A repairer coupled to a plurality of these inspectors collects the stored files and merges the files and executes a repair process as a batch at one time with reference to the merged files. A file server is coupled to the inspectors through a network, and stores the files of the inspectors and provides the file when the repairer retrieves the files. An automatic transfer device controlled by a host automatically transfers the panels between the inspectors and between the inspector and the repairer, and an automatic transfer device controller coupled to the host receives commands from the host and controls transfers of the automatic transfer device.

    摘要: An antenna system measurer (110a, 110b, 110c) for a repeater and a base station (10) measures powers of a progressive wave and a reflected wave of a transmit/receive antenna, and transmits measured results to a monitoring server (200) in a radio data format such as an SMS message. The monitoring server (200) receives the radio data, identifies a repeater and a base station from sender information of the radio data, and calculates a VSWR based on the measured values. The VSWR is modified based on characteristics of the base station such as length and substance of feeders from a base station identifier corresponding to the sender information. According to the present invention, the remote antenna system is monitored in real-time without visits or installation fees, and a plurality of repeaters and base stations is managed in a combined manner.

    摘要: A method of forming a tungsten plug in a semiconductor device includes forming a contact hole in an insulating layer, forming a contiguous titanium layer in the contact hole and on the insulating layer, forming a titanium nitride layer on the titanium layer. forming a thin tungsten layer of about 50 angstroms or less on the titanium nitride layer by CVD (chemical vapor deposition), annealing the structure once the thin tungsten layer has been formed, and depositing additional tungsten by CVD to completely fill the contact hole. The titanium nitride layer can be formed by a discrete CVD process or as a result of the annealing process. Forming a thin tungsten layer by CVD before the contact hole is completely filled in with tungsten is used to stabilize the titanium layer. For instance, a small amount of fluorine from the source gas of the thin tungsten layer diffuses into the titanium layer. Annealing the structure then diffuses the fluorine uniformly throughout the titanium layer to the point where additional fluorine from the subsequent CVD process of depositing tungsten can not diffuse into the titanium layer This, in turn, prevents a reaction at the titanium layer from taking place at the time the contact hole is filled in completely with tungsten. Accordingly, the titanium nitride layer remains adhered to the insulating layer.
