A wiring board includes a core substrate having a structure including an insulating base material and a large number of filamentous conductors densely provided in the insulating base material and piercing the insulating base material in a thickness direction thereof. Pads made of portions of wiring layers are oppositely disposed on both surfaces of the core substrate and electrically connected to opposite ends of a plurality of filamentous conductors in such a manner that the pads share the filamentous conductors. A wiring connection between one surface side and the other surface side of the core substrate is made through the pads. The insulating base material is made of an inorganic dielectric. Pads made of portions of the wiring layers are disposed on both surfaces of the core substrate and electrically connected only to corresponding one end sides of different groups each formed of a plurality of filamentous conductors.

There is provided a method of manufacturing a conductive film. The method includes: (a) providing an anodized layer having a plurality of through holes extending therethrough in its thickness direction; (b) forming a plurality of linear conductors by filling each of the through holes with a conductive material; (c) forming protection layers on both surfaces of the anodized layer; (d) removing the anodized layer to form a plurality of gaps between the linear conductors; (e) forming an organic insulation layer between the protection layers to fill the gaps with the organic insulation layer; and (f) removing the protection layers.

A computer-readable non-transitory recording medium storing therein an information managing program causing a computer to execute extracting from among events that have occurred at objects under management and having dependence relations, combinations of a first event that has occurred at a source-of-dependence object and a second event that has occurred at a dependent object dependent on the source-of-dependence object; judging for each extracted combination, whether a dependence relation exists between the first event and the second event, by using the difference between the time of occurrence of the first event and that of the second event; determining from among the events and based on a judgment result obtained at the judging, an event that has occurred at an object that is a source-of-dependence object but not a dependent object, to be an event to be stored; and storing to a database, information related to the event to be stored.

A substrate processing apparatus includes a holder configured to hold a substrate and carry the substrate into a process chamber, a waiting station located outside the process chamber in which the holder waits prior to carrying the substrate into the process chamber, a circulation path configured to circulate a gas throughout the waiting station, and an exhaust path formed in the circulation path and configured to exhaust the gas from the waiting station.
