    摘要: A termination for silicon superjunction VDMOSFET comprises heavily doped N-type silicon substrate which also works as drain region; drain metal is disposed on the back surface of the heavily doped N-type silicon substrate; an N-type silicon epitaxial layer is disposed on the heavily doped N-type silicon substrate; P-type silicon columns and N-type silicon columns are formed in the N-type silicon epitaxial layer, alternately arranged; a continuous silicon oxide layer is disposed on a part of silicon surface in the termination; structures that block the drift of mobile ions (several discontinuous silicon oxide layers arranged at intervals) are disposed on the other part of silicon surface in the termination. The structures that block the drift of mobile ions disposed in the termination region are able to effectively prevent movement of the mobile ions and improve the capability of the power device against the contamination induced by the mobile ions.

    摘要: The low power consumption CMOS high voltage driving circuit relates to a kind of high voltage driving circuit for output driving, and there is an out buffer stage between the output end of the level switch stage and the input end of the high voltage output stage, comprising a high voltage PMOS pipe and a high voltage NMOS pipe. The source of the high voltage PMOS pipe is connected with the power supply, its gate electrode is connected with the output end of the upper level out buffer unit as the input end of the current level out buffer unit. The source of the high voltage NMOS pipe is put to earth, and its gate electrode serves as the receiving end of the 3ith sequence signal. The drain region of the high voltage PMOS pipe is connected with that of the high voltage NMOS pipe and is connected with the input end of the lower level out buffer unit as the output end of the current level out buffer unit. The input end of the first out buffer unit is connected with the output end of the level switch stage as the input end of the out buffer stage, and the output end of the final output buffer unit is connected with another input end of the high voltage output stage as the output end of the out buffer stage.

    摘要: A vertical lighting vaneless inverter fan comprises a body, a blast system, an air supply column, a lighting device and a sound-reducing structure. The blast system is mounted in the inner chamber of body. The air supply column is installed on the top of body. The blast system supplies air to the air supply column, the airflow is jetted from the air supply column. The impeller is located above the motor. When the blast system is installed in the inner chamber of body case, the impeller corresponds to the bottom of air outlet, so that the wind can be delivered through the air outlet directly.
