摘要:
A surface acoustic wave device in the present invention is provided with a piezoelectric substrate, a supporting substrate being jointed to the piezoelectric substrate and including a material different in expansion coefficient from the piezoelectric substrate and an interdigital electrode for exciting a surface acoustic wave, the electrode being arranged on the surface of the piezoelectric substrate. Either the interdigital electrode or the piezoelectric substrate is configured so that the interdigital electrode is 40% or more to 70% or less as long as the piezoelectric substrate in the direction to which a surface acoustic wave propagates.

摘要:
An electronic device of a chip size having improved airtightness is designed to be formed by a reduced number of process steps. An electronic component including a chip having a functional surface and electrodes at least on one side and a substrate having a portion which can be connected to the electrodes of the chip is designed as such an electronic device. In the electronic component, electroconductive glass or an intermetallic compound is used for connection portions to establish electrical connections between the chip and the substrate and to simultaneously seal the device surface on the chip.

A screen transition diagram creator that creates a screen transition diagram illustrating complicated transition relations in an easy-to-understand manner, including: a screen transition diagram editor providing the screen transition diagram in which transition relations among plural screens are illustrated by plural screen nodes and arrows between the screen nodes; a screen transition pattern applying unit applying a predetermined screen transition pattern to a target screen node group that includes at least part of the screen nodes illustrated in the screen transition diagram to provide a pattern-applied screen node group; and a screen transition structure diagram creator creating a screen transition structure diagram by abridgement processing on the pattern-applied screen node group according to a display layout corresponding to the screen transition pattern. In the abridgement processing, arrows are deleted and an icon that simplistically illustrates a transition pattern between the screen nodes displayed in the display layout is added.

摘要:
An electronic device, in which terminals of a semiconductor integrated circuit chip and terminals of a circuit substrate are mounted with solder so as to face one another. The electronic device includes a first resin, which is disposed between the circuit substrate and a terminal formation face of the semiconductor integrated circuit chip and a second resin, which is disposed at the outer perimeter of the semiconductor integrated circuit chip or is disposed laterally thereon. The modulus of elasticity of the second resin is smaller than the modulus of elasticity of the first resin, the modulus of elasticity of the second resin is at least 0.5 GPa but not more than 28 GPa at room temperature.

Dispersion of a load may be kept within a predetermined allowance even when a plurality of probes in a large area are pressed in batch by pressing the probes provided in a membrane against a wafer by applying a pressure load to a plurality of places on a plane of the pressure members on the side opposite the wafer in a probe test step, burn-in test step which represent typical semiconductor device manufacturing steps. It is then possible to provide semiconductor devices and a manufacturing method thereof which enhance the reliability and productivity of the semiconductor devices by probing a large number of integrated circuits or a large size integrated circuit at the same time.
