    摘要: An interleaved flyback converter device with leakage energy recycling includes: two flyback converters and an input power. Each flyback converter includes a capacitor, a switch, two diodes, and a transformer. The input power is connected to the capacitors of the two flyback converters respectively. By using the capacitors as input voltage, the two flyback converters are provided with lower voltage rating. The diodes are used to recycle leakage energy directly, and to clamp voltage on power components. Therefore, in addition to enhancing efficiency via recycling leakage energy, the two flyback converters have lower switching losses due to lower switching voltage.

    摘要: A method for fabricating a semiconductor device is provided. A substrate comprising a P-well is provided. A low voltage device area and a high voltage device area are defined in the P-well. A photoresist layer is formed on the substrate. A photomask comprising a shielding region is provided. The shielding region is corresponded to the high voltage device area. A pattern of the photomask is transferred to the photoresist layer on the substrate by a photolithography process using the photomask. A P-type ion field is formed outside of the high-voltage device area by selectively doping P-type ions into the substrate using the photoresist layer as a mask.
