A semiconductor substrate with a groove is placed in a plasma generating reaction chamber. Silicon, oxygen and hydrogen containing gases are introduced into the reaction chamber as process gases. A ratio of a gas flow of the hydrogen containing gas except the silicon containing gas to a total gas flow of the silicon containing gas and the oxygen containing gas defines a first gas-flow ratio. A ratio of a gas flow of the oxygen containing gas to that of the silicon containing gas defines a second gas-flow ratio. The first and second gas-flow ratios establish a linear function for a critical condition. A cluster formation condition is set up by relatively increasing the first gas-flow ratio while relatively decreasing the second gas-flow ratio with respect to the critical condition. A cluster suppression condition is also set up by relatively decreasing the first gas-flow ratio while relatively increasing the second gas-flow ratio with respect to the critical condition. The process gases are supplied to the reaction chamber under the cluster formation condition and under the cluster suppression condition, alternately, to form an insulating film buried in the groove.

A progressive power lens belonging to a series of lenses according to the present invention is provided. If a first lens and a second lens randomly chosen from the series of progressive power lenses have a common spherical refractive power Sph [diopter] in the distance portions thereof, the Sph is greater than or equal to +1, and a base curve BCof the first lens is smaller than a base curve BCof the second lens, the first and second lenses satisfy a condition:

Progressive power lens

A method for manufacturing a metallic dental crown comprising making a model base out of a base formed on a tooth root in an oral cavity; capping only a top portion of the model base with a mold material for forming a dental crown occlusal portion which is made of plastic film and which has a shallow royal crown configuration; coating that area of an outer peripheral surface of the model base, which is not capped with the mold material for forming the dental crown occlusal portion, with wax to form a composite mold material for forming the dental crown integral with the mold material for forming the dental crown occlusal portion; and substitution molding the composite mold material for forming the dental crown with a metal material. A mold material for forming a dental crown occlusal portion used for manufacturing a metallic dental crown is also disclosed.

Method for manufacturing metallic dental crown and mold material for forming dental crown occlusal portion used for the method

A method for manufacturing a color filter colors a large number of filter elements on a substrate respectively in a predetermined color. A filter element is colored while an ink-jet head nozzle and the filter element are aligned. The method comprises a detection step of detecting the position of the filter element, a correction step of correcting a relative position of the filter element and a discharge nozzle for discharging coloring material, based on position information of the filter element detected at the detection step, so that the filter element and the discharge nozzle are aligned, and a coloring step of coloring the filter element by discharging the coloring material by the discharge nozzle.

Color filter, display device using color filter, apparatus comprising display device, ink-jet head, and color filter manufacturing method and apparatus
