  • Patent number: 7579612
    Abstract: Disclosed herein are new resistive memory devices having one or more buffers layer surrounding a dielectric layer. By inserting one or more buffer layers around the dielectric layer of the device, the resistive ratio of the device is highly enhanced. For example, tests using this unique stack structure have revealed a resistance ratio of approximately 1000× over conventional electrode-dielectric-electrode stack structures found in resistive memory devices. This improvement in the resistance ratio of the resistive memory device is believed to be from the improved interface coherence, and thus smoother topography, between the buffer layer(s) and the dielectric layer.

  • Patent number: 7505181
    Abstract: A method of operating an optical module/printer module system through a changer such that either the optical module or the printer module is driven. A first module and a second module is defined such that if the first module is an optical module, the second module is a printer module and if the first module is a printer module, the second module is an optical module. The operating method includes the following steps. In step one, the changer engages with the first module and drives the first module. In step two, the changer rotates so that the changer detaches from the first module and engages with the second module. In step three, the changer drives the second module.

  • Patent number: 7504726
    Abstract: The present invention provides a chip and its manufacturing methods and applications. Regarding the chip, there are several solder bumps on the backside of the chip. The difference of the invented chip from the convention chips is that the solder bumps are embedded in an insulting layer and a thermal-plastic material layer of the invented chip backside and separated by a conductive layer from the insulting layer and thermal-plastic material layer. Additionally, there are some end members in the insulting layer, and the end member corresponds to one solder bump. Through the present invention, chips with different functions can be integrated together, so that the needs for having portable communication devices lighter and smaller would be met.

  • Patent number: 7372169
    Abstract: The present invention discloses a dense arrangement in the conductors of a package and the corresponding conductive pads of a circuit board. The conductors and the corresponding conductive pads are separated into at least a first group in a peripheral region of the grid array package, and a second group in another region of the grid array package. Most in the first group of conductive pads are apart at a first pitch, most in the second group of conductive pads are apart at a second pitch which is less than the first pitch. According to the shrinking in the conductive trace on a conductive layer and the shrinking in the through hole, the first pitch and the second pitch are optimized for the maximum conductors and the corresponding conductive pads.
