Description

Product Overview
Designed for high-precision wafer thinning and polishing in semiconductor manufacturing. Its porous vitrified bond matrix reduces cutting resistance and friction heat, minimizing micro-cracks, subsurface damage, and wafer warping.
Key Applications
✓
Semiconductor Wafer Thinning
Back-grinding and surface thinning of silicon, SiC, and GaAs semiconductor wafers.
✓
Sapphire & Optical Windows
High-precision flattening and polishing of sapphire substrates and optical windows.
Why Choose Us (Advantages):
Minimal Subsurface Damage
Ultra-fine grain distribution prevents deep micro-cracks.
Low TTV (Total Thickness Variation)
Ensures uniform wafer thickness and high planarity.
Self-Sharpening Matrix
Maintains low, steady spindle power during high-speed thinning.
Stable Quality and Bulk Supply
Standard models available in stock; Approx. 7 Working Days to Dispatch.
