Patent JP-H0235777-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: OKADA SHOZO
IPC: H01L29/78
Filed: 1988-07-26
Abstract: PURPOSE:To improve the operating speed of a semiconductor device by designing the device so that hot electrons injected into the boundary between an LDD region and a gate oxide film may be discharged by action of a polycrystalline silicon gate electrode in a lower layer and that diffusion of low-resistance conductor atoms to the lower polycrystalline silicon electrode is prevented by a reaction stopping layer and a barrier, metal film formed on the side walls of the gate. CONSTITUTION:An oxide film 110 is formed on an Si substrate 100. A thin Si oxide film 120 is further formed in an active region. After polycrystalline Si 130 is deposited all over the surface by the CVD, a dopant such as P or the like is diffused to convert it into a low resistor. After an Si oxide film 140 is deposited, a W film 150 and an Si oxide film 160 are deposited sequentially. Resist pattern 170 is formed so that the Si oxide film 160, the W film 150 and the Si oxide film 140 are etched by anisotropic dry etching. P ions are then implanted with a mask of the pattern 170 so that an N<-> type region 180 is provided in the Si substrate 100. After the pattern 170 is removed, a Ti nitride film 185 is formed. The Ti nitride film 185 and the polycrystalline Si film 130 are etched and As ions are implanted to form source and drain regions 100. Then, an insulating film 195 is formed, heat treated and provided with contact holes 196. Finally, aluminum electrodes 197 are formed. According to such arrangement, resistance of the gate electrode can be decreased stably with good yield and, therefore, a semiconductor device operable at higher speed can be obtained.

Title: Phenol resin laminated board and its manufacture
Inventor: OGATA MASARU
IPC: H05K1/03
Filed: 1988-07-27
Abstract: PURPOSE:To obtain a laminated board which is excellent in punching workability, moisture resistance, and electric characteristics by decreasing expansion and shrinkage especially in a thickness direction by a method wherein a paper base material into which aluminum hydroxide is mixed, is used. CONSTITUTION:For a phenol resin laminated board of a paper base material, the paper base material into which 20 to 80wt% aluminum hydroxide is mixed to be made, is used and further, flame-retardant phenol resin is used as phenol resin. Further, by treating preliminarily an aluminum hydroxide mixed paper base material with melamine resin, strength of the base material is increased and besides, affinity for the phenol resin is improved. Then, stability of operation when impregnated with phenol resin is achieved. Though an impregnation amount of melamine resin is suitably determined according to a mixing amount of aluminium hydroxide, when an amount of resin does not reach 1wt%, effect of treatment can not be expected. When it exceeds 5wt%, the paper base material becomes brittle to be liable to break when impregnated with phenol resin.

Title: Inference result displaying system
Inventor: SHIMIZU MIHO
IPC: G06F9/44
Filed: 1985-08-28
Abstract: PURPOSE:To grasp easily a whole inference process as the relation of an object, and to explain it visually by storing knowledge as an object, deducing the knowledge by an object unit, executing the inference, storing the inference process as a relation of the object, and displaying the whole process of the inference, and the result by an object unit. CONSTITUTION:For instance, it is supposed that a user pictures an image of a cheetah in his mind, and desires to infer its name by a system. First of all, since it is clear that its object is an animal, an object name of 'animal' is inputted as an argument. An inference mechanism 2 searches an object of 'animal' from an object memory device 1, and checks whether a value of its actual example (young=an object of a subordinate concept) is stored or not. In this case, two objects of 'Mammalia' and 'carnivorous animal' are stored, therefore, first of all, 'Mammalia' of the first order is fetched. An affinitive attribute of 'Mammalia' is 'animal' only, therefore, an operation for following up a parent is not executed.
