F: Was ist die Standarddicke eines 8-Zoll-Quarzwafers?<\/strong>
A:<\/strong> Die Standarddicke betr\u00e4gt 0,5-1,0 mm, wobei f\u00fcr spezielle Halbleiter- und optische Anwendungen kundenspezifische Optionen bis zu 10 mm m\u00f6glich sind.<\/p>\n<\/li>\n- \n
F: Warum sollte man sich f\u00fcr Quarzglaswafer und nicht f\u00fcr Siliziumwafer entscheiden?<\/strong>
A:<\/strong> Wafer aus Quarzglas bieten eine hervorragende UV-Transparenz, h\u00f6here thermische Stabilit\u00e4t (bis zu 1730 \u00b0C), chemische Best\u00e4ndigkeit und Dimensionsstabilit\u00e4t und sind damit ideal f\u00fcr die Hochpr\u00e4zisionslithografie und raue Prozesse.<\/p>\n<\/li>\n- \n
F: Kann FUYAO kundenspezifische Waferformen und Oberfl\u00e4chenbehandlungen anbieten?<\/strong>
A:<\/strong> Ja. Zu den Optionen geh\u00f6ren runde, quadratische, ringf\u00f6rmige und sektorf\u00f6rmige Wafer mit Oberfl\u00e4chenbehandlungen wie optisches Polieren, AR\/IR\/DLC-Beschichtungen, Bohren und Rillenschneiden.<\/p>\n<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"Der 8-Zoll-Wafer aus Quarzglas ist ein hochwertiges, hochreines Substrat aus synthetischem Quarz (SiO\u2082 \u226599,99%), das f\u00fcr hochpr\u00e4zise Anwendungen in der Halbleiter-, MEMS-, Optik- und Lasertechnik entwickelt wurde.
