A transparent article made of a resin and having on its surface the fine unevenness formed by direct transfer of ultrafine particles. An unevenness transfer substrate having the ultrafine particles deposited thereon as a monolayer by using a binder, with a water/oil repellent film formed on the ultrafine particle layer, is placed in a mold, then a sufficiently deaerated fluid plastic resin is cast into the mold and heated to cause curing, then the mold is removed, and the unevenness transfer substrate and the cured resin are separated from each other. Consequently, the fine unevenness formed by the ultrafine particles is transferred to the resin surface.

Semiconductor device chips manufacturing and inspecting method is disclosed in which a semiconductor wafer is cut into individual LSI chips. The LSI chips are rearranged and integrated into a predetermined number. The cut LSI chips are integrated in a jig having openings with a size commensurate with the dimensions of the LSI chip. At least one part of the jig having such openings has a coefficient of thermal expansion that is approximately equal to that of the LSI chips. The integrated predetermined number of chips are subjected to an inspection process in a subsequent inspection step thereby improving efficiency and reducing cost.
摘要:
A semiconductor inspection apparatus which is possible to inspect a plurality of semiconductor devices collectively at one time, which has conventionally been difficult because of precision or the like of probes. A method of manufacturing the semiconductor inspection apparatus comprises the steps of forming a cover film on a surface of the silicon substrate and forming a plurality of probes of a polygonal cone shape or a circular cone shape through etching after patterning by photolithography, after the cover film is removed, again forming a cover film on the surface of the silicon substrate and forming a beam or a diaphragm for each probe through etching after patterning by photolithography, after the cover film is removed, again forming a cover film on the surface of the silicon substrate and forming a through hole corresponding to the probe through etching after patterning by photolithography, and after the cover film is removed, forming an insulating film on the surface of the silicon substrate, forming a metal film on a surface of the insulating film, and forming a wiring lead through etching after patterning by photolithography.

A fluid mixer for mixing a first fluid and a second fluid includes an introducing component having a bore, a cylindrical component fitted into the bore of the introducing component and a mixing component having a conical recess and on which the introducing component and the cylindrical component are held. A first introducing flow path receives the first fluid and a first distributing flow path distributes the first fluid over the whole circumference of the cylindrical component. A second introducing flow path receives the second fluid. A second distributing flow path distributes the second fluid so that the first fluid and the second fluid are alternately arranged in an circumferential direction. A joining part joins together the first fluid and the second fluid fed with the fluids alternately arranged circumferentially.
