  • Patent number: 8153207
    Abstract: A silicon oxide of a film thickness of about 50 nm is formed on a surface of a silicon substrate by thermal oxidation. Silver is implanted into the silicon oxide with implantation energy of about 30 keV by a negative ion implantation method. By subjecting the silicon oxide, into which the silver has been implanted, to heat treatment at a temperature of not lower than 200° C. and lower than the melting point of silver, silver particles are formed. By oxidizing the surface portions of the fine particles by heat treatment in an oxidizing atmosphere, silver oxide is formed as a coating layer.

  • Patent number: 7879704
    Abstract: A memory function body has a medium interposed between a first conductor (e.g., a conductive substrate) and a second conductor (e.g., an electrode) and consisting of a first material (e.g., silicon oxide or silicon nitride). The medium contains particles. Each particle is covered with a second material (e.g., silver oxide) and formed of a third material (e.g., silver). The second material functions as a barrier against passage of electric charges, and the third material has a function of retaining electric charges. The third material is introduced into the medium by, for example, a negative ion implantation method.

  • Patent number: 7851777
    Abstract: A resistance-changing function body includes an object made of a first substance and interposed between a first electrode and a second electrode, and a plurality of particles made of a second substance and arranged within the object so that an electrical resistance between the first electrode and the second electrode is changed before and after application of a specified voltage to between the first electrode and the second electrode. The first substance makes an electrical barrier against the second substance. With this constitution, by applying a specified voltage to between the first electrode and the second electrode, the electrical resistance can be changed depending on a state of the particles made of the second substance. Also, by virtue of a simple structure, a resistance-changing function body of small size is provided with low cost.
