摘要:
A method of forming an electrical contact between interconnection layers located at different layer levels includes the steps of forming a contact hole in an interlayer insulating film, and forming a metallic intermediate layer on an exposed surface portion of a first conductive interconnection layer and the interlayer insulating film. Then, a portion of said metallic intermediate layer exposed through said contact hole and an oxide film formed on said surface portion of the first conductive interconnection layer are eliminated by an etching process. This process is carried out in a vacuum. After that, in the vacuum, a second conductive interconnection layer is formed in said contact hole and formed on said interlayer insulating film so that an electrical contact between said first and second conductive interconnection layers are formed.

摘要:
In a data processing apparatus, when an instruction for starting validation is provided, or when definition information is updated, data input from a data source is collected, and a process for narrowing down of the collected data is executed. In the data narrowing process, by extracting records and items as process targets according to the definition information that defines the operation of the apparatus, the number of data items used for validation is reduced. Then, the operation is validated using the narrowed data. In the operation validation process, a virtual transfer destination of output of data is provided within the apparatus, and the data is output to the virtual transfer destination, for comparison with the output data, whereby the validation of the operation is performed.

A high-dielectric-constant film including hafnium, wherein the above-mentioned high-dielectric-constant film includes deuterium at a ratio higher than the ratio of deuterium to hydrogen present in nature. In a field-effect transistor provided with the high-dielectric-constant film including hafnium, the interface state density at the interface between a silicon substrate and a gate dielectric film decreases and carrier mobility in the gate dielectric film increases. In the present invention, a high-dielectric-constant constant second dielectric film, which is a thin film including hafnium such as HfSiON or HfAlOx and including deuterium at a ratio higher than the ratio of deuterium to hydrogen present in nature, is used as the gate dielectric film of the field-effect transistor.

A fluorescent X-ray analyzing apparatus capable of being used as either a wavelength dispersive type or an energy dispersive type is provided, with which the analysis can be performed quickly and accurately. The fluorescent X-ray analyzing apparatus includes a detecting unit for detecting and analyzing fluorescent X-ray (5) emitted from at least one target area (1a) of a sample (1) to be analyzed as a result of excitation of such target area (1a) with a primary X-ray (3). The detecting unit includes a wavelength dispersive type detecting unit (6) including a spectroscope (8) and a first detector (9), and an energy dispersive type detecting unit (11) including a second detector (12) of an energy dispersive type. The angle &thgr;1 formed between a first path (81) of travel of the fluorescent X-ray from the target area (1a) towards the spectroscope (8) and a surface of the sample (1) is equal to the angle &thgr;2 formed between a second path (82) of travel of the fluorescent X-ray from the target area (1a) towards the second detector (12) of the energy dispersive type and a surface of the sample (1), but the second path (82) is shorter than the first path (81).

摘要:
A ceramic article such as a sanitary pottery ware is produced by slip casting using a porous composite mold. A green ceramic body of a part such as a trap of sanitary ware is separately formed in advance by, for example, slip casting. The green ceramic body is placed in the mold cavity of the porous composite mold. Then, a slip as the material of the main part of the sanitary ware is supplied into the mold cavity to form deposit integral with the green ceramic body, whereby an integral sanitary ware is obtained by slip casting.
