Stealth Dicing™ process can be performed based on the wafer surface height, making it possible to reliably process wafers with significant warpage.
Wafer shape is measured using a high-resolution sensor to singulate at the optimal processing area.
High-quality processing can be achieved for sapphire, SiC, and GaAs using laser oscillators suited for each material.
DISCO is an alliance partner* of Hamamatsu Photonics, which owns the portfolio of patents for Stealth Dicing technology.
