    摘要： Optocoupler devices and methods for making and using such devices are described. The optocoupler devices contain a light emitting component (a light emitting diode [LED]) and a light receiving component (a phototransistor [PT]) device that are embedded within the substrate, rather than being attached to the surface of the pre-molded substrate. Such a configuration eliminates the bond wires that are often used when the LED and PT are attached on the substrate, improves the electrical performance, and allows the final optocoupler package to be made smaller and thinner. Other embodiments are described.

    摘要： A method for relaying a route request RREQ message by an intermediate node which is connected with at least one node using a tree topology in a mobile communication system including a destination node and a source node which sends the RREQ message to the destination node via at least one intermediate node, to thus establish an optimal route for communications. The RREQ message is received along the route other than the tree route, and the first information is updated using its information. The intermediate node relays to a next intermediate node the RREQ message containing the updated first information.

    摘要： Disclosed are semiconductor die packages constructed from modules of embedded semiconductor dice and electrical components. In one embodiment, a semiconductor die package comprises a first module and a second module attached to the first module. One or more semiconductor dice are embedded in the first module, and one or more electrical components, such as surface-mounted components, are embedded in the second module. The first module may be formed by a lamination process, and the second module may be formed by a lamination process or a molding process. Patterned metal layers and vias provide electrical interconnections to the package and among the die and components of the package. The second module may be attached to the first module by coupling interconnect lands of separately manufactured modules to one another, or may be directly attached by lamination or molding.
