摘要: A metal oxide ceramic composite powder has crystals of a reacted and precipitated metal oxide distributed on fine particles of a ceramic material. The metal oxide is derived from an aqueous solution of metal chloride, which in the presence of a magnetic field, forms a complex ion solution. The complex ion may comprise a proportional blend of metallic and semi-metallic elements to produce specific properties. The complex ion is reacted and precipitated with an alkaline material to deposit a high purity metal oxide on the ceramic material. Each ceramic particle thus has a uniform coating of a high purity metal oxide deposited thereon.

摘要: A SOI substrate includes a SiO2 film (230) having a center located at the depth of the damage peak where the crystal damage is maximum after the Si substrate (10) is ion-implanted with oxygen ions. Even if a crystal defect (240) remains at the depth of the density peak where the density is maximum, the crystal defect does not effect the device operation because it is outside the active layer. By using a low-dose SIMOX process, a lower-cost SOI substrate can be obtained wherein crystal defects formed in the active layer are reduced.

摘要: There is provided a method of fabricating a silicon-on-insulator substrate, including the steps of (a) forming a silicon substrate at a surface thereof with an oxygen-containing region containing oxygen at such a concentration that oxygen is not precipitated in the oxygen-containing region in later mentioned heat treatment, (b) forming a silicon oxide film at a surface of the silicon substrate, (c) implanting hydrogen ions into the silicon substrate through the silicon oxide film, (d) overlapping the silicon substrate and a support substrate each other so that the silicon oxide film makes contact with the support substrate, and (e) applying heat treatment to the thus overlapped silicon substrate and support substrate to thereby separate the silicon substrate into two pieces at a region into which the hydrogen ions have been implanted, one of the two pieces remaining on the silicon oxide film as a silicon-on-insulator active layer. The support substrate, the silicon oxide film located on the support substrate, and the silicon-on-insulator active layer formed on the silicon oxide film defines a silicon on-insulator structure. The method makes it possible to significantly reduce crystal defect density in the silicon-on-insulator active layer, which ensures that a substrate made in accordance with the method can be used for fabricating electronic devices thereon.
