  • Patent number: 7526861
    Abstract: A composite conductive film formed of a polymer-matrix and a plurality of conductive lines less than micro-sized and its fabricating method are provided. The conductive lines are arranged parallel and spaced apart from each other so as to provide anisotropic conductivity. The present conductive film can serve as an electrical connection between a fine-pitch chip and a substrate. Additionally, an adhesive layer is formed on two opposite sides of the conductive film along its conductive direction to increase adhesive areas. The strength and reliability of the package using the conductive film are thus enhanced.

  • Publication number: 20080294691
    Abstract: Methods for generating and playing a multimedia file and a recording medium storing the multimedia file are provided. In the generating method, multimedia data to be written in the multimedia file is generated, and then a media chunk for storing the multimedia data is generated. Next, a metadata chunk including metadata that describes the characteristics of the media chunk and the multimedia data is generated by analyzing the characteristics of the media chunk. Afterwards, the metadata chunk and the media chunk are written into the multimedia data file. When all the media chunks have been written, the multimedia file is scanned and the metadata chunks therein are read, such that an index table recording the relations among the multimedia data is generated in the multimedia file. Therefore, the procedure for generating the multimedia file is simplified and the time for preparing the play of the multimedia file is reduced.

  • Patent number: 7163885
    Abstract: A method for dispersing and fixing particles on the bumps of a chip using an electrophoresis technology is provided. The particles and chip bumps are processed to carry charges by applying chemical bonding between metal and thiol with electric charges. The chip is placed in a reactor with a solution along with the conductive particles. The conductive particles are then migrated and fixed to the bonding locations on the bumps of a chip through an electrophoresis procedure. For conductive particles not carrying charges, they can sink naturally to the surface of chip bumps due to their higher density than water in the solution. An electroplating procedure is then applied to fix the conductive particles onto the bump.
