The present invention relates to an RFID tag performing exchange of information with an external device without contact, and is to improve the resistance to bending while avoiding an increase in the thickness of the RFID tag. A circuit chip is bonded to a base portion of a base with a thermosetting adhesive. The base is folded, and an ultraviolet curing adhesive is applied on the circuit chip. The fold-back portions of the base are folded back onto the circuit chip, to which portions ultraviolet light is irradiated, as a result, both of the surfaces of the circuit chip are bonded to the base with the adhesives.

The present invention provides a radio frequency identification (RFID) tag which exchanges information with an external device in a noncontact manner, in which a paste is used as a material for an antenna, and which is designed to avoid the problem due to swelling of the paste caused by a pressing force from bumps of an IC chip. A paste escape recess is provided in which part of the paste provided to form the antenna is caused to flow therein by the pressure received from the bumps when the IC chip with the bumps is connected to the antenna.

A fabrication method of a semiconductor device is disclosed. The method includes the following steps. First, a given number of projection electrodes are formed on each of a given number of semiconductor chips, and a thermosetting insulating adhesive is applied to areas of mounting parts where the semiconductor chips are to be mounted on a substrate. Second, the thermosetting insulating adhesive on the substrate is heated with a half-thermosetting temperature. Third, the semiconductor chips are aligned to the mounting parts of the substrate and a first fixing of the semiconductor chips is performed with a first pressure. Fourth, the substrate, on which the semiconductor chips are fixed, is heated with a thermosetting temperature of the thermosetting insulating adhesive, and a second fixing of the semiconductor chips is performed with a second pressure.

There is provided a method of assembling a carriage assembly that can crimp suspensions to carriage arms by applying ultrasonic vibration to a crimping tool without causing deformation of the suspensions and the like. The method of assembling a carriage assembly aligns attachment holes provided in front ends of carriage arms and crimping portions provided on suspensions to set the suspensions on the carriage arms and then presses a metal ball through crimping holes provided in the crimping portions while applying ultrasonic vibration to a crimping tool to crimp the suspensions to the carriage arms. The suspensions are crimped to the carriage arms by detecting stress that acts on the crimping tool when the metal ball is pressed in by the crimping tool and controlling the amplitude of the ultrasonic vibration applied to the crimping tool so as to increase and decrease in accordance with the magnitude of the stress.

A method of mounting a semiconductor device having bumps on a board having pads so that each of the bumps is joined to a corresponding one of the pads is provided. Adhesive to be hardened by heat is provided between the semiconductor device and the board. The method includes the steps of pressing the bumps of the semiconductor device on the pads of the board, and heating a portion in which each of the bumps and a corresponding one of the pads are in contact with each other. A pressure of the bumps to the pads reaches a predetermined value before a temperature of the adhesive to which heat is supplied in the above step reaches a temperature at which the adhesive is hardened.

A solar cell has a passivation film formed on a crystalline silicon substrate that has at least a p-n junction, and an electrode formed by printing and heat-treating a conductive paste. The solar cell has a first electrode comprising an extraction electrode, which extracts photogenerated carriers from the silicon substrate, formed so as to contact the silicon substrate and a second collector electrode, which collects the carriers collected at the extraction electrode, formed so as to contact the first electrode. Other than the point of contact between the first electrode and the second electrode, at least, the second electrode contacts the silicon substrate only partially or not at all. By leaving the passivation film between the collector electrode and the silicon, either completely or partially, the solar cell reduces charge losses at electrode/silicon interfaces, improves the short-circuit current and open voltage, and yields improved characteristics.

A sheet punching apparatus capable of improving the accuracy of movement distance of a movable member and maintaining the durability of a drive unit of the apparatus. A sheet post-processing apparatus controller computes a time period corresponding to an amount of overrun of a slider at the time of stopping the slider in an initial operation. In a punching operation, the sheet post-processing apparatus controller starts a punch motor at a timing earlier by the computed time period corresponding to the amount of overrun than a stop timing of a conveyance motor.

A semiconductor substrate having an electrode formed thereon, the electrode including at least silver and glass frit, the electrode including: a multi-layered structure with a first electrode layer joined directly to the semiconductor substrate, and an upper electrode layer formed of at least one layer and disposed on the first electrode layer. The upper electrode layer is formed by firing a conductive paste having a total silver content of 75 wt % or more and 95 wt % or less, the content of silver particles having an average particle diameter of 4 μm or greater and 8 μm or smaller with respect to the total silver content in the upper electrode layer being higher than that in the first electrode layer.

A folding line is pressed using both a first and second pressing members of press roller pairs. Further, positions of the first and second pressing members are shifted from each other. When the number of the sheets included in a booklet is a predetermined number or less, the folding line is pressed by only the first pressing member. When the number of the sheets is more than the predetermined number, the folding line is pressed by both the first and second pressing members.
