    摘要: The present invention provides a polishing fluid composition which can effectively polish a surface of a semiconductor silicon wafer or a surface of a film comprising silicon to be formed on silicon wafers with a markedly reduced amount of colloidal silica to be used as abrasives, or a polishing fluid composition which is particularly useful for a polishing step after removal of an oxide layer in a two-step polishing method. The former polishing fluid composition comprises an alkaline suspension which contains a water-soluble silicic acid component, colloidal silica and an alkaline component, and which has a pH value of 8.5 to 13. Meanwhile, the latter polishing fluid composition comprises an alkaline solution which contains a water-soluble silicic acid component and an alkaline component, and which has a pH value of 8.5 to 13; and is substantially free of abrasive particles.

A plurality of motherboard connection terminals are disposed to correspond to the openings. The motherboard connection terminals are primarily comprised of a copper layer, and peripheral portions of terminal outer surfaces thereof are covered by the outermost resin insulation layer. A dissimilar metal layer made of at least one metal which is lower in etching rate than copper is formed between an inner main surface of the outermost resin insulation layer and peripheral portions of the terminal outer surfaces.

    摘要: Provided are a conveying jig, a method of manufacturing the conveying jig, and a method of heat-treating metal rings using the conveying jig. The conveying jig is provided with a base and ten holding shafts raised from the base. Ridges and grooves are alternatively provided in the side wall of each holding shaft. The metal rings are held in position by being engaged in the grooves in the holding shafts. The space enclosed within the holding shafts is communicated with the atmosphere, and this allows, when the metal rings held by the conveying jig are subjected to heat treatment in a heat treatment furnace, an atmospheric gas to circulate in the space enclosed within the holding shafts.
