Abstract: The invention relates to pigments consisting of substantially spherical particles with a mean particle diameter of less than 10 mu m, on the basis of an oxidic or silicate substrate material with noble metal distributed extremely finely on and/or in the particles. Preferred pigments are purple-coloured and are based on an oxide from the series SiO2, SnO2, and ZrO2 and gold as noble metal. The pigments are suitable for the production of ceramic decors and for the dyeing of plastics, synthetic films and fibres as well as lacquers. Exceptional application properties are obtained by virtue of the spherical shape. The pigments are obtainable by a spray-pyrolysis process in which an aerosol consisting of a solution of at least one noble metal compound and an oxide- or silicate-forming precursor is subjected to pyrolysis; the pigment is separated from the pyrolysis gas.

Granted: 2001-10-21
Abstract: The present invention relates to a kind of manufacturing method of capacitor. The first conductive layer is formed on the provided inter-layer dielectric layer and is followed by covering the first conductive layer with a dielectric layer. Then, rapid thermal annealing process is performed, or plasma process is conducted onto the dielectric layer so as to further increase the dielectric layer quality. After that, photolithography process and etching process are conducted to define the first conductive layer for use as the bottom electrode of the capacitor; and additionally, the inter-layer dielectric layer outside the bottom electrode region is exposed. Then, the conventionally known interconnects process is conducted. For example, an adhesion layer and the second conductive layer are sequentially formed on the dielectric layer and the exposed inter-layer dielectric layer. The second conductive layer is defined such that the second conductive layer on part of the adhesion layer, which is on the dielectric layer, is used as the upper electrode of capacitor, and the second conductive layer on top of the inter-layer dielectric layer is used as interconnects.

Filed: 1999-02-05
Granted: 2001-07-01
Abstract: The present invention provides an optical head which can eliminate the decentering following the compact disk; and, while the light spot on the recording film crosses a track on a storage film surface can eliminate the interference generated from the focus deviation signal; then, can eliminate the offset of the tracking error signal following the movement of the lens.

Therefore, the invention can compensate the situation of focal point shift error signals between the main spots and sub-spots based on appropriate gain ratio and also can eliminate the interference generated from the focal point shift error signals; and, according to appropriate gain ratio, can eliminate the situation for using push-pull to track the error signal by the main spots and the sub-spots so as to eliminate the deviation.
