  1. Silicon Mirror Polishing Silicon mirrors play a crucial role in laser systems. To achieve both flatness and subnanometer-level roughness, chemical mechanical polishing (CMP) is commonly used. We’ll explore how CMP processes impact flatness and roughness simultaneously.

  2. Strip Steel Flatness Control In cold rolling mills, maintaining strip flatness is essential for quality strip steel production. However, comprehensive research on influencing factors and effective methods for improving flatness in four-high skin pass rolling mills is lacking.

  3. Wafer Flatness in CMP Wafer flatness significantly affects semiconductor manufacturing. We’ll discuss the importance of a flatness model for optimizing CMP process variables and ensuring wafer surface uniformity.

  4. Conclusion Enhancing flatness is a multidisciplinary challenge with applications spanning materials science, optics, and manufacturing. By understanding the underlying mechanisms and employing tailored techniques, we can achieve flatter surfaces across diverse industries.
