In 2026, the global semiconductor industry maintains a steady expansion trend. The construction of 8-inch and 12-inch wafer production lines in Asia, Europe and North America is accelerating, and the advanced process iteration of chips drives the continuous upgrading of supporting manufacturing equipment and consumable materials. In the core links of semiconductor wafer manufacturing such as high-temperature diffusion, ion implantation and vacuum heat treatment, ultra-high-purity isostatic graphite components are required as heating and bearing materials. Different from industrial ordinary graphite, semiconductor-grade isostatic graphite has ultra-high requirements in terms of purity, density, structural uniformity and dimensional precision, and is a typical high-value-added and high-technical-barrier graphite product.
Semiconductor manufacturing processes are extremely sensitive to material impurities. Trace metal elements such as iron, copper and sodium in graphite will cause wafer contamination, chip circuit failure and performance degradation, directly affecting the yield rate of semiconductor products. Therefore, semiconductor-grade isostatic graphite requires ultra-high purity with carbon content higher than 99.995%, and the content of various harmful impurities needs to be controlled at the ppb level. At the same time, isostatic pressing technology ensures that the graphite material has uniform density in all directions, stable thermal expansion coefficient and excellent high-temperature creep resistance, which can maintain long-term stable operation in ultra-high vacuum and high-temperature semiconductor processing environment.
At present, the global supply capacity of semiconductor-grade ultra-high-purity isostatic graphite is extremely scarce. For a long time, the global high-end semiconductor graphite market is monopolized by a few international leading enterprises, resulting in long-term shortage and high price of products. With the continuous expansion of global wafer production capacity, the market demand for semiconductor special graphite components has increased sharply, and the market supply gap is further widened. Many semiconductor equipment manufacturers and wafer factories face the problems of long order delivery cycle and insufficient raw material supply, which restrict the capacity release of the global semiconductor industry.
The production of semiconductor-grade isostatic graphite has multiple core technical bottlenecks. First, ultra-high purification technology is required to remove trace harmful impurities in raw materials. Second, precise isostatic pressing forming technology is needed to ensure uniform density of blank materials. Third, high-precision machining technology is required to meet the micron-level dimensional tolerance requirements of semiconductor equipment components. Fourth, strict batch consistency control is needed to ensure stable performance of each batch of products. These technical barriers make it difficult for ordinary graphite enterprises to enter the semiconductor high-end market.
Jincheng Graphite has broken through the technical monopoly of international leading enterprises after years of independent research and development, and successfully realized mass production of ultra-high-purity semiconductor-grade isostatic graphite products. The enterprise optimizes the whole production process from raw material selection, ultra-high temperature purification, isostatic pressing forming, high-temperature graphitization to precision finishing, and strictly controls every link of impurity removal and quality detection. The carbon content of the produced semiconductor-grade graphite products is stably higher than 99.996%, and all impurity indicators meet the international advanced semiconductor industry standards.
In terms of product processing, Jincheng Graphite has introduced high-precision CNC machining equipment, which can complete micron-level precision processing of semiconductor graphite components, meeting the ultra-high precision assembly requirements of semiconductor equipment. The enterprise's semiconductor special graphite products include wafer carrying trays, diffusion furnace graphite barrels, heating components and heat insulation parts, which are widely applicable to wafer manufacturing processes of different process nodes. All products have passed the strict certification of international semiconductor industry standards.
At present, Jincheng Graphite's semiconductor-grade ultra-high-purity graphite components have been exported to many semiconductor manufacturing bases in the world, providing stable and high-quality core consumable materials for international wafer factories and semiconductor equipment manufacturers. Relying on independent technical advantages and stable product quality, the enterprise has broken the international market monopoly and become an important new supplier in the global high-end semiconductor graphite market. In the future, Jincheng Graphite will continue to deepen technical research, optimize product performance, and help the global semiconductor industry achieve stable capacity expansion and technological iteration.
