摘要:
The present invention provides a method for fabricating a semiconductor device which initially performs chemical mechanical polishing with respect to a metal film made of copper formed on a semiconductor substrate to form wires composed of the metal film on the semiconductor substrate and subsequently removes a wire-to-wire bridge occurring during the formation of the wires and remaining on the semiconductor substrate to cause unneeded conduction between the wires adjacent to each other. The removal of the wire-to-wire bridge is performed by oxidizing the wire-to-wire bridge into a copper oxide by using an aqueous hydrogen peroxide and then dissolving the copper oxide by using an oxalic acid. This allows the removal of the wire-to-wire bridge without damaging the main bodies of the wires.

Provided is a curable resin composition which has excellent optical properties, heat resistance, transparency, low water absorbability, and mold release property in molding, and reduces the occurrence of a burr from a mold. Also provided are a cured product thereof and an optical material. The curable resin composition includes: a component (A): a soluble polyfunctional (meth)acrylic acid ester copolymer which is obtained by copolymerizing components including a monofunctional (meth)acrylic acid ester (a) having an alicyclic structure, a bifunctional (meth)acrylic acid ester (b), and 2,4-diphenyl-4-methyl-1-pentene (c), has a reactive (meth)acrylate group derived from (b) in a side chain and a structural unit derived from (c) at an end, has a Mw of 2,000 to 20,000, and is soluble in an organic solvent; a component (B): a polyfunctional (meth)acrylate; and a component (C): an initiator, in which the blending amounts (weight ratio) of the respective components are as follows: (B)/(A)=5 to 250/100, and (C)/[(B)+(A)]=0.1 to 10/100.

An optical fiber has an incident end on which light is incident, an emitting end from which the light is emitted, and an aperture provided in a core located at or near the emitting end. The aperture is formed by irradiating the core with an ultrashort pulsed laser beam having pulse widths of 10−15 seconds to 10−11 seconds.

An image forming apparatus includes a printhead, a carriage, one or more guide members, and a positioning mechanism. The printhead is mounted on the carriage. The one or more guide members support the carriage. The positioning mechanism includes an eccentric bearing and a rotation restrictor. The eccentric bearing is connected to each guide member and rotatable around a rotational axis offset from a guide member longitudinal axis to move the guide member relative to a substantially horizontal plane. The rotation restrictor defines a first point of contact with the eccentric bearing when the carriage is in a first operational position, and a second point of contact with the eccentric bearing when the carriage is in a second operational position. At least one of the first and second points of contact is displaceable with respect to the bearing rotational axis to modify the corresponding operational position of the carriage.

A printer includes a body, a cloth holder to hold a cloth thereon, a receiver to hold and move back and forth while holding the cloth holder partially within the body of the printer, and a printing unit to print an image on the cloth held by the cloth holder held on the receiver. The cloth holder is detachably attached to the receiver while holding the cloth thereon.
摘要:
A light projector has a light emitting device having a light emitting surface, an optical fiber having an incident end-face to which light emitted from the light emitting surface enters, and a lens arranged between the light emitting surface of the light emitting device and the incident end-face of the optical fiber. The light emitting device, the optical fiber and the lens are arranged on one optical axis. The optical fiber includes a core region as a region including a single core of uniform refractive index or a region collectively encompassing a plurality of cores having uniform refractive index. The lens converts diffused light emitted from the light emitting surface to diffused light that widens more moderately.

摘要:
A first light-blocking member and a second light-blocking member are adhered to each other by forming a light-transmitting layer having a light-transmitting composition serving as a base material and a light-transmitting filler different in index of refraction from this light-transmitting composition on a front surface of the first light-blocking member. A liquid light curing adhesive is applied to a front surface of the light-transmitting layer. The second light-blocking member is arranged on the front surface of the light-transmitting layer to which the liquid light curing adhesive has been applied. The liquid light curing adhesive is cured by irradiating the light-transmitting layer with light having a prescribed wavelength laterally from a side of the light-transmitting layer so as to adhere the light-transmitting layer and the second light-blocking member to each other. By adhering light-blocking members to each other, an adhesion operation may easily and quickly be performed with sufficient adhesion strength.

A transaction processing system includes a first server containing a first memory domain and configured to perform a transaction process as a current operation server; and a second sever containing a second memory domain which has a same size as the first memory domain and stores a replica of data stored in the first memory domain. The transaction processing system further includes third and fourth servers activated to have third and fourth memory domains, respectively; and a control server configured to monitor a failure of the first and second servers.
