Publication number: 20030142283Abstract: An illumination system and condenser for use in photolithography in the extreme ultraviolet wavelength region having a first non-imaging optic element collecting electromagnetic radiation from a source and creating a desired irradiance distribution and a second non-imaging optic element receiving the electromagnetic radiation from the first non-imaging optic element and redirecting and imaging the electromagnetic radiation. The electromagnetic radiation emanating from the second non-imaging optic element is suitable for being received by other conventional optical surfaces to provide a desired irradiance distribution with a desired angular distribution and desired shape. Facets are used to provide the desired illumination over the desired illumination field. Reflective facets may be placed on the second non-imaging optic, which can reduce the number of mirrors and increase efficiency.Type: ApplicationFiled: February 7, 2003Publication date: July 31, 2003Inventor: James P.

Publication number: 20030142286Abstract: A method of manufacturing a semiconductor device and an apparatus of automatically adjusting a semiconductor pattern can precisely correct a difference in the shape or position of a pattern exposed or formed in two exposure steps. A pattern measuring unit measures an offset between the first pattern and the second pattern in a pattern measuring step. Based on the information on the offset thus detected, the first pattern is adjusted in a first patterning step with a high degree of freedom in the next manufacturing step cycle of a semiconductor device to precisely align the shape or position of the first pattern with the second pattern in a second patterning step with a low degree of freedom.Type: ApplicationFiled: February 24, 2003Publication date: July 31, 2003Inventors: Naoyasu Adachi, Katsuya Suzuki, Masayuki Noguchi

Publication number: 20030142287Abstract: The present invention relates to a light-wave rangefinder using a pulse method, which can reduce a measurement error, in which a tuned amplifier converts an electric signal of a light receiving unit into a damped oscillation waveform and thereby an arithmetic processing means can calculate a distance from a measuring position to a reflecting object on the basis of the damped oscillation waveform of the tuned amplifier. An optical noise sampling unit samples an optical noise produced in the rangefinder; an optical-noise storage unit stores sampling data of the optical-noise sampling unit; an arithmetic processing means reduces a measurement error caused by an optical noise on the basis of the sampling data of the optical-noise storage unit; and thereby a distance, a measurement error of which is reduced, can be calculated.Type: ApplicationFiled: December 16, 2002Publication date: July 31, 2003Inventors: Masahiro Ohishi, Yoshikatsu Tokuda

Publication number: 20030142289Abstract: When utilized in a flow imaging instrument, calibration beads provide a known data source that can be employed in various self-diagnostic, calibration and quality metric applications for the both the optical system of the flow imaging instrument, as well as the flow cell of the flow imaging instrument. Such data can be used to determine point spread functions associated with an imaging system, to determine a sensitivity of an imaging system, and to determine a focal point of the imaging system. Imagery collected from calibration beads can be used to determine core size and stability and TDI/flow speed synchronization. Calibration beads can be beneficially employed to enable stable system operation, even when very low sample concentration, or very small sample sizes are to be analyzed.Type: ApplicationFiled: January 16, 2003Publication date: July 31, 2003Applicant: Amnis CorporationInventors: William E.

Publication number: 20030142290Abstract: A light beam from a light-emitting device is applied to a measurement object via a collimator lens and an object lens, and reflected light concentrated via the object lens among the reflected light from a light spot formed on the measurement object is split and concentrated by a beam splitter and a light-receiving lens. The reflected lights from the two regions inside the light spot located at a prescribed interval on a straight line parallel to the travel direction of the measurement object are made to pass separately through two pinholes, respectively, and the resulting reflected lights are respectively made incident on two light-receiving sections. Then, on the basis of the outputs of the two light-receiving sections, the travel speed and the quantity of movement of the measurement object are measured by an operating unit.Type: ApplicationFiled: January 31, 2003Publication date: July 31, 2003Inventors: Akifumi Yamaguchi, Hisakazu Sugiyama
