Chinese Chip Toolmaker Claims Wafer Polishing Breakthrough
Chinese equipment maker Hwatsing Technology has announced China's first in-line metrology system integrated directly into chemical mechanical polishing tools for six-inch wafers. By capturing real-time measurements before and after polishing, the system feeds live operational data back to control systems to improve wafer surface uniformity and minimize material waste. Shipped to a leading domestic optical silicon supplier, this chemical mechanical polishing breakthrough demonstrates how domestic toolmakers are quietly closing critical manufacturing gaps beyond advanced lithography, enhancing overall yield for mature semiconductor production lines across China.
