  • Patent number: 7166840
    Abstract: A method for determining a depression/protrusion, especially of a line and space pattern formed on a sample, and an apparatus therefor. A charged particle beam is scanned with its direction being inclined to the original optical axis of the charged particle beam or a sample stage is inclined, broadening of a detected signal in a line scanning direction of the charged particle beam is measured, the broadening is compared with that when the charged particle beam is scanned with its direction being parallel to the original optical axis of the charged particle beam, and a depression/protrusion of the scanned portion is determined on the basis of increase/decrease of the broadening.

  • Patent number: 7164127
    Abstract: The present invention relates to a CDSEM (scanning electron microscope) capable of evaluating and presenting the measurement repeatability as a tool with a high degree of accuracy without being influenced by fluctuations in micro-minute shape that tend to increase with the microminiaturization of semiconductor patterns, and to a method for evaluating accuracy of repeated measurement using the scanning electron microscope. There is provided a function whereby when measuring a plurality of times the same part to be measured, by making use of a micro-minute pattern shape such as the roughness included in the pattern, pattern matching with a roughness template image is performed to correct two-dimensional deviation in position of the part to be measured on an enlarged measurement image acquired, and then an enlarged measurement area image is extracted and acquired. This makes it possible to eliminate variation in measurements caused by the micro-minute pattern shape.

  • Patent number: 7161163
    Abstract: The invention is directed to a method and an arrangement for plasma-based generation of soft x-radiation, particularly for the generation of extreme ultraviolet (EUV) radiation. The object of the invention, to find a novel possibility for providing a target for a plasma-based radiation source which permits a reduction in the heating and erosion of the nozzle and therefore permits an improved temperature control at the injection device, is met according to the invention in that a closure device is arranged between the target nozzle and the interaction region which interrupts an opening for temporarily passing the target flow by mechanically moving elements, wherein at least a portion of the target flow that is provided in a reproducible manner is separated in order to interact with the energy beam only during those time intervals in which an optical transmission from the interaction region to the target nozzle is prevented by the closure device.

  • Patent number: 7154108
    Abstract: A particle therapy system capable of measuring energy of a charged particle beam even during irradiation of the charged particle beam is provided. A beam delivery (irradiation) system comprises a block collimator constituted by a pair of collimator members, and an energy detector mounted to one of the collimator members to be disposed on the upstream side thereof. When the pair of collimator members are moved in directions away from each other, a beam passage is formed between them. The energy detector constitutes an energy measuring device together with a signal processing unit. A part of the ion beam having reached the interior of the irradiation nozzle is irradiated to a patient through the beam passage. When a part of the remaining ion beam enters the energy detector, electric charges generate in the energy detector. The signal processing unit determines energy of the ion beam based on a position within the energy detector at which electric charges have generated in maximum amount.

  • Patent number: 7154086
    Abstract: A reflectron lens and method are provided. The reflectron lens comprises a tube having a continuous conductive surface along the length of the tube for providing an electric field interior to the tube that varies in strength along the length of the tube. The tube may comprise glass, and in particular, a glass comprising metal ions, such as lead, which may be reduced to form the conductive surface. The method includes a step of introducing a beam of ions into a first end of a dielectric tube having a continuous conductive surface along the length of the tube. The method further includes a step of applying an electric potential across the tube to create an electric field gradient that varies in strength along the length of the tube so the electric field deflects the ions to cause the ions to exit the tube through the first end of the tube.

  • Patent number: 7145134
    Abstract: A detection scheme for time-of-flight mass spectrometers is described that extends the dynamic range of spectrometers that use counting techniques while avoiding the problems of crosstalk. It is well known that a multiple anode detector capable of detecting different fractions of the incoming particles may be used to increase the dynamic range of a TOFMS system. However, crosstalk between the anodes limits the amount by which the dynamic range may be increased. The present invention overcomes limitations imposed by crosstalk by using either a secondary amplification stage or by using different primary amplification stages.

  • Patent number: 7135692
    Abstract: A lithographic apparatus is disclosed. The lithographic apparatus includes an illumination system that provides a beam of radiation, and a support structure that supports a patterning structure. The patterning structure is configured to impart the beam of radiation with a pattern in its cross-section. The apparatus also includes a substrate support that supports a substrate, and a projection system that projects the patterned beam onto a target portion of the substrate. The illumination system includes a radiation-production system that produces extreme ultra-violet radiation, and a radiation-collection system that collects extreme ultra-violet radiation. Particles that are produced as a by-product of extreme ultra-violet radiation production move substantially in a particle-movement direction. The radiation-collection system is arranged to collect extreme ultra-violet radiation which radiates in a collection-direction, which is substantially different from the particle-movement direction.

  • Patent number: 7129486
    Abstract: The invention relates to a method for creating the image of a sample surface to be analyzed, with a resolution which is better than 1 ?m laterally in relation to the sample surface and better than 100 nm vertically in relation to said surface. According to the invention, the surface is scanned on a point-by-point basis by a scanning probe, the distance between the scanning probe and the sample surface at each scanning point being periodically modulated, in such a way that a force-time curve of the probe is produced for this point. The force-time curve is recorded at each scanning point, digitized using an A/D converter, evaluated online in real-time and stored, together with the entire data stream, in a first area of a memory device.

  • Patent number: 7126112
    Abstract: A compact vacuum chamber gives electric and optical access to a microchip, which is part of the chamber. The main use of the microchip is to confine, cool and manipulate cold atoms (atom chip). The main new feature is that the microchip forms one wall of a vacuum cell. This makes the chamber compact and lightweight, provides large optical access combined with small overall size, eliminates in-vacuum cabling, and makes the back surface of the chip accessible from the outside (e.g., for cooling and/or additional field-producing elements).

  • Patent number: 7122815
    Abstract: An emitting source capable of radiating substantial energy in the near infrared spectrum and suitable for use in non-dispersive infrared gas analyzers or other devices is described. Operation can be steady state (DC) or pulsed at high frequency with excellent modulation characteristics. The device consists of a tungsten filament mounted across the pins of a small transistor outline header and centered at the focal point of a parabolic or other shaped reflector. The header assembly is enclosed by a resistance-welded cap and window assembly having a specially sealed sapphire or other suitable IR transmissive window. Fundamental to the operation of the inventive IR emitter is the incorporation of a getter within the header package configured to prevent oxidation degradation of the tungsten filament. An inert gas backfill limits filament evaporation and further extends apparatus lifetime.
