RASIRC Granted New Patent for Removal of Ashable Hard Mask via a Hydrogen Peroxide Plasma Etch Process

March 6, 2025

RASIRC has been granted a new patent for the removal of ashable hard masks via a hydrogen peroxide plasma etch process, marking a significant advancement in plasma technology. OES data with BRUTE® Peroxide shows H₂O₂ plasma produces 10x more hydroxyl radicals than O₂ and H₂O plasmas, enabling gentler, more selective etching that enhances precision and reduces contamination in semiconductor manufacturing.
