Granite is a common material that is used in various industries due to its durability, strength, and ability to resist wear and tear. One of the applications of granite is in the semiconductor manufacturing process where it is used as a substrate for the production of microchips, integrated circuits, and other electronic components.
One of the essential components of semiconductor manufacturing is photolithography, which involves the use of light to transfer patterns onto the silicon wafer. The granite plates are used in this process as a base where the thin film used to transfer the patterns is coated. Granite is preferred in photolithography because of its natural flatness, which ensures that the thin film applied on its surface is smooth and uniform. A smooth and uniform application of the thin film is critical in ensuring that the patterns created on the wafer are accurate and precise.
Granite is also used in the fabrication of cleanroom workbenches and equipment. During the production of semiconductors, cleanliness is of utmost importance, and any small particles or dust can damage the components. Therefore, the materials used in cleanrooms need to be non-shedding, non-reactive, and easy to clean. Granite meets these requirements, making it a perfect material for the production of workbenches and other equipment in the cleanroom.
Another use of granite in semiconductor manufacturing is in the construction of vacuum systems. The vacuum system is essential in the manufacturing process as it is used to create a low-pressure environment that ensures that the semiconductor components produced are of high quality. The high strength and low coefficient of thermal expansion of granite make it a reliable material for vacuum chamber construction.
In conclusion, granite is a valuable material in semiconductor manufacturing due to its exceptional properties such as durability, strength, and thermal stability. The flatness and natural cleanliness of granite make it suitable for photolithography, cleanroom workbenches, and vacuum systems. The use of granite in the semiconductor industry is a testament to its versatility and adaptability to various applications, proving that it is not just a decorative material but also an essential component in various industrial processes.
