  • Patent number: 6750447
    Abstract: A method and apparatus used to calibrate high-resolution electron microscopes where a single standard provides multiple samples, each having a different atomic structure, permits rapid accurate calibration of the entire range of magnifications. The different atomic structure dimensions possess known reference measurement data. The S/TEM is adjusted to focus onto the crystal lattice structure of each sample in a selected sequence. Measurements of these lattice spacings are compared to known dimensions. If S/TEM measurements do not agree with the lattice spacing dimensions, the S/TEM magnification is adjusted to reflect known dimensions. Typical standard exchange and associated processing steps are eliminated by the use of the single standard comprising of a plurality of samples.

  • Patent number: 6708574
    Abstract: A semiconductor manufacturing automation method for analyzing a patterned feature formed on a semiconductor layer is disclosed. At least one patterned feature is scanned to generate an amplitude modulated waveform signal of the line and neighboring space characteristics. Signal processing is automatically performed on this waveform by an in-line computational source to extract known patterned features based on the profile of the amplitude modulated waveform signal. The extracted waveform segments are subjected to known geometric shapes to determine if the waveform indicates a normal or abnormal patterned feature on a semiconductor layer.

  • Patent number: 6633032
    Abstract: The present invention relates to a device for testing particles for composition and concentration. The device includes a particle counter, a collector screen, and a mass spectrometer. In one embodiment, the collector screen is positioned to receive particles received by the particle counter, and the mass spectrometer is positioned to receive counted particles retained on the collector screen.

  • Patent number: 6569690
    Abstract: Method for fabricating a structure. According to an exemplary embodiment, a structure is made by forming a layer of removable material with a first surface spaced a part from a second surface. The first surface is formed along a first region from which the material is removable. The first surface is altered by removal of material from the layer. Removed material from the first surface is monitored to detect fluctuations in a variable of composition in the layer, and removal of material from the first surface is terminated when the composition of monitored material meets a predetermined criterion. In an alternate embodiment a variable characteristic is imparted to a layer of material as a function of layer thickness and an operation is performed on the layer resulting in removal of material. Samples of removed material are monitored for variation in the characteristic and the operation is modified when a variation conforms with a criterion.

  • Patent number: 6405584
    Abstract: A scanning probe microscope includes a sensor head adjacent a stage for holding a sample, a scanning actuator for positioning the sensor head relative to the sample, and a probe carried by the sensor head. The probe preferably includes a base connected to the sensor head, a shank extending from the base at an angle offset from perpendicular to the base, and a tip connected to a distal end of the shank for contacting the sample. The angle is preferably in a range of 5 to 20°. The tip is preferably laterally offset from the base to permit viewing of the tip without interference from the shank and the base. Thus, the location of the probe tip relative to the sample may be more easily determined.

  • Publication number: 20020062572
    Abstract: A method of characterizing the shape of a probe element for a scanning probe microscope including using two test pattern surfaces of known configuration, the first surface having a pointed wedge-shaped tip and the second surface having an hour-glass type cross-section, wherein the surfaces are scanned to generate scan lines having curved transition zones that are geometrically matched in order to generate a probe characteristic representation curve, wherein the probe characteristic representation curve is a graphic representation of the shape of the tip of the probe.

  • Patent number: 5804460
    Abstract: Illustratively, the present invention includes a method of integrated circuit manufacturing which includes forming a raised topological feature upon a first substrate. A portion of the raised feature is removed, thereby exposing a cross sectional view of the raised feature with the substrate remaining substantially undamaged. The cross sectional view has a critical dimension. The critical dimension of the cross sectional view is measured using a first measuring instrument. Then the critical dimension is measured using a second measuring instrument. The measurements of the first and second measuring instruments are correlated. Then, using the second measuring instrument, raised features via plurality of second substrates are measured.
