  • Patent number: 8933784
    Abstract: Provided are an RF powder particle, an RF powder, and an RF powder-containing base that can make it difficult to fabricate, for example, forged documents or forged bank notes with respect to sheet-like objects having high proprietary values, such as bank notes, and that allow necessary information to be stored in each of the large number of particles which are each provided with a tank circuit having a predetermined resonant frequency. The RF powder particle includes a coil 24 (inductance element) as a magnetic filed coupling element and a condenser 25 (capacitance element) connected to the both ends of the coil on an insulating surface of a substrate 22 and is configured so as to form a tank circuit 31 by the inductance element and the capacitance element. The tank circuit 31 functions as a circuit in a resonance state or in a non-resonance state in accordance with conditions in response to a high-frequency magnetic field from outside.

  • Patent number: 8318047
    Abstract: Provided are a method for providing an RF powder that is easily handled because it is used as a powder (powdery state), not used as individual elements, and is high in applicability and extensibility, extremely low in manufacturing cost in respect of the unit price of each particle, and extremely high in practicability; and an RF powder-containing liquid. In the method for providing an RF powder, an RF powder composed of a large number of RF powder particles 11a is provided to a user in a state of being stored in a container 1. The RF powder is stored in the container 1 together with a medium that prevents the large number of RF powder particles 11a from adhering to one another.

  • Patent number: 4026742
    Abstract: A method of making a microcircuit device wherein a uniform film of electrically conductive metal is deposited on the microcircuit surface and selectively removed from areas exposed through a mask. The improvement comprises the steps of contacting the exposed metal with a reactive halogenated gas in plasma state to convert the metal to a metal halide; and removing the metal halide to form a pattern of electrically conductive metal on the device.The plasma can be generated in a reaction chamber with a high-frequency electromagnetic field. The process is useful in forming a desired pattern of metal for electrodes or wiring on a semiconductor substrate or other microcircuit base. The process is particularly useful for etching tungsten or molybdenum metal patterns.
