Semiconductor Equipment Parts Supplier | High Purity Titanium, Molybdenum & Refractory Metal Machining

The semiconductor chip production line is an extremely harsh environment that consumes ordinary metals. The fluorine and chlorine gases flowing within the etching machine chamber, the continuous high temperature of up to 800°C in the ion implantation process, and the strict cleanliness requirements in the vacuum coating equipment all cause traditional stainless steel materials to fail rapidly. For semiconductor equipment manufacturers, finding stable and highly responsive suppliers of high-purity titanium and refractory metals is crucial for ensuring the yield of the production line. Based on this demand, China Super Tech Co., Ltd. has established a comprehensive metal supply chain and processing system covering titanium, molybdenum, tantalum, niobium, and tungsten.

Our operation model is not merely material trading; it is an engineering service aimed at addressing the actual production pain points. In the third quarter of last year, the etching machine manufacturers in the Asia-Pacific region encountered severe yield fluctuations. Due to the long-term erosion of fluorine-based plasma, the stainless steel liner originally configured by the original factory showed slight corrosion, resulting in the scrapping of hundreds of wafers every month. The customer sent urgent orders to us. Instead of going through the lengthy raw material procurement cycle, we directly took Gr2 high-purity titanium plates from the inventory. With the regular 0.5mm to 50mm thickness spot reserves, our five-axis CNC workshop immediately started production, turning the titanium plates into gas spray heads with precise air holes, and completed the electrolytic polishing treatment within 24 hours. The data statistics after three months of the parts being installed showed that the scrap rate caused by particle contamination decreased by 70%, and the customer's production yield increased by 1.8 percentage points. This 7-day rapid delivery proved the importance of the spot inventory for emergency maintenance (PM) in the semiconductor industry.

This rapid response capability is also demonstrated in the application of high-temperature resistant components. An ion implantation equipment manufacturer in Europe once encountered a technical bottleneck: when the equipment operated at 850℃, the original components underwent high-temperature creep, resulting in deviations in the ion beam alignment accuracy. To address this situation, we recommended and activated the TZM molybdenum alloy inventory. This molybdenum alloy, which contains titanium and zirconium elements, has a high-temperature strength that is over 30% higher than that of ordinary molybdenum. We used the slow wire-cutting process to fabricate extremely precise beam stoppers. After a year of continuous operation tracking, the size of this component remained stable, and no deformation occurred, completely solving the problem of precision drift of the customer's equipment under high temperatures.

In the domestic Mini-LED manufacturing field, thermal field uniformity is the key factor determining costs. An LED epitaxial factory needs to optimize the heating structure of the MOCVD equipment. We use a 200mm pure molybdenum circular plate and, through precise CNC machining on the surface, create concentric ring-shaped groove structures. This design not only solves the thermal deformation problem during the 1100℃ heating and cooling process, but also significantly increases the thermal contact area, thereby greatly improving the uniformity of the epitaxial growth film thickness and meeting the requirements of large-scale mass production for customers.

The rapid completion of these production processes is supported by the solid underlying capabilities of China Super Tech Co., Ltd. We have a large amount of stock of various specifications of metal materials in our warehouse, including Gr1/Gr2 high-purity titanium, Gr7 corrosion-resistant titanium alloy, TC4 titanium alloy, as well as Mo1 pure molybdenum, TZM molybdenum alloy, Ta1 pure tantalum, Nb1 pure niobium, and W1 pure tungsten. Whether it is a few millimeters thick sheet or a large-diameter round rod, the sufficient inventory ensures that standard products can be shipped within 24 to 48 hours at the fastest speed.
In addition to material supply, we also offer a one-stop processing service from raw materials to finished products. The company is equipped with five-axis CNC, electrical discharge machining and other equipment, which can achieve a tolerance control of ±0.005mm. At the same time, we have a post-processing production line that complies with SEMI standards, covering electrolytic polishing, ultrasonic cleaning, vacuum annealing and vacuum packaging. Customers do not need to separately connect with material suppliers, processing factories and cleaning factories. They only need to connect with us through a single point, and can complete the entire procurement process, significantly reducing communication costs and quality control risks.
