  • Patent number: 8337615
    Abstract: A method of making a single-crystalline Si wafer with an approximately polygonal cross section and having a material property that is the same as a zone-pulled Si crystal, and the single-crystalline Si wafer. The method includes pulling at least one bottle neck of a crystal vertically downwards from a rotating hanging melt drop. The rotational speed of the crystal is reduced to between 0 and less than 1 rpm. In a crystal-growth phase, a Si single crystal ingot is pulled vertically downwards with an approximately polygonal cross section. An inductor is used to generate a temperature profile at a growth phase boundary of the crystal that corresponds to the shape of a cross section of the pulled Si single crystal ingot. The growth is ended at a desired pulling length and the Si single crystal ingot is cut into wafers having an approximately polygonal cross section.

  • Patent number: 8340525
    Abstract: A method for stabilizing multi-channel optical signal wavelengths includes the following steps. A first detecting signal is stacked on a plurality of driving signals in sequence. A plurality of optical signals generated after being driven by the plurality of driving signals is combined into one optical total signal. A wavelength detection is performed on the optical total signal. A second detecting signal with a frequency band the same as that of the first detecting signal is extracted from the signals obtained after the wavelength detection. The wavelength of the optical signal in the corresponding channel among the multiple channels is controlled according to the second detecting signal. A device for stabilizing multi-channel optical signal wavelengths is also provided. Using the above method or device, the multi-channel optical signal wavelengths can be stabilized, which requires less elements, and has a simple circuit structure, a high integration level, and a low cost.
