In semiconductor manufacturing processes, temperature is one of the key factors affecting wafer processing quality and chip performance. The heater disc, as a key component in semiconductor equipment, shoulders the important task of precisely controlling process temperatures. The accuracy and stability of its temperature control directly determine the quality and efficiency of semiconductor manufacturing processes.
The heater disc is mainly used in semiconductor film equipment to control the wafer process temperature by heating the base metal. It ensures process consistency through high-temperature uniformity, thereby improving chip production quality. In semiconductor processes such as film deposition, etching, and annealing, precise temperature control is required. For example, in film deposition processes, temperature changes affect the growth rate, structure, and performance of the film; in etching processes, temperature fluctuations lead to uneven etching rates, affecting etching accuracy and selectivity. Therefore, the heater disc needs to have precise temperature control capabilities to accurately control the wafer process temperature within the set range.
The rated parameters of the heater disc can be customized according to customer needs, providing various voltage and power options to meet heating requirements in different scenarios. In terms of structure, the heater disc adopts a cold-end design, which effectively insulates heat to prevent heat transfer to the external environment, ensuring operator safety and improving energy efficiency. The cold-end design usually uses special insulation materials and structural designs to isolate the heating area from the external environment and reduce heat loss. Various connection methods ensure stable and reliable electrical connections and reduce failure rates. The heater disc can adopt multiple connection methods such as metal tube connections and thermal joints + silicon sleeves. These connection methods have good electrical performance and mechanical stability, ensuring safe and reliable operation of the heater disc during work.
In terms of materials, aluminum alloy heater discs and stainless steel heater discs have their own advantages. The aluminum alloy heater disc, made of high-purity aluminum alloy, has excellent thermal conductivity and lightweight characteristics, enabling rapid and uniform heating and efficient energy utilization, suitable for high-precision temperature control scenarios. High-purity aluminum alloy has good thermal conductivity, quickly transferring heat to the wafer surface. Its lightweight characteristics reduce the equipment load and improve equipment operation efficiency. The stainless steel heater disc, made of corrosion-resistant stainless steel, has excellent high-temperature stability and chemical corrosion resistance, suitable for long-term stable operation in harsh industrial environments. In semiconductor manufacturing, some process environments may contain corrosive gases or liquids, and the corrosion resistance of the stainless steel heater disc ensures its long-term stable operation in such harsh environments.
