the substrate, is thermally conductive, and has a low thermal resistance. Further, the thin coating is configured to have little to no impact on one or more of a mass of the active probe, a residual stress of the cantilever, or a stiffness of the active probe. Techniques for performing topography and making other measurements in an opaque and/or chemically harsh environment are also provided.

SAMPLE CONTAINER MOUNTING MEMBER AND SAMPLE CONTAINER SEALING METHOD
20190353680 · 2019-11-21 ·

A holding member, a sample container, and a mounting member are used in a scanning probe microscope. The mounting member is made of an elastically deformable material such as a rubber material. The mounting member includes an annular main body. When the mounting member is mounted on the holding member and the sample container, the holding member is inserted into the sample container while the main body of the mounting member is elastically deformed along an outer circumferential surface of the sample container. One end of the mounting member is detached from the outer circumferential surface of the sample container, and brought into close contact with an outer circumferential surface of the holding member. When the holding member and the sample container are relatively moved, the main body of the mounting member is elastically deformed.

SCANNING PROBE MICROSCOPE AND CANTILEVER MOVING METHOD
20190317124 · 2019-10-17 ·

When a liquid surface is detected based on a detection signal from a photodetector during the approaching operation, a photodetector movement processor moves the photodetector to a position where reflected light from a cantilever is incident with the cantilever being in liquid. When the reflected light from the cantilever is incident on the photodetector during the approaching operation continued after the movement of the photodetector by the photodetector movement processor, an optical axis adjustment processor adjusts an optical axis of the reflected light incident on the photodetector. When a surface of a solid sample is detected based on a detection signal from the photodetector during the approaching operation continued after the adjustment of the optical axis by the optical axis adjustment processor, an approaching processor stops the approaching operation.

Sample holder, fixing member and method for fixing sample
10354833 · 2019-07-16 · ·

A sample holder includes a sample container and a fixing member. The fixing member is inserted into the sample container in a state in which a sample is placed, and fixes the sample by sandwiching the sample between the fixing member and a bottom surface of the sample container. At this time, a peripheral edge portion of the fixing member is elastically deformed by being inserted into the sample container, and the fixing member sandwiches the sample by its elastic force. Therefore, even when the sample is placed in the sample container in the state of being immersed in a liquid, the sample can be held in a stable state by the fixing member.
