(EN) POLISHING COMPOSITION AND METHOD FOR POLISHING SUBSTRATE USING THE COMPOSITION
(FR) COMPOSITION DE POLISSAGE ET PROCEDE DE POLISSAGE D'UN SUBSTRAT A L'AIDE DE LADITE COMPOSITION
Abrégé
(EN)
A polishing composition characterized in that the composition is boehmite-free and comprises water, abrasive grains, a polishing accelerator, and an organic acid ammonium salt or an inorganic acid ammonium salt. The polishing composition provides a high-quality polished surface without surface defects while a high polishing rate is maintained.
(FR)
Composition de polissage caractérisée en ce qu'elle est exempte de boehmite et contient de l'eau, des grains abrasifs, un accélérateur de polissage et un sel d'ammonium d'acide organique ou un sel d'ammonium d'acide inorganique. Ladite composition de polissage permet d'obtenir une surface polie de haute qualité exempte de défauts, tout en conservant une grande vitesse de polissage.
