  • Patent number: 7884367
    Abstract: A polycrystalline Si thin film and a single crystal Si thin film are formed on an SiO2 film deposited on an insulating substrate. A polycrystalline Si layer is grown by thermally crystallizing an amorphous Si thin film so as to form the polycrystalline Si thin film. A single crystal Si substrate, having (a) an SiO2 film thereon and (b) a hydrogen ion implantation portion therein, is bonded to an area of the polycrystalline Si thin film that has been subjected to etching removal, and is subjected to a heating process. Then, the single crystal Si substrate is divided at the hydrogen ion implantation portion in an exfoliating manner, so as to form the single crystal Si thin film. As a result, it is possible to provide a large-size semiconductor device, having the single crystal Si thin film, whose property is stable, at a low cost.

  • Patent number: 7884699
    Abstract: A variable resistor element comprising a first electrode, a second electrode, and a variable resistor positioned between the first and second electrodes, and changing in electric resistance when a voltage pulse is applied between the both electrodes, has posed problems that it has a restriction of having to use noble metal electrodes as an electrode material and is not compatible with a conventional CMOS process. A variable resistor element using an oxynitride of transition metal element as a variable resistor exhibits a stable switching operation, is satisfactory in data retaining characteristics, and requires a small programming current. Since it does not necessarily require noble metal as an electrode material, it is high in compatibility with the existing CMOS process and easy to produce. It can be formed by a simple step of forming a variable resistor material into a film by oxidizing a lower electrode surface consisting of conductive nitride.
