FAQ<\/span><\/h2>\nQ1 : \u00c0 quoi sert une plaquette de saphir ?
Il est utilis\u00e9 comme substrat brut pour les semi-conducteurs, les diodes \u00e9lectroluminescentes, les applications optiques et les applications de recherche apr\u00e8s un traitement ult\u00e9rieur.<\/p>\n
Q2 : Quelle est la diff\u00e9rence avec une plaquette de saphir polie ?
Une plaquette vierge n'est pas polie et conserve des surfaces d\u00e9coup\u00e9es \u00e0 la scie, tandis qu'une plaquette polie est pr\u00eate pour la fabrication directe de dispositifs.<\/p>\n
Q3 : Les dimensions peuvent-elles \u00eatre personnalis\u00e9es ?
Oui, le diam\u00e8tre, l'\u00e9paisseur, l'orientation et la finition des bords peuvent \u00eatre personnalis\u00e9s en fonction des exigences techniques.<\/p>\n
Q4 : Est-il adapt\u00e9 \u00e0 la production directe de LED ?
Non. Il doit subir un rodage et un polissage avant d'\u00eatre utilis\u00e9 pour la croissance \u00e9pitaxiale des LED.<\/p>\n
Q5 : Qu'est-ce qui rend le saphir meilleur que le verre ou le quartz ?
Le saphir offre une duret\u00e9, une r\u00e9sistance \u00e0 la temp\u00e9rature et une stabilit\u00e9 chimique nettement sup\u00e9rieures \u00e0 celles des mat\u00e9riaux optiques conventionnels.<\/p>\n

Les plaquettes de saphir sont des substrats d'oxyde d'aluminium monocristallin (Al\u2082O\u2083) de haute puret\u00e9, tels qu'ils sont coup\u00e9s, d\u00e9riv\u00e9s directement de boules de saphir \u00e0 l'aide d'une technologie de sciage \u00e0 fil avanc\u00e9e. Contrairement aux plaquettes finies, ces substrats sont livr\u00e9s \u00e0 l'\u00e9tat brut et non trait\u00e9, ce qui signifie que la surface conserve les marques de scie et n'a pas subi de rodage, de polissage ou de planarisation chimico-m\u00e9canique (CMP).<\/p>\n![\"\u00c9bauches](\"https:\/\/www.zmsh-semitech.com\/wp-content\/uploads\/2026\/04\/sapphire_wafer_blank_high_purity_raw_sapphire_substrate_for_processing2-300x300.webp\")
