摘要:
A method of forming an interlayer film on a substrate with a plurality of patterns formed thereon wherein the interlayer film is deposited on the substrate by a process comprising a plurality of steps in each of which a portion of the film is deposited so as to have different fluidity with the same source material. In the first aspect of the method, a portion of the interlayer film is at first deposited so as to have relatively reduced fluidity, so that the film is formed with an almost uniform thickness regardless of any pattern width on the substrate. After this, the rest portion of the film is deposited so that it has relatively increased fluidity so as to fill up the trough between the patterns. In the second aspect of the method, an undercoating film is formed in advance which is then treated to be hydrophobic so that a portion of the interlayer film deposited thereon reduces its fluidity, by which the portion is uniformly deposited regardless of any pattern width. Then, the rest portion of the film is deposited over the above portion of the film with relatively increased fluidity.

A method and an apparatus for fabricating a thin film semiconductor device are disclosed. An a-Si:H thin film produced on a wafer is melting-recrystallized by irradiating a laser beam to it in a laser annealing chamber to produce a polycrystalline Si thin film. The wafer is then transported to a CVD chamber without exposing it to the outside air. A gate insulating film is produced on a clean surface of the polycrystalline Si thin film in the CVD chamber. In another case, an a-Si:H thin film is melting-recrystallized in the laser annealing chamber to produce a polycrystalline Si thin film and then the wafer is transported to a hydrogenating chamber without exposing it to the outside air. Thereafter the polycrystalline Si thin film is plasma hydrogenated in the hydrogenating chamber. The method and apparatus can fabricate thin film semiconductor devices having a high performance and a high reliability with a good uniformity by making a clean and high quality semiconductor/insulator interface or by hydrogenating a semiconductor thin film without changes in electrical conductivity.

Disclosed is a communication system which accommodates at least one central office network line and a plurality of extensions, and which is adapted to control line connection between the central office network line and the plurality of extensions. When a call from the central office network line is detected, it is determined in response to the call whether a control signal characteristic of data communication, such as a CST signal, is being sent by the other party's device. If such a control signal is being sent, a line to which a data processor is connected is selected and connected to the calling line. This makes it possible to connect an information processor and a telephone to a common central office network line, and to connect a call answered by another telephone to a desired information processor rapidly through a simple operation. Accordingly, it is unnecessary to assign a special-purpose central office network line to an information processor. When the information processor is not in use, therefore, another telephone may employ the same line. This improves the efficiency of line utilization.
摘要:
In fabricating bonded substrate structures having a device-housing space therein, microstructures in the bonded substrates are prevented from being broken or damaged, and the yield of the bonded substrate structures fabricated is increased. A through-groove capable of connecting the device-housing space to the outside is formed in the bonded surface of one substrate. Thus configured, the atmosphere inside the device-housing space is kept the same as the outside atmosphere while openings that reach the device-housing space are formed through the bonded substrate structure by etching the structure, and the device-housing space is prevented from being subjected to any rapid pressure change in the process of forming the openings. The depth of the through-groove may be the same as that of the recess for the device-housing space. Thus configured, the through-groove may be formed in one and the same etching treatment for forming the device-housing space. The through-groove may be partly sealed with a Pb bump or the like, and the atmosphere inside the device-housing space can be insulated from the outside atmosphere in any stage of processing the bonded substrate structure.

Disclosed is a solid activated carbon and a process for manufacturing the solid activated carbon which is particularly suitable for electrode materials used in an electric double layer capacitor and various batteries. The use of the solid activated carbon makes it possible to prepare an activated carbon substrate having high mechanical strength and practical capacitance while the content of activated carbon is high. The solid activated carbon comprises an activated carbon powder and/or an activated carbon fiber, a carburized substance of a PVA or a resin derived from PVA, and a PVA or a resin derived from PVA. The process for manufacturing the solid activated carbon comprises, molding a molding material consisting of an activated carbon powder and/or an activated carbon fiber, a PVA or a resin derived from PVA or a mixture of a PVA or a resin derived from PVA and a mesophase using a known molding method, aging the molded compact in air and heat-treating the aged compact in a non-oxidizing atmosphere.
