Product Description

A chemical mechanical polishing slurry / slurry formulation developed for the semiconductor industry and for lithium tantalate / lithium niobate crystal wafer processing, suitable for high-efficiency planarization in precision and ultra-precision applications of LiTaO₃ / LiNbO₃. It is designed to improve the material removal rate of lithium tantalate (LiTaO₃) and lithium niobate (LiNbO₃) wafers, reduce surface roughness, and achieve an ultra-smooth surface.

产品特点

A “two-component” polishing slurry suitable for lithium tantalate (LT) and lithium niobate (LN) substrates.
The polishing slurry JZ-4904 demonstrates excellent performance under high-pressure and high-speed CMP conditions, with the following features:

Achieves higher removal rates and better planarization in a shorter time.
Suitable not only for composite substrates but also for single substrates.
Excellent particle removal, resulting in extremely low particle count after CMP, eliminating the need for additional RCA cleaning.
