Hwatsing Technology unveils China's first CMP-integrated 6-inch wafer metrology system
Synopsis
Key Takeaways
Hwatsing Technology, China's leading producer of chemical mechanical polishing (CMP) equipment, announced on Thursday, 7 August 2026 a new metrology system for six-inch wafers — marking the country's first in-line measurement tool paired directly with CMP equipment. The Tianjin-based company said the system has already been shipped to an unnamed leading domestic optical silicon materials producer, signalling early commercial traction.
What the breakthrough involves
Wafers are thin, flat silicon discs that serve as the base for microchips, integrated circuits, and electronic devices. Transforming a raw wafer into a finished chip demands multiple precision steps — coating with photoresist, etching intricate layers, and wiring microscopic transistors — with polishing being a critical step that flattens and smooths the disc to exacting tolerances.
According to the company, the new metrology system integrates directly into the polishing workflow, enabling real-time measurements both before and after the polishing stage. Live data is fed back into the control system, allowing immediate process adjustments.
Why it matters
The direct integration of measurement and polishing into a single workflow could materially improve wafer uniformity and reduce material waste, the company said, addressing inefficiencies common in traditional, siloed production lines. For China's domestic semiconductor supply chain, which remains heavily reliant on foreign suppliers for more complex manufacturing tools, advances in CMP and metrology represent meaningful steps toward self-sufficiency in upstream chip fabrication.
CMP equipment and precision metrology sit at the intersection of multiple export-control pressure points, making domestic capability in these areas strategically significant beyond their immediate commercial value.
The competitive backdrop
While China has made incremental gains in wafer polishing and adjacent tooling, the industry continues to depend on overseas suppliers — most notably ASML of the Netherlands — for high-end photolithography systems used in advanced node production. Analysts at firms including Bernstein and Soochow Securities have tracked the widening gap between domestic Chinese toolmakers and global leaders in lithography, even as companies like Hwatsing close ground in sub-segments such as CMP.
The six-inch wafer segment, while less cutting-edge than the 300mm wafers used in leading-edge logic chips, is critical for power semiconductors, optical components, and legacy-node devices — all areas where China is aggressively expanding capacity.
What's next
The shipment to a domestic optical silicon materials producer suggests Hwatsing is targeting the materials supply chain as its first commercial beachhead for the new system. Broader adoption across wafer fabrication facilities would depend on the system's performance data from this initial deployment. Investors and industry observers will be watching whether Hwatsing extends the metrology platform to larger-diameter wafers — particularly 300mm — where the commercial and strategic stakes are considerably higher.
