A substrate surface inspection method inspects for a defect on a substrate including a plurality of materials on a surface thereof. The inspection method comprises: irradiating the surface of the substrate with an electron beam, a landing energy of the electron beam set such that a contrast between at least two types of materials of the plurality of materials is within a predetermined range; detecting electrons generated by the substrate to acquire a surface image of the substrate, with a pattern formed thereon from the at least two types of materials eliminated or weakened; and detecting the defect from the acquired surface image by detecting as the defect an object image having a contrast by which the object image can be distinguished from a background image in the surface image. Defects present on the substrate surface can be detected easily and precisely by using a cell inspection.

An automatic document feeder includes a separating and feeding unit which has a separating member and a paper feeding member coming into contact with the separating member at a predetermined separating pressure, and separates and feeds an original sheet by sheet from a bundle of originals placed on an original placing table; a conveying unit which conveys the original separated by the separating and feeding unit toward a scanning position; a separating pressure switching unit which applies and releases the separating pressure and which is controlled by a control unit to release the separating pressure after a leading edge of a preceding sheet of the original has passed through the separating and feeding unit and to apply the separating pressure before a sheet of original separated and fed next to the preceding sheet of original is fed from the bundle of original to the separating and feeding unit.

A plating method and apparatus for a substrate fills a metal, e.g., copper, into a fine interconnection pattern formed in a semiconductor substrate. The apparatus has a substrate holding portion 36 horizontally holding and rotating a substrate with its surface to be plated facing upward. A seal material 90 contacts a peripheral edge portion of the surface, sealing the portion in a watertight manner. A cathode electrode 88 passes an electric current upon contact with the substrate. A cathode portion 38 rotates integrally with the substrate holding portion 36. An electrode arm portion 30 is above the cathode portion 38 and movable horizontally and vertically and has an anode 98 face-down. Plating liquid is poured into a space between the surface to be plated and the anode 98 brought close to the surface to be plated. Thus, plating treatment and treatments incidental thereto can be performed by a single unit.

An artificial nipple can include a nipple body portion connected to a mounting structure that is configured for mounting the nipple on an infant feeding bottle 11. A mammary papilla leading end portion 140 can be disposed at the leading end portion of a mammary papilla portion 130 and have a leading end opening portion 141. The wall from the nipple body portion to the mammary papilla leading end portion is made of a soft material. The inner layer on the inner side of the wall is formed of a shape holding layer made of a material having a rigidity capable of holding the wall shape. The outer layer on the surface side of the wall is formed of a tongue abutting layer having a smooth face for allowing a peristalsis motion by a tongue. Between the shape holding layer and the tongue abutting layer there is disposed a deformation absorbing layer which is made of a material having a lower rigidity than that of the material of the shape holding layer and the tongue abutting layer. The deformation absorbing layer can be made thicker than the shape holding layer and the tongue abutting layer.
摘要:
The present invention relates to a semiconductor device and a method for manufacturing the same. The semiconductor device has an embedded interconnect structure in which an electric conductor, such as copper or silver, is embedded in fine recesses formed in a surface of a semiconductor substrate, and also has a protective film formed on surfaces of exposed interconnects that define the interconnect structure, to protect the interconnects. The protective film has a flattened surface.

A substrate processing apparatus fills a metal such as copper or the like in fine interconnection patterns or trenches defined in a semiconductor substrate. The substrate processing apparatus has a loading/unloading unit for placing a substrate cassette to allow a substrate to be loaded and unloaded, a substrate treating unit for treating a substrate, and a transfer robot for transferring a substrate between the loading/unloading unit and the substrate treating unit. The loading/unloading unit, the substrate treating unit, and the transfer robot are installed in a single facility. The loading/unloading unit has a rotary table which is horizontally rotatable for positioning the substrate cassette in a position to detect the substrate cassette placed in the loading/unloading unit and to remove the substrate from the substrate cassette with the transfer robot.

A holding unit holds a substrate to enable a surface of the substrate to be processed. The unit has a vacuum suction member that comes into contact with a peripheral portion of the surface of the substrate and sucks the substrate. A processing apparatus holds the wafer stably and allows an edge, a bevel portion and/or a back surface of the wafer to be processed.

A polishing apparatus for polishing a workpiece such as a semiconductor wafer has a turntable with a polishing surface, and a top ring for holding a workpiece and pressing the workpiece against the polishing surface under a first pressing. The polishing apparatus has a pressurized fluid source for supplying pressurized fluid, and a plurality of openings provided in the holding surface of the top ring for ejecting the pressurized fluid supplied from the pressurized fluid source. A plurality of areas each having the openings are defined on the holding surface so that the pressurized fluid is selectively ejectable from the openings in the respective areas.
