In a method of manufacturing a circuit substrate of the present invention, a first through hole is formed in a semiconductor substrate and a first insulating layer is formed on the entire surface of the semiconductor substrate, and then first wiring layers connected to each other via an outer through conducting portion provided on the inner surface of the first through hole are formed on both sides of the semiconductor substrate, and then a second insulating layer is formed which covers the first wiring layers on both sides of the semiconductor substrate and the outer through conducting portion on the inner surface of the first through hole, the second insulating layer has a structure in which a second through hole is provided in a central portion of the first through hole, and then second wiring layers connected to each other via an inner through conducting portion provided in the second through hole are formed on the second insulating layer on both sides of the semiconductor substrate.

An ice composition obtained by freezing a liquid containing, dissolved therein, hydrogen peroxide produced by electrolysis; and a method of food storage using the composition. Hydrogen peroxide has a lower rate of dissipation into the air and better suitability for long-term storage than ozone. Furthermore, since hydrogen peroxide is electrolytically produced, it eliminates the trouble of transportation, storage, and dissolution. When seawater is used as a feed water for electrolysis, the ice composition thus obtained has a higher cooling effect because it has a melting point lower than 0° C.

A method for manufacturing a magnetostrictive torque sensor device includes the steps of: providing a steering shaft or another such rotating shaft with two magnetostrictive parts endowed with magnetic anisotropy; disposing detection coils around the magnetostrictive parts to detect changes in magnetostrictive characteristics of the magnetostrictive parts; providing a detection circuit for bringing out detection signals from signals outputted from the detection coils; and adjusting a gain of a gain adjuster included in the detection circuit.

A test setup for testing a contactless digital rotary joint integrated in a device requiring data transmission between a rotating part and a stationary part, the rotary joint further comprises a transmitter and a receiver. The transmitter has a transmitter amplifier, which is coupled to a pair of transmission lines, which are terminated by a pair of terminations. The transmission lines are differential transmission lines comprising a pair of conductors which is driven by differential signals from the transmitter amplifier. The receiver has a receiver antenna comprising a pair of antenna sections which are differentially operated and feed a differential signal to the receiver amplifier. A transmitter ground and a receiver ground are coupled to a common mode signal generator generating a common mode signal. A data source is coupled to the transmitter amplifier feeding a test signal into the transmitter amplifier, and a data sink is coupled to the receiver amplifier for receiving the test signal and generating a test result value. Also disclosed is a method for adjusting a contactless data link integrated in a device requiring data transmission between a rotating part and a stationary part.

An antenna device includes a resin multilayer board in which a plurality of resin sheets are stacked, and a coil conductor provided in the resin multilayer board. A plurality of line portions of the coil conductor are provided on a lower surface of the resin sheet. When a magnetic material core is preliminarily pressure-bonded to the resin sheet, the magnetic material core is fractured along the line portions and cracks occur. Thus, the resin sheet with the magnetic material core in which the cracks have been formed is fully pressure-bonded together with the other resin sheets.

A via-filling material includes a polymer containing a repeating unit represented by wherein R1 one of hydrogen, fluorine, chlorine, bromine, and methyl group; R2 is one of hydrogen, a C1-3 alkyl group, and a C1-4 alkyl group in which the hydrogen is replaced by at least one of fluorine, chlorine, and bromine; and X is —C(═O)O— or —S(═O)2O—. This via-filling material does not generate deposits around an opening of a via hole during plasma etching and provides a semiconductor integrated circuit with high reliability, even when a trench wider than the via hole is formed by plasma etching around the via hole filled with the via-filling material.

A thin film magnetic head capable of shortening a manufacturing time and a method of manufacturing the same are provided. After forming a write gap layer by using a non-magnetic conductive material such as copper, a top pole is formed on the write gap layer by growing a plating film with the write gap layer used as a seed layer. Unlike the case where the write gap layer is formed by using a non-magnetic insulating material such as alumina, a step of newly forming a seed layer aside from the write gap layer and a step of selectively removing the newly formed seed layer become unnecessary. Therefore, the number of manufacturing processes is reduced, and the manufacturing time of the thin film magnetic head is shortened.

The present invention relates to a method for manufacturing a polycrystalline semiconductor film that can be used for a semiconductor device. In the method, an amorphous semiconductor film is irradiated with a femtosecond laser to be crystallized. By laser irradiation using a femtosecond laser, when an amorphous semiconductor film over which a cap film is formed is crystallized with a laser, it becomes possible to perform crystallization of the semiconductor film and removal of the cap film at the same time. Therefore, a step of removing the cap film in a later step can be omitted.
