  • Publication number: 20090127095
    Abstract: A method of the present invention for forming fine particles includes forming fine particles on a substrate by supplying, in the presence of inert gas, to the substrate, atoms or molecules of a supply material capable of being combined with a material constituting a surface of the substrate to produce a compound, the atoms or the molecules being supplied from a supply source. The supply source is positioned in such a manner as not to be directly connected by a line with the surface of the substrate where the fine particles are to be formed, and a high-frequency voltage varying positively and negatively, ranging from 100 kHz to 100 MHz, is applied to at least one of the substrate and a substrate supporter for supporting the substrate. This realizes a method for forming fine particles that allows forming highly uniformed magnetic fine particles with a periodic pattern through a simple process at a time.

  • Patent number: 7536706
    Abstract: A system includes additional information together with a video stream, where the additional information is related to at least one of the frames. Preferably the additional information is related to an object within the frame. A receiver receives the video and additional information and decodes the video in the same manner independently of whether the additional information is provided. The additional information is selectively presented to a viewer at approximately the time of receiving the frames. The system may also present information to a viewer from a unitary file containing an image and additional information associated with the image. A selection mechanism permits the selection of objects in the image for which the additional information is related thereto. A presentation mechanism provides the additional information to a viewer in response to selecting the object.

Then, a gate electrode of a low voltage drive thin film transistor and a mask film for covering a region constituting a channel of a high voltage drive thin film transistor are formed with a molybdenum film on the first insulating film. An impurity is implanted into a semiconductor film while using the gate electrode and the mask film as a mask, thereby forming a high density impurity region. Thereafter, the impurity is activated by performing a thermal process under a condition at 500° C. and for 2 hours, for example. Subsequently, the mask film is removed and a second insulating film is formed. A gate electrode of the high voltage drive thin film transistor is formed with an aluminum alloy on the second insulating film.
