Abstract: Methods and systems for calibrating the location of x-ray beam incidence onto a specimen in an x-ray scatterometry metrology system are described herein. The precise location of incidence of the illumination beam on the surface of the wafer is determined based on occlusion of the illumination beam by two or more occlusion elements. The center of the illumination beam is determined based on measured values of transmitted flux and a model of the interaction of the beam 
with each occlusion element. The position of the axis of rotation orienting a wafer over a range of angles of incidence is adjusted to align with the surface of wafer and intersect the illumination beam at the measurement location. A precise offset value between the normal angle of incidence of the illumination beam relative to the wafer surface and the zero angle of incidence as measured by the specimen positioning system is determined.

Abstract: [Problem] To provide a method for removing metallurgical fumes from a snout in consecutive molten plating facilities, and a device for removing the metallurgical fumes from a snout, said device being capable of reliably removing from the snout metallurgical fumes which cause non-plating, without heating the outer wall of the snout. [Solution] By supplying a heated inert gas to the inside of a snout (10) formed between an outlet of a consecutive annealing furnace and a molten metal plating tank and discharging a gas having a flow rate that is greater than an amount of air supply gas while maintaining the ambient temperature of the inside of the snout and the temperature of the inner wall of the snout, a gas flow is formed from the consecutive annealing furnace toward the surface of the molten metal plating tank. It is therefore possible to prevent quality defects caused by the metallurgical fumes generated from a molten metal surface condensing and depositing on the inner wall of the snout or the inner wall of the consecutive annealing furnace or dropping and attaching to a steel sheet.
