Abstract

The invention relates to an ignition chamber of a quartz diffusion furnace, and belongs to the technical field of diffusion furnaces. The ignition chamber comprises an ignition chamber body; a temperature measuring couple is arranged on the ignition chamber body in a penetrating mode; a protective device used for shielding the temperature measuring couple is further arranged on the ignition chamber body; the protective device comprises a protective cover and a plurality of protective blades; the protective cover is fixedly connected to the ignition chamber body, and the temperature measuring couple is located in the protective cover; and the multiple protective blades are all rotationally connected to the protective cover, are arranged in the circumferential direction and shield the protective cover. The ignition chamber has the effect of shielding the protruding part of the temperature measuring couple so as to improve the safety.

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...
