Description

Technical Field

[0001] The present application relates to the field of semiconductor or photovoltaic material processing, and in particular to a mold auxiliary component, a mold component, and a furnace manufacturing device. Background Art

[0002] Semiconductor or photovoltaic materials are widely used in industries such as electronics and new energy. Semiconductor or photovoltaic materials usually need to undergo chemical treatment before they can be applied to products. Chemical vapor deposition (CVD) technology is one of the treatment methods. CVD technology is currently widely used in semiconductor or photovoltaic material processing. Common processing equipment includes plasma enhanced chemical vapor deposition (PECVD) equipment, low pressure chemical vapor deposition (LPCVD) equipment, atmospheric pressure chemical vapor deposition (APCVD), etc. In addition to CVD technology, there are also diffusion processes, such as phosphorus diffusion and boron diffusion. Gas diffusion can be used to process semiconductor or photovoltaic materials. There are currently many related equipment in the industry, and corresponding equipment can be selected for processing according to specific processing needs.

[0003] When processing semiconductor or photovoltaic materials, the sheet material is typically fed into a CVD tube furnace, where it undergoes a reaction under certain temperature and pressure conditions. A CVD tube furnace is a heating chamber that provides energy for the chemical reactions involved in vapor deposition in thin film fabrication. The CVD tube furnace deposits the chemical substances produced by the vapor-phase reaction onto a heated substrate to form a thin film. The furnace core of a CVD tube furnace typically requires through-holes (such as those for thermocouples, which are used to house temperature-measuring thermocouples). These holes must meet specific angle requirements.

[0004] The furnace core of a traditional CVD tubular furnace is typically manufactured using a mold. The thermocouple holes are drilled after the furnace core is formed and fabricated. During assembly, operators rely on experience and visual observation to drill the holes in the outer wall of the furnace core using an electric drill. However, manual drilling can lead to angle and position errors, which can cause the furnace core to fail and result in losses. Furthermore, due to errors in the drilling angle, manual drilling can easily damage the furnace wire. Utility Model Content
