Abstract: To manufacture a MOSFET device, first, a patterned mask is utilized to implant first ions, to form a well region in which diffusion is not easy. Then, the patterned mask and spacers on its sidewalls are utilized to implant second ions in self-alignment with a source region. Further, the characteristic that the second ions are easier to diffuse than the first ions is utilized to form a semi-superjunction located at a bottom of the well region and connected to the bottom of the well region. The semi-superjunction effectively expands a junction depth of the well region, so that a withstand voltage of the device is increased to achieve high-conduction performance of the device, and also shifts a peak of electric field strength below a gate oxide layer to below the well region, so that the electric field strength below the gate oxide layer is effectively reduced and is more uniform.

Abstract: An indoor positioning method includes judging whether a positioning terminal enters a coverage range of a virtual beacon. If yes, judging whether a distance between the positioning terminal and the virtual beacon gradually decreases to obtain a judgement result, according to the judgement result, adjusting the step size of a PDR positioning algorithm. When the distance gradually decreases, the step size of the PDR positioning algorithm is decreased, and when the distance gradually increases, the step size of the PDR positioning algorithm is increased. The positioning terminal is then positioned by a PDR positioning algorithm with the step size adjusted to obtain a positioning result. If not, the positioning terminal is positioned by a PDR positioning algorithm with the step size not adjusted to obtain a positioning result. According to the present invention positioning can be more accurate by adaptively adjusting the step size in the PDR positioning algorithm.
