    • An SPM based measuring technique for measuring surface features of a sample fits a curve to a family of feature edge points acquired as a result of an SPM scan of the surface feature. If two curves are fit on opposed edges of the feature of interest, the maximum or minimum distance between those curves can be determined to ascertain a dimension of interest such as a maximum via width, a minimum line width, etc, The scan is preferably a relatively low-resolution scan in the Y direction, typically having 8-12 scan profiles passing through the feature of interest low-resolution, which is about half that typically used by prior techniques. The low-resolution scan can be performed relatively rapidly and with high repeatability. Repeatability is also higher than with prior techniques, and the level of repeatability is relatively insensitive to the resolution in the Y direction. Using a low-resolution scan also significantly reduces tip wear and increases throughput when compared to high-resolution scans.
    • 用于测量样品表面特征的基于SPM的测量技术将曲线拟合成由于表面特征的SPM扫描而获得的特征边缘点族。 如果两条曲线拟合在感兴趣特征的相对边缘上,则可以确定这些曲线之间的最大或最小距离,以确定感兴趣的尺寸,例如最大通孔宽度,最小线宽等。扫描优选为 在Y方向上的相对较低分辨率的扫描通常具有通过感兴趣的低分辨率特征的8-12个扫描轮廓,其大约是现有技术通常使用的一半。 低分辨率扫描可以相对快速地进行并具有很高的重复性。 重复性也高于现有技术,重复性水平对Y方向的分辨率相对不敏感。 与高分辨率扫描相比,使用低分辨率扫描也显着降低了尖端磨损并提高了吞吐量。

    • A scanning probe microscope and a scanning method using the same are provided to prevent distortion of an image due to an alignment error of scanners. A position of a probe(100) is linearly changed by a first scanner(310), and a position of a sample(200) is linearly changed by a second scanner(320). An adjusting unit(400) adjusts a position of the first scanner or the second scanner, so that a plane formed by position variation of the sample is perpendicular to a straight line formed by position variation of the probe. The adjusting unit obtains a first shape of the sample along a straight line in the plane, obtains a second shape of the sample along the straight line, and adjusts the position of the first or second scanner according to a difference between the first or second shape and an average shape of the first and second shapes.

    • PURPOSE: An apparatus for detecting the position of an electrostatic XY stage using time division multiplexing is provided to apply an excitation signal having a phase difference to a stator of each axis of the electrostatic XY stage to detect a capacitance variation from a moving plate in time division, thereby detecting X- and Y-axes of the stage. CONSTITUTION: An apparatus for detecting the position of an electrostatic XY stage using time division multiplexing includes a stage(10) that constructs a differential capacitor among a moving plate for moving a recording medium, a rotor comb connected to the moving plate, and stator combs, and an amplifier(11) that is connected to the stage and outputs a position information value in time division mode. The apparatus further has a sample/hold unit(12) for sampling and holding time-division position information output from the amplifier according to a timing control signal, and a controller(14) that generates a control signal to allow sampling and holding to be performed at the point of time when the time-division position information of the amplifier reaches the maximum value, reads position information output from the sample/hold unit, and generates an excitation signal having a phase difference.
