Problems solved by technology

[0003] The preparation method of probes has attracted much attention as a prerequisite for the application of probe technology, but the preparation of large-size (hundred micron) microsphere probes has not been extensively studied.
Large-size (hundred-micron-scale) microsphere probes can be used for mesoscopic micro-nano processing. At present, the probe materials used in this scale processing are relatively single, mostly diamond materials, and the preparation is difficult and expensive; and Due to the high brittleness of diamond, the needle tip is easily bifurcated during processing, which seriously restricts micro-nano processing at the mesoscopic scale.

Embodiment Construction

[0025] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] see figure 1 , a method for preparing microsphere probes based on microcantilever transfer, realized by the following steps:

[0027] S1. Place the microspheres and the adhesive on the first preset area and the second preset area of ​​the silicon wafer respectively, and place the silicon wafer on the sample stage.

[0028] In this embodiment, microspheres of appropriate material and size are selected according to requirements, placed on a predetermined microsphere placement area on the silicon wafer, and the adhesive is placed on another predetermined area on the silicon wafer.

[0029] In this embodiment, the material of the microspheres is not particularly limited, and the size can be changed in a large gradient range from nanometers to millimeters, and the best effect is especially when the radius of curvature is in the range of 50-500 μm. Pr...

Abstract

The invention provides a microsphere probe preparation method based on micro-cantilever transfer, and belongs to the technical field of micro-nano manufacturing. The preparation method is simple in process and low in cost, and can be used for preparing the microsphere probe for testing micro-nano processing or indentation mechanical properties and the like; flexible bonding of any granular material can be realized, and any granular material can be randomly matched with any receptor platform; the cantilever can serve as a transfer layer while transferring the microspheres, so that the contact area of the microspheres and the receptor platform is increased, and the contact pressure is further reduced to reduce the deformation of the receptor platform; accurate positioning of the microspheresat the tip of the receptor in the probe preparation process can be achieved through the micro-cantilever, and the situation that the small-size microspheres are completely soaked into glue and pollute the surface of the microsphere probe in the bonding process can be avoided.
