Silicon Mirror Polishing Hub

This cluster explores how chemical mechanical polishing, plasma-assisted techniques, and atom-selective etching are being engineered to achieve near-atomic smoothness on materials like silicon, diamond, and β-Ga. The posts cover interfacial regulation strategies, sheet-by-sheet removal mechanisms, and molecular dynamics insights into material removal and microstructure evolution during polishing. They also highlight industrial advances such as superflat PVD-coated silicon for optics and semiconductor-grade wafer finishing, showing how better-controlled, faster polishing directly supports cutting-edge electronics, satellite optics, and high-energy laser systems.

This cluster highlights how imaging and computation are transforming surface metrology, from semiconductor wafers to industrial finishes. Wooptix showcases ultra-fast, high-accuracy in-line wafer metrology at SPIE Advanced Lithography + Patterning 2026, emphasizing real-time process control in chip manufacturing. In parallel, research on wavelet Gaussian processes enables multi-scale monitoring of imaging data, such as DSLR-captured surface finishes, providing a rigorous probabilistic framework to detect subtle defects and texture changes across scales. Together, these developments point to a future where high-throughput imaging and advanced modeling enable continuous, non-contact quality assurance in complex manufacturing environments.
