摘要:
The present invention provides a multilayer wiring technology by which high adhesiveness and high insulation reliability between wirings are obtained, while maintaining effective low capacitance between wirings. A semiconductor device is characterized in that a first insulating film is an insulating film formed of at least one layer which contains a siloxane structure containing silicon, oxygen and carbon; the siloxane structure in the inner part of the first insulating film contains a larger number of carbon atoms than the number of silicon atoms; and a modified layer which containing a smaller number of carbon atoms and a larger number of oxygen atoms per unit volume than the inner part of the first insulating film is formed on at least one of an interface between the first insulating film and the metal and an interface between the first insulating film and a second insulating film.

A light emitting diode array in which, when viewed from the above, the shape of an almost square light emitting diode is square-chamfered or round-chamfered at the corners thereof in order to minimize light leakage at a reverse mesa surface to allow an electrode layer to surround the three directions of a light emitting unit, and part in the vicinity of the corner of the reverse mesa surface is extended up to a substrate unit to cover it. Accordingly, the light emitting diode array minimized in light leakage at the reverse mesa surface can be provided.

To suppress deterioration in reliability of wiring and to reduce effective dielectric constant of wiring. In a semiconductor device, copper-containing wirings are covered by barrier insulating films, and the barrier insulating films contain a component of an organic silica containing unsaturated hydrocarbon and amorphous carbon. The copper-containing wirings are covered by the barrier insulating films that contain a component that is in an organic silica structure containing unsaturated hydrocarbon and amorphous carbon. Accordingly, inter-wiring capacitance is reduced without deteriorating reliability of the copper-containing wiring, thereby realizing a high-speed LSI with low power consumption.

A treatment instrument for endoscope that is suitable for cutting submucosal layer in endoscopic submucosal dissection is provided, and the treatment instrument for endoscope has a treatment section at a distal end of an insertion section which is inserted in a body. The treatment section includes a conductor that is connected to a high-frequency source, and is configured to have a sandwich structure in which the conductor is sandwiched between a non-conductor on the distal end side thereof and a non-conductor on a proximal end side thereof. The conductor is formed to be exposed in a strip-shape at a side surface of the treatment section, and a lateral movement of the treatment section causes a cutting of a submucosal layer with the conductor to be performed.

A combination seal is attached to a bearing comprising a fixed element and a rotating element which rotate relative to each other, so as to seal an inner side and an outer side of the bearing. The combination seal is comprised of a seal ring and a slinger. The seal ring is comprised of a reinforcing ring and an elastic seal supported by the reinforcing ring. A leading end side of the elastic seal, supported by the reinforcing ring extending toward the slinger, is brought into contact with a surface of the slinger, which is opposite to the seal ring, when the combination seal is attached to the bearing. During a combining work process, when combining the seal ring and the slinger to form the combination seal, a seal lip does not turn over and the seal lip can be held toward a predetermined direction without using a specific jig during the combining work process and without being particularly careful during performance of the combining work process.

A vacuum deposition apparatus is used for deposit evaporated substance from evaporation sources (6a and 6b) on the desired position of a flexible substrate (1). While the flexible substrate (1) is carried using rollers in a vacuum, shutters (8a and 8b) are opened and closed to control the movement of the evaporated substance via openings. A film having a desired shape of pattern is formed on the flexible substrate (1) with higher controllability.

Provided is a method for producing a pigment, in particular, a metal phthalocyanine, in high yield and in a green process. The method has (1) a step of obtaining a solution mixture by mixing at least one type of compound serving as a raw material for a pigment with a solvent, and (2) a step of obtaining the pigment by reacting the compound while holding the solution mixture at not less than a temperature where a subcritical state or a supercritical state of the solvent occurs.

An encoder-equipped sealing device includes two seal members arranged to face opposite each other and each having a reinforcing ring with an L-shaped cross section. Each of the reinforcing rings has a cylindrical portion and a flange portion extending from one end of the cylindrical portion in a direction perpendicular to the cylindrical portion. One seal member includes an elastic seal formed in such a manner as to be supported by the reinforcing ring of this seal member, with the elastic seal extending toward the other seal member such that a seal portion is formed between the elastic seal and the other seal member. The other seal member includes an encoder on a side of the flange portion of the other seal member that is opposite a side facing the one seal member. The one seal member includes an elastic element formed in such a manner as to be supported by the flange portion of this seal member. The elastic element is formed on a side of the flange portion of the one seal member that is opposite a side facing the other seal member.
