AI Technical Summary

Technical Problem

Existing CMP technologies struggle to achieve high grinding rates for carbon films on semiconductor substrates.

Method used

A grinding composition comprising abrasive particles, preferably anionic modified colloidal silicon dioxide, and a nonionic surfactant, such as polyoxyethylene glycol compounds, enhances the grinding rate of carbon films by increasing contact frequency and improving surface interaction.

Benefits of technology

The composition achieves a high grinding rate of carbon films, exceeding 80 Å/min, effectively addressing the limitations of previous technologies.
