Precision is the key component of semiconductor equipment manufacturing. The demand for high-precision components has been increasing as the industry strives for ever-decreasing dimensions in the chips. Precision granite components play a vital role in ensuring that the equipment can achieve tolerances of a few micrometers or less.
Granite is an ideal material for producing precise components because it is hard, non-magnetic, and has excellent thermal stability. These properties enable granite to maintain dimensional stability and accuracy even under extreme conditions. Furthermore, the natural crystal structure of granite gives it excellent vibration-damping properties, which is essential in the manufacturing process of semiconductor equipment.
One of the primary applications of precision granite components is in the construction of wafer stages. The wafer stage holds the wafer during the manufacturing process and moves it precisely to the next processing step. Any inaccuracies in the stage could lead to misalignment and erroneous patterning, resulting in faulty chips that do not meet the required specifications. Precision granite components ensure that the wafer stage can move smoothly and accurately with minimal vibration, essential for the manufacturing process's success.
Another application of precision granite components is in the construction of micropositioners used in semiconductor equipment. These micropositioners allow for precise positioning of components during the manufacturing process. Ensuring precise placement of components is critical since even a tiny deviation can cause a chip to malfunction.
In conclusion, precision granite components play a vital role in the semiconductor equipment manufacturing process, enabling the industry to achieve unparalleled precision and accuracy. As the demand for smaller and more powerful chips continues to rise, the use of granite components will become increasingly crucial. These components provide the necessary stability and accuracy for the manufacturing process, ensuring that the finished chips meet the required specifications. Therefore, the importance of precision granite components cannot be overstated in the production of semiconductor equipment with ultra-precision.

 1 Ture Granite
UNPARALLELEDÂ chooses the best granite material to customize mechanical components for high-end precision machinery. We only choose granite, not marble. The physical performance of marble is not as good as that of granite, and many customers cannot tell whether the product they receive is granite or marble. It is precisely because of this that many suppliers use cheap marble to pass off as granite, thereby earning high profits. However, the physical properties of marble are far inferior to granite, so the precision of the products received by customers cannot meet the requirements, and the appearance is not as beautiful as granite.

Why Choose Granite Mechanical Structures for Semiconductor?
More and more semiconductor equipment are made by granite assembly. UNPARALLELED can manufacture granite machine bed for semiconductor equipment.
In recent years, the semiconductor industry has developed by leaps and bounds, which is inseparable from the efforts of scientists. The precision of chips produced by semiconductor equipment is also getting higher and higher. Only the more advanced the semiconductor equipment is, the more advanced the chips produced can be. The mechanical structure of semiconductor equipment cannot do without granite. The metal mechanical structure is easily affected by temperature differences and humidity, and the accuracy of equipment operation will be affected. Granite precision mechanical structures are basically not affected by temperature differences.
There are many types of stone in the world, so is every stone suitable for precision granite mechanical components? Of course not. Only a few types of granite can meet our needs. The physical properties of the granite material we choose must be superior, and its density is generally greater than 3000kg/m3. We have tested a lot of granite and have a physical performance analysis report for each stone.
Each piece of precision granite components will be carefully hand-ground to make its flatness, parallelism, straightness, verticality and other precision reach 1μm.

1. What color of granite is best? ：
When it comes to manufacturing precision granite surface plates, the color of granite used can make a significant difference in the final product. Generally speaking, the best color of granite for precision surface plates is a medium to dark grey hue with a fine-grained texture. This type of granite is known as "black granite" and is widely used in the manufacturing of surface plates due to its high stability and superior accuracy.
Black granite is a type of igneous rock that is formed from molten magma deep within the earth's crust. Its dark color results from the presence of minerals such as hornblende, biotite, and pyroxene. These minerals give black granite its characteristic fine-grained texture and make it an ideal material for precision machining and surface measurement.
One of the main reasons why black granite is the preferred choice for precision surface plates is its stability. Black granite is an extremely hard and dense rock, which means that it is less susceptible to changes in temperature, humidity, and other environmental factors that can affect the accuracy of a surface plate. This stability ensures that the surface plate will maintain its flatness and precision over time, even under heavy use.
Another key advantage of black granite is its superior accuracy. The fine-grained texture of black granite allows it to be machined to very tight tolerances, which means that the surface of a black granite surface plate will be extremely smooth and uniform. This, in turn, ensures that any object placed on the surface plate will be measured accurately, with minimal distortion or interference.
Of course, not all black granite is created equal, and there are certain characteristics to look for when selecting a granite slab for use as a surface plate. Ideally, the granite should be free from any visible defects such as cracks, pits, or seams. It should also be uniform in color and texture, with no significant variations that could affect the accuracy of the surface plate.
In conclusion, when it comes to manufacturing precision granite surface plates, black granite is undoubtedly the best choice. Its stability, accuracy, and fine-grained texture make it the ideal material for this application, and it is widely used in industries such as aerospace, automotive, and manufacturing. So, if you are looking for the best material for your precision surface plates, be sure to choose a high-quality black granite slab.
