  • Patent number: 8946742
    Abstract: The substrate with through silicon plugs (or vias) described above removes the need for conductive bumps. The process flow is very simple and cost efficient. The structures described combines the separate TSV, redistribution layer, and conductive bump structures into a single structure. By combining the separate structures, a low resistance electrical connection with high heat dissipation capability is created. In addition, the substrate with through silicon plugs (or vias, or trenches) also allows multiple chips to be packaged together. A through silicon trench can surround the one or more chips to provide protection against copper diffusing to neighboring devices during manufacturing. In addition, multiple chips with similar or different functions can be integrated on the TSV substrate. Through silicon plugs with different patterns can be used under a semiconductor chip(s) to improve heat dissipation and to resolve manufacturing concerns.

  • Patent number: 8947992
    Abstract: Combined echo and crosstalk cancellation is provided. Frequency domain adaptive filters are used to remove or reduce the effects of echo and crosstalk for a multi-channel and full-duplex communications system. Data from each transmit channel is buffered and converted to the frequency domain. The frequency domain data is multiplied by crosstalk coefficients to obtain a frequency domain correction signal for each channel. Adaptation of the crosstalk coefficients is based on correlations between the error signals and the data from each of the transmit channels. A single frequency domain transform engine, such as a Fast Fourier Transform engine, is employed for all calculations to save power and area.

  • Patent number: 8943888
    Abstract: This invention is related to a microfabricated microelectromechanical systems (a.k.a. MEMS) silicon thermal mass flow sensor integrated with a micromachined thermopile temperature sensor as a flow inception detection sensor. The micromachined thermopile sensor is used to detect the inception of mass flow and therefore to trigger the operation of mass flow sensor from its hibernating mode. By this method, the battery-operated flow speed measuring apparatus can save great deal of electricity and significantly extend the life span of battery. A new design of micromachined thermopile sensor with serpentine shape is used to reduce the complexity of microfabrication process and to increase the flexibility and options for material selection.
