Description

technical field [0001] The present application relates to the field of diffusion furnaces, in particular to an ignition chamber of a quartz diffusion furnace. Background technique [0002] Diffusion refers to the phenomenon that substance molecules transfer from high-concentration areas to low-concentration areas until they are uniformly distributed, and the rate is proportional to the concentration gradient of the substance. Diffusion is a phenomenon of mass transfer due to the thermal motion of molecules, mainly due to density differences. Diffusion technology is a basic and important semiconductor technology. [0003] Diffusion technology is mainly used to form base emitter and collector regions in bipolar devices, source and drain regions in MOS devices, polysilicon doping, etc. Diffusion technology is also called doping, which means doping one substance into another to form a p-n junction. [0004] For example, in the mass-produced crystalline silicon solar cell manu...
