Quartz Crucible

Semicorex quartz crucible is an essential component in the semiconductor industry, especially in processes such as single-crystal growth, where its thermal stability, purity, and resistance to high temperatures are crucial. The high-purity quartz crucible, designed specifically for single-crystal growth applications, plays a pivotal role in ensuring high-quality material production, such as single-crystal silicon. The crucible's unique properties make it an ideal choice for use in high-temperature furnaces and crystal growth environments, where precision and performance are paramount.

Semicorex quartz crucible is made from carefully refined quartz, ensuring extremely low levels of impurities. This product is primarily used in the growth of single-crystal silicon, a critical material in semiconductor devices and solar cells. The crucible is designed to withstand the high temperatures and challenging conditions found in single-crystal growth furnaces, which are essential for producing high-quality silicon wafers.

Quartz is an inherently strong material, offering both high thermal stability and excellent resistance to chemical attack. The high-purity quartz used in the manufacture of these crucibles is treated and purified to ensure that it does not introduce any contaminating elements into the growth process, thus ensuring the production of pure, high-performance single crystals.

Key Features

• High Purity: The crucible is produced using high-purity quartz, which minimizes contamination risks during the single-crystal growth process. This high level of purity is vital to the formation of flawless silicon crystals that meet the stringent requirements of semiconductor manufacturing.
• Thermal Stability: Quartz has an exceptional ability to withstand high temperatures, making it suitable for the extreme heat conditions involved in crystal growth. The crucible can endure rapid temperature changes, which are common in processes like Czochralski and floating-zone crystal growth.
• Excellent Chemical Resistance: Quartz exhibits high resistance to most chemicals, which is particularly important in the presence of molten silicon or other reactive materials during the crystal growth process. This resistance ensures the crucible remains intact and does not contaminate the material it contains.
• Low Thermal Expansion: The low coefficient of thermal expansion of quartz reduces the risk of cracking or deformation under high temperatures, making the crucible more durable and reliable during the entire growth process.
• Precision and Consistency: High-purity quartz crucibles are produced to precise specifications, ensuring uniformity in the shape, size, and wall thickness. This precision is essential for the consistent performance and successful outcomes of the single-crystal growth process.
• Extended Lifespan: Due to its high resistance to thermal stress and chemical corrosion, the high-purity quartz crucible enjoys a long service life, providing a cost-effective solution for semiconductor and crystal growth applications.
  

Applications in Single-Crystal Growth

The high-purity quartz crucible is primarily used in the growth of single-crystal silicon, which is the foundational material for various semiconductor devices, including integrated circuits (ICs), transistors, and photovoltaic cells. In this process, the crucible holds molten silicon at high temperatures, allowing it to cool and solidify into a crystal form. This crystal is then sliced into thin wafers for further processing.

Czochralski Process: In the Czochralski method, a quartz crucible holds molten silicon, which is used to form a single-crystal ingot. The molten silicon is slowly pulled up from the crucible, allowing it to form a single crystal as it cools and solidifies.

Floating-Zone Process: The floating-zone method involves a high-purity quartz crucible in which a small zone of silicon is melted and allowed to solidify into a single crystal. The process requires precise control over temperature and the purity of the crucible to avoid contamination of the growing crystal.

Production of High-Quality Silicon Wafers: The silicon produced using these methods is sliced into thin wafers, which are essential for the manufacturing of microelectronics and photovoltaic solar cells. The purity of the quartz crucible directly influences the quality of the silicon wafers and the performance of the resulting devices.

Solar Cell Manufacturing: In the solar cell industry, high-purity silicon is used to create efficient photovoltaic cells. The high-purity quartz crucible ensures that the silicon produced during the growth process is free from impurities that could negatively affect the performance of solar cells.
