摘要: The invention provides an information processing apparatus and method and a providing medium by which editing of routing can be performed rapidly and readily. When a node which has no DEF name applied thereto is dropped into a route window, a routing editing tool provides a DEF name to the dropped node. When a node displayed in the route window or a scene graph window is dragged by a mouse and dropped to another node displayed in the scene graph window or the route window, the routing editing tool displays route candidates which can be set between the two nodes. When a user selects one of the displayed route candidates, the routing editing tool sets the selected route candidate as a route between the nodes.

摘要: In a nitride compound semiconductor laser including an active layer sandwiched by semiconductor layers of different conduction types on a sapphire substrate, layers of polyimide for current blocking and light confinement are formed on side surfaces of a mesa-type current confining structure with and under the p-side electrode. The laser ensures efficient, uniform carrier injection into the active layer, suppresses higher-order modes other than the fundamental transverse mode, and thereby promises a high reliability ensuring continuous pulsation under a low threshold current and a low operation voltage with low noise characteristics.

摘要: Cleaning apparatus provide for the cleaning of a workpiece by first immersing the workpiece in a cleaning tank having a cleaning liquid therein for a predetermined period of time, removing the workpiece from the cleaning tank, moving the workpiece through air for a pre-selected period of time, and supplying the workpiece to a drying device which then dries the workpiece. As the workpiece is moved through the air, the workpiece may be vibrated, moved at an incline then a decline, and/or have air blasted at it, so that any liquid, e.g. rinsing solution, remaining thereon is caused to fall off, such occurring prior to the drying of the workpiece by the drying device.

摘要: After p-type gallium nitride compound semiconductor layers, to which p-type impurity is added, are formed by virtue of chemical vapor deposition, the p-type gallium nitride compound semiconductor layers are thermally annealed at more than 400.degree. C. or more than 700.degree. C. while supplying a flow of an inert gas in parallel to a substrate surface at a predetermined flow rate or more. Otherwise, the p-type gallium nitride compound semiconductor layers are thermally annealed at more than 400.degree. C. or more than 700.degree. C. in an inert gas atmosphere having a predetermined pressure or more. According to the annealing process, the p-type impurity can be more effectively activated, so that p-type gallium nitride compound semiconductor layers which have fewer crystal defects, etc. and have lower resistivity can be formed.

摘要: A semiconductor light emitting device has a double heterostructure. The device is composed of an active layer and clad layers that sandwich the active layer. At least one of the clad layers has a multilayer structure having at least two element layers. The Al mole fraction of an element layer, which is proximal to the active layer, of the multilayer structure is smaller than that of the other element layer thereof distal from the active layer. This arrangement improves the crystal quality of an interface between the active layer and the clad layer of multilayer structure and effectively confines carriers in the active layer.
