Granite is a type of hard rock that has become an indispensable material in the semiconductor manufacturing industry. Its properties allow it to withstand high temperatures, which makes it ideal for use in various stages of semiconductor device manufacturing processes. As a result, granite assembly has found extensive application areas in semiconductor manufacturing process device products.
One of the most utilized applications of granite assembly is in the construction of high-precision machine tool structures. The rigidity and stability of granite make it possible to produce precise and accurate tools with little or no deformation. This level of precision is necessary in semiconductor manufacturing processes such as ion implantation, where the beam must be accurately directed onto the wafer.
Another application of granite assembly in semiconductor manufacturing is in the construction of metrology equipment. Metrology equipment is vital in semiconductor manufacturing processes as it measures and verifies the accuracy of devices being produced. Granite's dimensional stability, low thermal expansion, and excellent vibration damping properties make it the material of choice in the construction of metrology equipment. This includes large granite surfaces used in the staging and inspection of wafers.
Optical tables are yet another area of extensive application of granite assembly in the semiconductor industry. Optical tables are used in the testing of optical devices such as waveguides for data communication. Granite's flatness, low thermal expansion, high rigidity, and mechanical stability enable it to provide a highly stable surface for the mounting and positioning of optics. Granite Optical tables can provide the stability and rigidity required to perform accurate, precise testing of optical devices.
Granite also finds application in the construction of wafer chucks and stages. During the semiconductor manufacturing process, precision alignment, and position control is crucial. Wafer chucks, which hold the wafers in place during processing, must maintain position accuracy while withstanding high temperatures and vacuum conditions. Granite has excellent dimensional stability over a wide range of temperatures and can withstand vacuum conditions, making it ideal for the construction of wafer chucks. Stages used in the movement of wafers from one position to another go through a cycling sequence of movements during a semiconductor fabrication process. Granite assembly provides stability and durability needed to bear the continuous and repetitive cycles of movement.
In summary, the application of granite assembly in the semiconductor manufacturing industry is vast. Its properties such as dimensional stability, low thermal expansion, high rigidity, and vibration damping make it an ideal material for use in various stages of semiconductor device manufacturing processes. From the construction of high-precision machine tools and metrology equipment to optical tables and wafer stages and chucks, granite's attributes play a crucial role in providing stability, accuracy, and repeatability necessary to achieve high-quality semiconductor device manufacturing.
