Abstract:
PURPOSE: A probe of a scanning probe microscope(SPM) having a field-effect-transistor(FET) channel structure is provided to form a structure composed of a source, a channel and a drain, by etching a semiconductor substrate such as a single crystal silicon wafer to fabricate a probe structure, and by performing a doping process regarding an inclined etch surface of a tip portion at the end of the probe structure. CONSTITUTION: A probe(210) of a bar type is composed of a semiconductor. The first impurity is doped to a central inclined surface of a V-shaped tip at the end portion of the probe to form a channel region. The second impurity is doped to both inclined surfaces of the V-shaped tip of the end portion of the probe with the channel region as a center.

Abstract:
PURPOSE: A small and high density data storage apparatus using a probe is provided to arrange the probe to be crossed with an arm, and to perform a high density information recording via an entire storage medium area by using actuation of a short period. CONSTITUTION: An information storage medium is rotated. Cantilevers have probes(1,2,3) recording information in the information storage medium or reading the information. Arms(4) are crossed each other in order that the cantilevers correspond to each track(6,9,10) of the information storage medium, and operate the probes(1,2,3) and the information storage medium. The arms(4) are radially arranged on the basis of a center of the information storage medium. An interval controller controls intervals between the cantilevers and the information storage medium. A sensor reads bending operations of the cantilevers. Actuators(5) move each arm(4). A control circuit controls movements of the actuators(5).
Abstract:
The method having no floating point multifier obtains the co- ordinates (x,y) of a second memory where the rotated image will be recorded, by sequentially scanning a first memory where the M x N original image is recorded. The increments of X and Y corresp. to a rotation angle theta are added repeatedly. The image element data of (x,y) of the first memory are transmitted to the coordinates of the second memory with one-to-one correspondence.
