By leveraging cutting-edge technology and top-tier manufacturing practices, Dehong ensures that its products set the industry standard for quality, reliability, and performance.
Graphite Epitaxial Wafers are primarily used in the semiconductor and crystal growth industries, where they serve as substrates for epitaxial growth. The function of these wafers is to provide a stable and highly conductive surface for the deposition of thin layers of materials in the production of semiconductor devices. Due to the inherent thermal stability and resistance to high temperatures, these wafers are ideal for use in crystal growth furnaces that involve processes like Chemical Vapor Deposition (CVD) or Molecular Beam Epitaxy (MBE), where precise control of temperature and material deposition is crucial.
Graphite Crucibles, on the other hand, are used in high-temperature applications to contain molten materials during crystal growth. These crucibles can withstand extreme thermal conditions and resist chemical reactions with the substances they contain, making them indispensable in crystal growth furnaces used for the production of single-crystal semiconductors, photovoltaic cells, and other high-purity materials. They are designed to maintain structural integrity at temperatures up to 3000°C, allowing for efficient and controlled crystal growth.
Our Graphite Epitaxial Wafers and Graphite Crucibles are crafted with premium-grade graphite, known for its excellent thermal conductivity, high purity, and outstanding resistance to thermal shock. These products are precision-machined to meet strict industry standards, ensuring consistency and reliability in every piece.
Graphite Epitaxial Wafers: These wafers are designed with extremely smooth surfaces and a high degree of flatness to ensure uniform deposition during the epitaxial process. The low thermal expansion coefficient and high thermal conductivity of the graphite material provide excellent heat distribution, making the wafers highly effective in high-precision applications.
Graphite Crucibles: Our crucibles feature excellent resistance to oxidation and corrosion, ensuring they can withstand the extreme temperatures and harsh chemical environments encountered in crystal growth. The unique properties of the graphite ensure that they do not react with the molten materials, thus preventing contamination during crystal formation.
