Problems solved by technology

[0004] In the ordinary device for making scanning tunneling microscope probes, it is difficult to realize the verticality of the short probe rod by the connection structure of the fixed probe rod. Generally, it is necessary to use an instrument to adjust the verticality of the probe axis through the upper adjustment frame or the connection structure of the fixed probe rod. degree, and it is difficult to adjust the verticality of the probe axis; the probe axis is not vertical, which affects the needle tip of the probe on the probe axis and affects the quality of the probe tip

Abstract

The invention discloses a connecting structure for vertically fixing a probe rod and a probe rod fixing method. The connecting structure comprises a conducting plate (5), wherein a magnet (18) is adsorbed at the upper side of the conducting plate (5); the conducting plate (5) is connected with an upper regulating frame (4); the lower surface of the conducting plate (5) is a plane; conducting glue (19) is coated on the lower surface of the conducting plate (5). The method comprises the following steps of 1, manufacturing the probe rod with one sharp and long end; 2, manufacturing a magnetic probe rod with one sharp and long end; 3, uniformly coating the conducting glue on the lower surface of the conducting plate; 4, vertically fixing the magnetic probe rod with one sharp and long end on the lower surface of the conducting plate. The connecting structure disclosed by the invention solves the problems that the connecting structure for fixing the probe rod in the prior art is difficult to realize the verticality of a short probe; an external instrument is needed; the axial line perpendicularity of the probe is regulated through the upper regulating frame or the connecting structure for fixing the probe rod; the regulation of the axial line perpendicularity of the probe is difficult; when the axial line of the probe is not perpendicular, the pinpoint of the probe on the axial line of the probe is influenced; the pinpoint manufacturing quality of the probe is influenced.
