Hwatsing Technology, China’s leading producer of chemical mechanical polishing equipment, announced on Thursday a new metrology system for six-inch wafers that can be integrated directly into the polishing workflow to provide ultra-precise measurements aimed at identifying defects and ensuring manufacturing consistency.
Wafer polishing integration and benefits
The company said the tool is the country’s first six-inch metrology system paired with chemical mechanical polishing equipment and can take real-time measurements before and after polishing, feeding live data back to the control system. According to Hwatsing, this direct integration could improve wafer uniformity and reduce waste, addressing inefficiencies in traditional production lines.
Deployment and industry context
Based in the northern city of Tianjin, Hwatsing reported that it had shipped the new system to an unnamed “leading domestic optical silicon materials producer.” The announcement underscores continued technical progress by Chinese chip-tool developers, even as the industry remains heavily dependent on foreign suppliers for more complex manufacturing procedures.
