摘要： When measuring an edge region, a photo detector with an angle not influenced by the diffracted light, the diffracted light causing noise, is selected to thereby allow for inspection that minimizes the sensitivity reduction. This allows for the management of foreign matters in the outer peripheral portion, which conventionally could not be measured, and this also eliminates the oversight of critical defects on the wafer, thus leading to reduction of failures of IC.

摘要： The present invention realizes a nanotube probe with high durability that can be manufactured in short time with less impurities adhered to the holder sustaining the nanotube. The nanotube probe according to this invention is constructed by fastening a nanotube 8 on the protruded portion 4 of a cantilever by way of at least two partial coating films 12a and 12b. One or more additional partial coating films may be formed in the intermediate area between these two partial coating films. Each partial coating film is formed by irradiating electron beam 10 on the position where the nanotube 8 is in contact with the protruded portion 4 of the cantilever. The partial coating films are separated not to overlap each other. By minimizing the size of partial coating film as well as by narrowing down the beam diameter, coating time may be further shortened. With the beam diameter narrowed down, excessive deposit of impurities can be put under control.

摘要： A carbocyclic or heterocyclic compound, ammonia and an oxygen-containing gas are subjected to fluid catalytic reaction in vapor phase in the presence of a catalyst containing alkali metal to produce an aromatic or heterocyclic nitrile. The use of the catalyst containing a specific amount of alkali metal enables the stable production of the aromatic or heterocyclic nitrile in high yields with little change with time even when water is present in the reaction system. The use of the catalyst containing the alkali metal also enables the recycle and reuse of unreacted ammonia which is usually accompanied by water, thereby reducing production costs.

摘要： A detector is provided to optically monitor the outer periphery of a wafer rotated by rotation of a rotary stage, so as to detect how much the center of the wafer placed on the rotary inspection stage is offset from the rotational center of the rotary stage as well as an angular position, on the stage, of a V-shaped notch formed in the wafer. From the detected eccentricity of the wafer, it is determined whether a precise positioning operation, using at least three positioning pins, to locate the center of the wafer at the rotational center of the rotary stage should be performed or not. When the detected eccentricity is so great as to necessitate the precise positioning operation, one of the positioning pins is caused to fit into the V-shaped notch of the wafer on the basis of the detected angular position of the notch and then the precise positioning of the wafer is performed using the other two positioning pins. In this manner, the wafer can be properly positioned so that the center of the wafer lies exactly at the rotational center of the rotary stage, using the at least three positioning pins.

摘要： In a multilayer ceramic capacitor comprising internal electrodes of an Ag-Pd alloy, by incorporating 0.05 to 0.7%, by weight of Ag into a ceramic dielectric layer, the equivalent series resistance can be reduced and the capacitance can be increased. Incorporation of Ag in the dielectric layer can be accomplished by adding Ag.sub.2 O into a green sheet of the dielectric material in advance or by firing a green sheet of the dielectric material in a powder containing Ag.sub.2 O.
