  • Publication number: 20120009740
    Abstract: A method of manufacturing a SOI high voltage power chip with trenches is disclosed. The method comprises: forming a cave and trenches at a SOI substrate; filling oxide in the cave; oxidizing the trenches, forming oxide isolation regions for separating low voltage devices at the same time; filling oxide in the oxidized trenches; and then forming drain regions, source regions and gate regions for a high voltage power device and low voltage devices. The process involves depositing an oxide layer overlapping the cave of the SOI substrate. A SOI high voltage power chip thus made will withstand at least above 700V voltage.

  • Publication number: 20110316073
    Abstract: The present invention discloses an SOI CMOS device having a vertical gate structure, comprising: an SOI substrate, and an NMOS region and a PMOS region grown on the SOI substrate, wherein the NMOS region and the PMOS region share one vertical gate region, said vertical gate region lying in the same plane as the NMOS region and the PMOS region and between the NMOS region and the PMOS region; a gate oxide layer is arranged between the vertical gate region and the NMOS region for isolation; and a gate oxide layer is arranged between the vertical gate region and the PMOS region for isolation. The present invention occupies small area, contains less pattern layers, requires a simple process, has an open body region that can completely avoid the floating effect of the traditional SOI CMOS device, and is convenient to parasitic resistance and capacitance tests.

  • Publication number: 20090112580
    Abstract: The speech processing apparatus configured to split a first speech waveform and a second speech waveform into a plurality of frequency bands respectively to generate a first band speech waveform and a second band speech waveform each being a component of each frequency band; determine an overlap-added position between the first band speech waveform and the second band speech waveform by the each frequency band so that a high cross correlation between the first band speech waveform and the second band speech waveform is obtained; and overlap-add the first band speech waveform and the second band speech waveform by the each frequency band on the basis of the overlap-added position and integrates overlap-added band speech waveforms in the plurality of frequency bands over all the plurality of frequency bands to generate a concatenated speech waveform.
