Structure and Design: CVD furnaces typically consist of a furnace body, heating system, protective gas system, reaction gas system, and vacuum system. Among them, the furnace body adopts high-purity quartz tubes, stainless steel tubes or corundum tubes as the inner furnace, ensuring the purity of the furnace environment. The heating element uses U-shaped resistance wire, silicon molybdenum rod or silicon carbon rod to achieve efficient heating effect. In addition, its detachable three sided sealing method not only facilitates operation, but also ensures good cleanliness and vacuum degree.
High temperature working environment: CVD furnaces usually provide a high temperature environment, suitable for thin film growth and deposition processes at high temperatures. The working temperature range usually ranges from a few hundred degrees Celsius to several thousand degrees Celsius, and is adjusted according to different application requirements. At the same time, the product also adopts PID programming technology, which has high temperature control accuracy, small thermal inertia, temperature overshoot, reliable performance, and simple operation.
Chemical reaction control: The CVD furnace achieves precise control of the thin film deposition process by controlling the concentration of chemical substances in the gas phase and reaction conditions. It is possible to adjust parameters such as gas-phase flow rate, reaction pressure, and reaction time to achieve the desired film composition, structure, and performance.
High uniformity and reproducibility: The CVD furnace has good temperature uniformity and gas phase mixing uniformity, which can achieve uniform deposition of large-area substrates, while also having good reproducibility, ensuring the consistency and stability of the deposited film.
Multifunctionality: CVD furnaces can be used for various types of thin film deposition, including the deposition of different materials such as metals, oxides, nitrides, carbides, etc. The deposition and growth of different materials can be achieved by selecting different precursor gases and reaction conditions.
Wide range of applications: CVD furnaces have a wide range of applications, including the development of carbon nanotubes, coating on crystalline silicon substrates, and controllable growth of nano zinc oxide structures. In addition, it can also be used for extended welding of metal materials and heat treatment under vacuum or protective atmosphere. Widely used in the fields of semiconductors, optoelectronics, materials science, etc., for preparing various functional thin films and nanostructured materials, such as transistors, solar cells, LED devices, sensors, coating materials, etc. It is also widely used in fields such as thermal processing, cement, building materials, pharmaceuticals, analytical chemistry, and coal quality analysis.
Environmental performance: Some CVD furnaces adopt energy-saving and environmentally friendly designs and processes, which can reduce exhaust emissions and resource consumption, meeting environmental requirements.
CVD furnace has the characteristics of high-temperature working environment, chemical reaction control, high uniformity and reproducibility, multifunctionality, wide applicability, automation and intelligence, environmental performance, etc. It is an important thin film deposition equipment with broad application prospects in various fields.Click to learn more CVD system!
