Abstract:
The present invention provides a probe for a scanning magnetic force microscope having a resolution sufficient to allow observation of a magnetic storage medium with 1200 kFCI or higher recording densities, a method for producing the probe, and a method for forming a ferromagnetic alloy film on a carbon nanotube. In the context of the present invention, the probe for a scanning magnetic force microscope comprises a carbon nanotube whose surface is at least in part coated with a ferromagnetic alloy film consisting of any one of a Co—Fe alloy and a Co—Ni alloy, wherein the arithmetic mean roughness (Ra 10 μm) of the surface of the ferromagnetic alloy film is controlled to 1.15 nm or less. A method for producing such probes for a scanning magnetic force microscope and a method for forming such a ferromagnetic alloy film on a carbon nanotube, so as to achieve such mean surface roughness by controlling the growth rate of the ferromagnetic alloy film within the range of 1.0 to 2.5 nm/min, is also disclosed.

Abstract:
An indentation is formed by thrusting a probe of a scanning probe microscope for processing, which has a vertical surface or a vertical ridge and is harder than sample material, into sample for measuring the indentation. A high-fidelity AFM observation is performed on the shape of the formed indentation with a thin probe with high aspect ratio, the direction of the vertical surface or the vertical ridge is inspected, and the angle error θ is stored. By rotating a sample stage by an angle corresponding to the measured mounting angle error θ of the probe, the mounting angle error of the probe is corrected in advance.

Abstract:
A scanning microscope probe in which a palladium covering film is formed on the surface of the protruding portion of a cantilever, and the base end portion of a nanotube is disposed in contact with the palladium covering film with the tip end portion of the nanotube protruding to the outside, thus allowing the tip end to be used as a probe needle end for detecting signals. A coating film is formed to cover all or part of the surface of this base end portion, and the nanotube is thus firmly fastened to the cantilever. Since the base end portion adheres tightly to the palladium covering film, both of them are electrically continuous. This palladium covering film allows, as an electrode film, the application of a voltage to the nanotube or the passage of an electric current through the nanotube, showing also good adhesion to the nanotube and cantilever.
Abstract:
There is provided a scanning probe microscope capable of simply and accurately confirming whether or not a sample shape satisfies specified conditions. A pseudo reference image Sref1 comprises a pair of reference line profiles Lref1 and Lref2 arranged apart form each other in parallel. An operator moves and rotates the position of the pseudo reference image Sref1 on a screen so that a sample shape line profile fits between the reference line profiles Lref1 and Lref2 of the pseudo reference image Sref1. If it is possible to fit the line profile of the sample shape between the reference line profiles Lref1 and Lref2, it is determined that the sample shape is in spec, while if it is not possible to fit the line profile of the sample shape between the reference line profiles Lref1 and Lref2, no matter how the pseudo reference image Sref1 is moved and rotated, it is determined that the sample shape is out of spec.
Abstract:
A method of correcting a defective portion of an exposure window in a lithography mask, such as an EPL mask, includes a first step of irradiating a defective portion of the exposure window using a charge particle beam to perform correction processing, and a second step of irradiating another portion of the exposure window with the charged particle beam to eliminate attached matter therefrom, the attached matter consisting of particles ejected from the defective portion of the exposure window as a result of irradiation with the charged particle beam during the first step. The first step and the second step are sequentially repeated N times, wherein N is an integer of 2 or more, to thereby reduce the time needed for eliminating the attached matter.
