Ceramic chemical mechanical polishing (Ceramic CMP) is the core process to realize ultra-precision planarization of high-performance structural ceramics and functional ceramics. It is also an indispensable fundamental process for third-generation semiconductors, high-frequency communication, microelectronic packaging, and high-end aerospace manufacturing.

The current industry shows an overall development trend of upgrading demand, process iteration and accelerated domestic substitution. Traditional lapping and polishing can no longer meet the requirements of nanometer-level flatness and ultra-low surface roughness for high-end ceramic substrates, ceramic filters, aluminum nitride, silicon carbide ceramics and other devices. Ceramic CMP has gradually become the mainstream standard process in the industry.

Traditional processes are still adopted in China’s mid-to-low-end ceramic processing segments. In high-end fields, technical barriers still exist in dedicated polishing slurry, polishing pads, process matching models and global uniformity control. The core process system has long been restricted by overseas technologies, leaving huge room for domestic substitution.

The industry will present four major development trends in the future. First, ultra-precision extreme evolution. Oriented to wide-bandgap semiconductors and high-frequency components, the process evolves toward sub-nanometer surface accuracy, low damage and low stress, meeting the defect-free polishing demands of high-hardness and high-brittleness ceramic materials.

Second, process intellectualization. Relying on on-line topography detection, parameter closed-loop regulation and big data process modeling, it realizes adaptive control of the polishing process, stabilizes yield and reduces consumable costs.

Third, green and low-carbon development. Environment-friendly fluorine-free polishing slurry, waste liquid recycling and reusable polishing pads have become key R&D focuses, conforming to the green transformation direction of precision manufacturing.

Fourth, generalized application scenarios. The application expands gradually from electronic ceramics to medical ceramics, optical ceramics and new energy structural ceramics. Customized CMP processes compatible with multiple materials have become a research hotspot in the industry.

Overall, ceramic CMP has entered a stage of simultaneous technological breakthrough and scenario expansion. Benefiting continuously from the upgrading of high-end manufacturing industry, it will become an important growth track in the field of ultra-precision machining. Ceramic CMP Polisher is the key core equipment supporting the industrial development.
