摘要:
An information processing apparatus capable of being opened and closed includes storage means, display means, and taken image display control means. The storage means stores a taken image therein. The display means has a display screen provided in a surface which is located inside when the information processing apparatus is closed and which is located outside when the information processing apparatus is opened. The taken image display control means displays a taken image on the display screen, and changes a taken image to be displayed between before and after closing and opening the information processing apparatus when the information processing apparatus is closed and opened again.

An icon line is displayed on a screen. A display order for the icon line can be changed by using a switch input unit enabling a direction input. When an input in a first direction is made, objects are scrolled so as to sequentially display each object at a specific position or the objects are scrolled across the specific position. When an input in the second direction is made, an object positioned at the specific position is saved at a saving position or an object positioned at the saving position is positioned at the specific position. Thus, a user is allowed to easily change the display order in which a plurality of objects are displayed on a screen.

An electrically conductive GaAs crystal has an atomic concentration of Si more than 1×1017 cm−3, wherein density of precipitates having sizes of at least 30 nm contained in the crystal is at most 400 cm−2. In this case, it is preferable that the conductive GaAs crystal has a dislocation density of at most 2×10−2 cm2 or at least 1×10−3 cm2.

摘要:
A continuous copper electroplating method wherein copper is continuously plated on a workpiece to be placed in a plating vessel accommodating a copper sulfate plating bath containing organic additives by use of a soluble or insoluble anode and a workpiece as a cathode, the method including overflowing the plating bath from the plating vessel in an overflow vessel under which the plating bath in the overflow vessel is returned to the plating vessel, providing an oxidative decomposition vessel, and returning a plating bath from the oxidative decomposition vessel through the overflow vessel to the plating vessel to circulate the plating bath between the plating vessel and oxidative decomposition vessel, and metallic copper is immersed in the plating bath in the oxidative decomposition vessel and exposed to air bubbling, so that decomposed/degenerated organic products formed by decomposition or degeneration produced during the copper electroplating can be oxidatively decomposed.
摘要:
A copper electroplating bath useful in filling non-through holes formed on a substrate which contains a water-soluble copper salt, sulfuric acid, and chloride ions and further contains a brightener, a carrier, and a leveler as additives, wherein the leveler contains at least one water-soluble polymer containing quaternary nitrogen, tertiary nitrogen, or both which are cationizable in a solution. In the copper electroplating bath, the filling power for non-through holes formed on a substrate can be easily controlled so as to fit to the size of the holes only by changing the quaternary nitrogen to tertiary nitrogen ratio of the water-soluble polymer to be used as the leveler, which enables copper electroplating of non-through holes of various sizes with a good fit to the sizes.

摘要:
Disclosed is a method for a repeated electroplating of a workpiece to be plated as a cathode by using an insoluble anode in a plating vessel accommodating a copper sulfate plating bath, wherein a copper dissolution vessel different from the plating vessel is provided, the plating bath is transferred to the copper dissolution vessel and is returned from the copper dissolution vessel to the plating vessel for circulating the plating bath between the plating vessel and the copper dissolution vessel, copper ion supplying salt is charged into the copper dissolution vessel and dissolved in the plating bath so that copper ions consumed by the plating can be replenished, and the workpiece to be plated is continuously electroplated, characterized in that the plating bath is permitted to transfer between the anode side and the cathode side, and the plating bath is returned to vicinity of the anode in the return of the plating bath from the copper dissolution vessel to the plating vessel. Plating performance impairing components, which are produced when the copper ion supplying salt is dissolved in the plating bath for replenishing the copper ions, are oxidized and decomposed, whereby defective plating due to the presence of the plating performance impairing components can be prevented.
