Disclosed herein are a via hole having a fine hole land with which the density of circuit patterns can be increased and a method for forming the same. The method comprises: step 1 of forming a via hole in a copper clad laminate, coating an etching resist over the copper clad laminate, and forming a circuit pattern on the copper foil of the copper clad laminate; step 2 of forming a seed layer, coating a photoresist, and exposing an inner wall of the via hole; and step 3 of forming a plated layer on the inner wall of the via hole and removing the photoresist and the seed layer.

Disclosed is a printed circuit board (PCB) having a thin core layer and a method of fabricating the same. In the method, a substrate, where a copper foil is formed on a release film and a prepreg, is employed as a base substrate and a core insulating layer is removed after the fabrication of the PCB, thereby reducing the thickness of the final product.

Method and apparatuses are disclosed to substantially compensate for various unwanted interferences and/or distortions within a communications receiver. Each of these apparatuses and methods estimate the various unwanted interferences and/or distortions within the communications receiver. Each of these apparatuses and methods remove the estimates of the various unwanted interferences and/or distortions within the communications receiver from one or more communications signals within the communications receiver to substantially compensate for the various unwanted interferences and/or distortions.

A high quality white light emitting device suitable for miniaturization. The white light emitting device according to the present invention includes a substrate and a light emitting structure composed of an n-semiconductor layer, an active layer and a p-semiconductor layer. The light emission structure emits first emission light. The white light emitting device also includes a wavelength-converting film for absorbing and converting the first emission light to second emission light of another wavelength. The wavelength-converting film is made of europium-silicate.

Provided are methods for automatically selecting a cluster header to dynamically configure a wireless sensor network, and encoding and sending a packet between nodes in a wireless sensor network to secure communication. The method includes: broadcasting, at each normal node, cluster header selecting information including capability information of the normal node, identification information of a cluster including the normal node, and identification information of the normal node, to neighboring nodes; and judging, at each normal node, if the normal node will be selected as a cluster header using the cluster header selecting information received from at least one neighboring node.
摘要:
A method of manufacturing a flash memory cell. The method includes controlling a wall sacrificial oxidization process, a wall oxidization process and a cleaning process of a trench insulating film that are performed before/after a process of forming the trench insulating film for burying a trench to etch the trench insulating film to a desired space. Therefore, it is possible to secure the coupling ratio of a floating gate by maximum and implement a device of a smaller size.
摘要:
A method and apparatus for providing a point-to-multipoint service to a mobile terminal that moves from an area controlled by a first radio network controller (RNC) to an area controlled by a second radio network controller is provided. Information regarding a transmission mode status of the second RNC is utilized by the first RNC to determine if it is necessary to transmit MBMS data to the second RNC. MBMS data is transmitted from the first RNC to the second RNC only if the transmission status of the second RNC is point-to-point, thereby preventing unnecessary data transmission between the first RNC and second RNC and the enhancing the efficiency of the radio resources between the second RNC and the mobile terminal.
