摘要： Control method and apparatus for positioning an X-ray stage which is movable in X and Y directions to move a semiconductor wafer, for example, in a stepper wherein a pattern formed in the mask is sequentially printed on the shot areas of a semiconductor wafer in a step-and-repeat manner. The X-Y stage is provided with a wafer chuck supported by means of a tilting stage to control the tilting of the wafer chuck relative to the X-Y plane. In order to detect the position of the wafer chuck in the X and Y directions, the inclination of a laser interferometer mirror provided integrally with the wafer chuck relative to the X-Y plane can be detected. By this, when a positioning error for the X-Y stage occurs due to the Abbe length, in the Z direction, between the wafer supporting surface of the wafer chuck and the point in the mirror at which the laser beam from the laser interferometer is incident and due to the pitching and rolling of the X-Y stage, the error is detected on the basis of the attitude change by the movement of the X-Y stage, and is corrected.

摘要： Provided is a method for manufacturing a solar cell element that can increase the film thickness for collector electrodes formed in a screen printing process and reduce the resistance value of the same as well as contribute to improvements in conversion efficiency. When a collector electrode for a solar cell element is formed by screen printing of a conductive paste, that screen-printing process is repeated a plurality of times. At this time, the squeegee speed during the second or later screen printing is faster than the squeegee speed during the first screen printing. The second and later screen printing is superimposed on the collector electrode printed the first time; therefore, the faster the squeegee speed is, the better the plate release is for the paste and foundation. The amount of paste applied increases, and the film for the collector electrode that is formed becomes thicker.

摘要： Disclosed is a solar cell having a silicon monocrystal substrate surface with a textured structure and, near the surface of said substrate, a damage layer reflecting the slice processing history from the time of manufacture of the silicon monocrystal substrate. The damage layer near the surface of the silicon monocrystal substrate is derived from the slice processing history at the time of manufacture of the substrate and functions as a gettering site, contributing to a longer lifetime of the substrate minority carriers. Thanks to this effect, the solar cell characteristics are dramatically increased. Further, new damage need be inflicted, and no additional work is required because damage from the slicing is used.

摘要： A casting roll having an outer periphery capable of being efficiently cooled is disclosed. The casting roll has a roll body on which side weirs abut, short tube-shaped supports each coaxially with and protruding from the roll body, a stub axle fitted into the support, a sleeve fitted over the support and a flange contiguous with the stub axle and abutting on the sleeve on a side away from the roll body. The roll body is formed with longitudinal cooling passages passing through the roll from one end to the other end of the roll as well as radial cooling passages each adjacent to a corresponding end of the roll and extending from an inner periphery of the roll to a corresponding longitudinal cooling passage. A plug is fitted into each end of the longitudinal cooling passages and abuts on the sleeve. With a distance between the longitudinal cooling passages and the outer periphery of the roll body being reduced as much as possible, cooling water is passed through a portion of the roll body.

摘要： An operation to acquire a strip with less thickness even if arcuate worn steps are formed on side weirs is disclosed. During an operation of a twin-roll casting machine with arcuate worn steps developing on side weirs due to rotational sliding contact of chilled rolls, the thickness of a steel strip from a nip is reduced, and the center-to-center distance between the rolls is increased with the side weirs in contact with ends of the rolls being displaced upward. This prevents interference of outer peripheries of the rolls with boundary surfaces adjacent to the arcuate worn steps of the side weirs.

摘要： Disclosed is a phosphorus paste for diffusion that is used in continuous printing of a phosphorus paste for diffusion on a substrate by screen printing. The phosphorus paste for diffusion does not undergo a significant influence of ambient humidity on viscosity and has no possibility of thickening even after a large number of times of continuous printing. The phosphorus paste for diffusion is coated on a substrate by screen printing for diffusion layer formation on the substrate. The phosphorus paste for diffusion includes a doping agent containing phosphorus as a dopant for the diffusion layer, a thixotropic agent containing an organic binder and a solid matter, and an organic solvent. The doping agent is an organic phosphorus compound.

摘要： A chimney has a lower portion substantially in the shape of a pyramid and an upper portion forming a cylindrical portion that extends with a predetermined dimension upwardly and is provided in a ceiling portion of a building of a coil yard that is used for temporary storage of the hot-rolled coil which is an intermediate iron and steel product acting as a high-temperature heat radiator that is manufactured using the hot-rolling equipment of an iron and steel mill. A power generating turbine is provided at a predetermined position in the cylindrical portion. An intake duct is provided on a lower end portion of the side walls of the building. Hot-rolled coils that are in a high-temperature condition after manufacture are successively imported into the coil yard and accumulated and stored until transfer to a subsequent processing step. An ascending airflow is generated by sequential heating of air introduced into the building from the intake duct using heat retained in the hot-rolled coils. The power generating turbines are rotated by the ascending airflow passing through the cylindrical portion of the chimney to thereby execute wind power generation. As a result, the heat retained in the high-temperature heat radiator manufactured by introduction of heat can be efficiently used.
