  • Publication number: 20080157912
    Abstract: This invention discloses a monolithic inductor including a body made by compressing a magnetic powder, a coil positioned in the body, and a permanent magnet positioned in the body and in a magnetic circuit formed by applying current to the coil. The monolithic inductor of this invention includes the magnetic body containing the permanent magnet and the coil. The permanent magnet in the magnetic circuit (path of magnetic flux lines) formed by applying current to the coil generates a reverse-bias magnetic field, thereby increasing the operating range of the magnetic body, the saturation current of the magnetic body, and the rated current of the inductor.

  • Publication number: 20050093084
    Abstract: A MOSFET includes a gate having a high-k gate dielectric on a substrate and a gate electrode on the gate dielectric. The gate dielectric protrudes beyond the gate electrode. A deep source and drain having shallow extensions are formed on either side of the gate. The deep source and drain are formed by selective in-situ doped epitaxy or by ion implantation and the extensions are formed by selective, in-situ doped epitaxy. The extensions lie beneath the gate in contact with the gate dielectric. The material of the gate dielectric and the amount of its protrusion beyond the gate electrode are selected so that epitaxial procedures and related procedures do not cause bridging between the gate electrode and the source/drain extensions. Methods of fabricating the MOSFET are described.

  • Patent number: 6569346
    Abstract: A ferrite with a high permeability and a high dielectric constant is introduced. Raw material powders, such as TiO2, Fe2O3 and the oxide of Mn, Ni, Cu, Mg, Li or Zn is prepared and combined in the proportion Tix(MFe2O4+2x/y)y, where x+y=1 and 0<×<1. M is any one of a mixture of metals selected from Mn, Ni, Cu, and Zn. The ratio between x and y can be adjusted according to practical needs to obtain ferrites with different permeabilities and dielectric constants. The ferrite can simultaneously be a magnetic material and a dielectric material in an electronic element. This can avoid the possible drawbacks due to sintering of two different materials in the prior art.
