Q : Quelle est l'\u00e9paisseur standard d'une plaquette de quartz de 8 pouces ?<\/strong>
A :<\/strong> L'\u00e9paisseur standard est de 0,5 \u00e0 1,0 mm, avec des options personnalis\u00e9es allant jusqu'\u00e0 10 mm pour les applications sp\u00e9cialis\u00e9es dans les semi-conducteurs et l'optique.<\/p>\n<\/li>\n- \n
Q : Pourquoi choisir des plaquettes de quartz fondu plut\u00f4t que des plaquettes de silicium ?<\/strong>
A :<\/strong> Les plaquettes de quartz fondu offrent une transparence sup\u00e9rieure aux UV, une plus grande stabilit\u00e9 thermique (jusqu'\u00e0 1730\u00b0C), une r\u00e9sistance chimique et une stabilit\u00e9 dimensionnelle, ce qui les rend id\u00e9ales pour la lithographie de haute pr\u00e9cision et les processus difficiles.<\/p>\n<\/li>\n- \n
Q : FUYAO peut-il fournir des formes de plaquettes et des traitements de surface personnalis\u00e9s ?<\/strong>
A :<\/strong> Oui. Les options comprennent des plaquettes rondes, carr\u00e9es, annulaires, en forme de secteur, avec des traitements de surface tels que le polissage optique, les rev\u00eatements AR\/IR\/DLC, le per\u00e7age et le rainurage.<\/p>\n<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"La plaquette de quartz fondu de 8 pouces est un substrat de quartz synth\u00e9tique de haute puret\u00e9 (SiO\u2082 \u226599,99%) con\u00e7u pour des applications de haute pr\u00e9cision dans les syst\u00e8mes semi-conducteurs, MEMS, optiques et laser.
