摘要:
A hydrophobic compound having at least one each of hydrophobic group (an alkyl group having 1 to 6 carbon atoms or a —C6H5 group) and polymerizable group (a hydrogen atom, a hydroxyl group or a halogen atom) is allowed to undergo a gas-phase polymerization reaction, under reduced pressure (of not more than 30 kPa), in the presence of a raw porous silica film and to thus form a modified porous silica film wherein a hydrophobic polymer thin film is formed on the inner walls of holes present in the raw porous silica film. The resulting porous silica film has a low relative dielectric constant and a low refractive index and the silica film is likewise improved in the mechanical strength and hydrophobicity. A semiconductor device is produced using the porous silica film.

摘要:
The coating liquid for forming porous silica according to the present invention is characterized by preferably containing a partial hydrolysis-condensation product of an alkoxysilane compound, a surfactant and an organic ampholyte, and by having a metal content of not more than 50 ppb. Conventional coating liquids for forming porous silica have such a problem that porous silica films formed therefrom may have poor regularity in micropore alignment when the shelf life of the coating liquids are long. On the contrary, the coating liquid for forming porous silica of the present invention is excellent in self-life stability. Namely, the quality of porous silica formed therefrom is hardly affected by the length of self-life period of the coating liquid. Consequently, the coating liquid is expected to contribute to the stable preparation of porous silica films which cause no shift in capacitance or voltage when exposed to an electric field, have regularly aligned uniform micropores, and are preferably used as an optically functional material or an electronically functional material.
摘要:
A quench solidification method, wherein a steel cast strip having a mean grain size 50 μm or more is prepared and then the steel cast strip is rolled to produce a non-oriented electrical steel sheet having high magnetic flux density in both L and C directions. However the magnetic flux density reduces when the cold reduction rate exceeds 70%. To avoid this problem the non-oriented electrical steel sheet is manufactured with a ratio of at least 4 of the integrated intensity of the {100} plane for a given sample of steel to the integrated intensity of {100} plane for a “random” sample in which crystal grains have random orientations; and a cold reduction rate of the cold-rolling is between 70% and 85%. The superheating degree of the molten steel can be 70° C. or more.

The matting agent comprises one or at least two types of organic or/and inorganic porous fine particles. The porous fine particles have a mean particle diameter in the range of 0.5 to 20 μm and a specific surface area in the range of 1 to 1000 m2/g. The release sheet is produced by using the composition.
摘要:
Impurity ions contained in a semiconductor layer are diffused downwardly from a gate electrode by irradiating laser light from the back surface of a transparent substrate after source-drain regions are formed. Thus, a GOLD structure is formed. Consequently, the GOLD structure is formed by performing a smaller number of processes. Also, variation in characteristics can be suppressed by preventing occurrence of asymmetry between left and right LDD regions.
