Material treatment equipment for power field effect transistor processing

Abstract

The invention relates to material treatment equipment for power field effect transistor processing, which comprises a box body assembly and a heating assembly. The box body assembly is wrapped with the heating assembly. The heating assembly comprises a heating box body, an oxygen adding pipe, fire spraying pipes and an exhaust pipe. The lower end of the heating box body is connected with the oxygen adding pipe. The fire spraying pipes are installed in the heating box body, and the four fire spraying pipes are installed in the heating box body at equal intervals. The material treatment equipment for power field effect transistor processing has the beneficial effects that fuel can be fully combusted, the utilization rate of the fuel can be improved, the temperature of the equipment can be conveniently increased, meanwhile, the equipment can tightly seal a processing part and prevent external air from entering the processing part to cause waste of coke, the equipment can extract carbon monoxide generated by reaction for utilization, the equipment can separate coke from crude silicon, and the equipment can make the crude silicon contact an acid solution more fully to accelerate the purification of silicon.

Description

technical field [0001] The invention relates to the technical field of power field effect tube processing, in particular to a material processing equipment for power field effect tube processing. Background technique [0002] Power MOS field effect transistor, that is, MOSFET, its original meaning is: MOS (MetalOxideSemiconductor metal oxide semiconductor), FET (FieldEffect Transistor field effect transistor), that is, the gate of the metal layer (M) is separated by the oxide layer (O) to use the electric field The effect to control the semiconductor (S) field effect transistor, the power field effect transistor needs to use silicon as a raw material in the processing process, and silicon needs to be purified by processing equipment before it can be used, so the material processing equipment is a power field effect transistor. It is an indispensable equipment in the process of pipe processing. [0003] Existing material processing equipment cannot burn the fuel repeatedly w...
