Abstract

The present invention relates to an atomic force microscope probe device and its making method. It includes a probe seat, a cantilever which is fixed on the probe seat and has at least a tail end on which a probe point can be set and a carbon nano tube which is set on the tail end of said cantilever and used as probe point, in which the top portion of said probe cantilever tail end is formed into a plane with hole, and said carbon nano tube can be grown out from said hole which is basically perpendicular to said plane.

Description

【Technical field】 [0001] The invention relates to an atomic force microscope (Atomic Force Microscopy, hereinafter referred to as AFM) probe device and a manufacturing method thereof, in particular to an atomic force microscope probe device using carbon nanotubes as needle tips and a manufacturing method thereof. 【Background technique】 [0002] In recent years, with the increase in density and integration of devices such as optical disks, magnetic recording, and semiconductors, the application range of AFM, which measures the surface morphology of samples with sub-nanometer precision, has been expanding. It works by exploiting the force-distance dependence between its probe and sample to obtain material surface structures and properties. A typical AFM has three imaging modes: contact, non-contact, and tapping. The probe is the core component of AFM, which is expensive and easily damaged. [0003] Taking advantage of the good elasticity and tip properties of carbon nanotube...
