In the microscopic world of semiconductor manufacturing, the precision of gas distribution directly impacts wafer quality and chip performance. The Showerhead, as a crucial gas distribution device in semiconductor manufacturing processes, shoulders the important mission of uniformly distributing process gases onto the wafer surface. Its performance directly affects the yield and chip performance in semiconductor manufacturing.
The Showerhead, also known as a spray head or gas distribution disc/uniformity disc in Chinese, plays a vital role in semiconductor processes such as chemical vapor deposition (CVD) and atomic layer deposition (ALD). Process gases need to be uniformly distributed onto the wafer surface through the Showerhead to achieve uniform film growth. High-precision machining is the foundation for the Showerhead to achieve uniform gas distribution. High-precision machining equipment ensures consistent hole diameters, allowing gases to pass through the small holes with uniform flow rates and velocities, thus ensuring uniform gas spraying onto the wafer surface. This uniform gas distribution is crucial for uniform film growth in semiconductor manufacturing, as the thickness uniformity of the film directly affects the electrical performance of the chip. If the gas distribution is uneven, it will lead to inconsistent film thickness, resulting in differences in electrical performance across different regions of the chip and reducing the overall performance and reliability of the chip.
Due to the extremely high cleanliness requirements in semiconductor manufacturing, any minor impurity contamination can lead to wafer defects. Therefore, the Showerhead needs to undergo strict cleaning and treatment during the production process. From the cleaning of raw materials to anti-pollution measures during processing and final cleaning of finished products, every step needs to be strictly controlled to ensure the product is free of impurities and contamination. A high-cleanliness Showerhead can prevent impurities from adhering to the wafer surface, thereby improving wafer manufacturing quality and yield. In addition, multiple composite surface treatment processes are also important means to enhance Showerhead performance. Sandblasting can increase surface roughness and improve gas distribution uniformity; anodizing can form a dense oxide film, enhancing surface corrosion and wear resistance; brush plating and electrolytic polishing can further improve surface quality and extend product service life.
