In semiconductor manufacturing processes, the Showerhead gas distribution plate serves as a crucial component, playing an indispensable role. It is primarily used for the precise control of various reaction gases and is a vital part of thin-film deposition and etching processes. For a semiconductor enterprise like AMTD, the performance of the gas distribution plate directly impacts the quality and production efficiency of its products.
The design of the gas distribution plate aims to ensure the uniform deposition of specialty gases on the wafer surface. Through the small holes distributed on its surface, gases are evenly distributed, thereby guaranteeing the uniformity and consistency of the film layer on the wafer surface and improving the process yield. During semiconductor production, AMTD has deeply realized the significant impact of the gas distribution plate on the stability of product performance. Any non-uniformity in the film layer can lead to deviations or even failures in device performance, and a high-quality gas distribution plate can effectively prevent such issues.
From a technical perspective, gas distribution plates are subject to numerous stringent standards. The internal roughness of the holes is less than 0.4 μm, which helps reduce the resistance to gas flow and ensures that gases can pass through the small holes smoothly. AMTD strictly inspects this parameter when selecting gas distribution plates to guarantee the efficiency of gas transmission and avoid any adverse effects on the production process due to restricted gas flow.
The consistency requirement for hole diameters is that the standard deviation (STD) is less than 0.0016 mm, ensuring the uniform distribution of gases. The standard deviation of gas flow rates is less than 0.025 Torr, further ensuring the stability of gas flow. Additionally, the welding penetration depth ranges from 0.3 to 90 mm, and the flatness after welding is less than 0.05 mm. These parameters ensure the structural stability and reliability of the gas distribution plate. AMTD fully understands the importance of these parameters and conducts rigorous inspections and controls during the procurement and acceptance of gas distribution plates.
Different types of gas distribution plates, such as multi-layer welded gas distribution plates, double-helix nano-coated gas distribution plates, heated chamber gas distribution plates, and chamber cross-hole welded gas distribution plates, each have their own characteristics and applicable scenarios. AMTD selects the appropriate type of gas distribution plate based on different production process requirements. For example, in processes requiring high-precision gas distribution, a double-helix nano-coated gas distribution plate may be chosen. Its special coating process enhances surface uniformity and corrosion resistance, better meeting production requirements.
As semiconductor technology continues to advance, the performance requirements for gas distribution plates are also increasing. AMTD will continuously monitor the development trends in gas distribution plate technology and establish long-term partnerships with high-quality suppliers to ensure that, in future semiconductor manufacturing, gas distribution plates can meet the demands for higher precision, better corrosion resistance, and longer service life. Meanwhile, AMTD will also continuously optimize its own manufacturing processes and quality control measures to adapt to the requirements of advanced semiconductor manufacturing processes.
