Patent number: 6632348Abstract: A device and method for etching a wire to manufacture it into a tip for a scanning probe microscope or the like. The wire etching device generates a voltage signal for determining the level of a wire etching voltage, and applies the etching voltage of the level determined depending on the generated voltage signal to the wire to primarily etch it. The wire etching device measures the amount of etching current generated during the primary etching process and controls the level of the voltage signal according to the measured etching current amount so as to control the level of the etching voltage. Then, the device secondarily etches the wire with the level-controlled voltage signal. Therefore, the wire etching device can manufacture the tip while controlling its curvature radius and aspect ratio and reducing the amount of oxide on its surface.Type: GrantFiled: May 15, 2001Date of Patent: October 14, 2003Assignee: Korea Institute of Science and TechnologyInventors: Hyo Sok Ahn, Choong Hyun Kim, Doo In Kim

Patent number: 6441371Abstract: The present invention relates to a two-phase scanning method and apparatus for obtaining information necessary to analyze physical properties of materials using a scanning probe microscope. The scanning operation of the present invention is divided into two phases. First, in order to obtain information on a surface of a sample, a first scan is provided while the probe moves along the sample surface. Based upon results of the first scan, an imaginary line is defined on an average plane of the sample surface. Then, an imaginary plane, one side of which intersects the imaginary line and makes a predetermined angle with reference to the average plane, is defined over an area of interest on the sample surface. The probe is then positioned at a predetermined height on the imaginary inclined plane, and a second scan is provided during downward movement of the probe along the imaginary inclined plane.Type: GrantFiled: April 3, 2000Date of Patent: August 27, 2002Assignee: Korea Institute of Science and TechnologyInventors: Hyo-Sok Ahn, Choong Hyun Kim, Sergei A.
