  • Patent number: 11404305
    Abstract: A manufacturing method a semiconductor device includes the following steps. A first mask pattern and a second mask pattern are formed on a first region and a second region of a substrate respectively. The second region is located adjacent to the first region. A top surface of the first mask pattern is lower than a top surface of the second mask pattern in a thickness direction of the substrate. A trench is formed in the substrate. The trench is partly located in the first region and partly located in the second region. A first etching process is performed for reducing a thickness of the second mask pattern and reducing a height difference between the top surface of the first mask pattern and the top surface of the second mask pattern in the thickness direction of the substrate. An isolation structure is formed in the trench after the first etching process.

  • Patent number: 9763005
    Abstract: The present disclosure illustrates an acoustic echo cancellation method and system using the same. The acoustic echo cancellation method comprises the following steps. Firstly, a prior-knowledge matrix comprising a plurality of space vectors is built. Then, an initial filter vector is generated by the prior-knowledge matrix and an initial weighting vector. The weighting vector is updated based on the difference of the echo signal and the estimated signal in an iteration algorithm, and the coefficient of the filter vector is updated according to the updated weighting vector. An estimated signal is generated according to the updated filter vector and the original signal. Finally, the next echo signal is cancelled by the near-end estimated signal.
