Structures, methods, and systems for assessing bonding of electrodes in FCB packaging are disclosed. In one embodiment, a method comprises mounting a semiconductor chip with a plurality of first electrodes of a first shape to a mounted portion with a second electrode of a second shape, wherein the second shape is different from the first shape, bonding a respective one of the plurality of first electrodes and the second electrode using a first solder bump, generating an X-ray image of the first solder bump, and determining an acceptability of the bonding of the respective one of the plurality of first electrodes and the second electrode based on the X-ray image of the first solder bump.

A carrier for a stacked-type semiconductor device includes an accommodating section for accommodating stacked semiconductor devices, guide portions guiding the stacked semiconductor devices, and grooves through which a fluid may flow to the accommodating section and to sides of the stacked semiconductor devices. These grooves facilitate the flow of gas or liquid on the sides of the accommodating sections, and it is thus expected that the flow of hot wind during the reflow process and cleaning liquid during the cleaning process can be facilitated. This improves the production yield and the cleaning effects. Holes for connecting the accommodating section to the outside may be provided at corners of the accommodating section. Gas may be guided from the lower side of the accommodating section, so that heat can be efficiently applied to the semiconductor devices and bonding failures therebetween can be reduced. Further, grooves connecting adjacent holes may be provided for accommodating sections adjacent to each other.

In the sliding portable telephone of the present invention, on the surface of the base housing, a photoconductive member is placed along a boundary line between a first surface region which is exposed when the slide housing is placed at the open position and a second surface region which is covered by the slide housing, a light emitting element for emitting light toward an end part of the photoconductive member on the second surface region side is arranged inside the base housing. The slide housing is provided with a reflecting plate reflecting light which has passed through the photoconductive member toward an end part of the photoconductive member on the first surface region side at a position opposed to a surface of the photoconductive member when the slide housing is placed at the open position.

A method for manufacturing a semiconductor device is disclosed. As a part of the method, one surface of a substrate is molded with resin where the substrate and the resin are heated in a first heating process and maintained in a flat condition. The substrate and the resin are returned to room temperature while being maintained in the flat condition after the first heating process. The resin is cut after the substrate and the resin are returned to room temperature from a surface of the resin that is opposite the surface of the resin where the substrate contacts the resin. The substrate is left intact when the resin is cut. Thereafter, the substrate is separated.

A carrier structure for fabricating a stacked-type semiconductor device includes: a lower carrier that has laminated thin plates and has first openings for mounting first semiconductor packages thereon; and an upper carrier having second openings for mounting second semiconductor packages on the first semiconductor packages. The lower carrier composed of the laminated thin plates realizes an even plate thickness and reduces warps because stress is distributed to the thin plates. This results in an improved production yield. A pattern of the openings in the thin plates of the lower carrier may be formed by etching or electric discharging. The openings thus formed have reduced warps and burrs.

This invention makes it possible to perform analysis for estimating the characteristics of a population using sample data. By obtaining sample data, embedding genetic (statistical) knowledge in a first and second state variable that have duality, and having the first and second state variables converge to the original value, the characteristics of the population of the sample data are estimated, and the estimated results of the characteristics of the population are output. By doing so, it is possible to perform analysis for estimating characteristics of a population using sample data.
