Welche hochreinen Quarzprodukte werden in Prozessen f\u00fcr integrierte Schaltkreise verwendet? Welche Anforderungen gibt es an den Gehalt an Verunreinigungen?<\/p>\n\n\n\n
Zu den hochreinen Quarzprodukten, die h\u00e4ufig in integrierten Schaltkreisen verwendet werden, geh\u00f6ren Quarzwafer, Quarzkristalle, Quarzrohre und Quarzfenster.<\/p>\n\n\n\n
Bei Quarzwafern muss der Gehalt an Verunreinigungen extrem niedrig sein, im Allgemeinen im Bereich von Teilen pro Milliarde (ppb) oder darunter. Dies liegt daran, dass die Wafer w\u00e4hrend des Herstellungsprozesses hohen Temperaturen, Dr\u00fccken, starken S\u00e4uren, starken Basen und anderen Bedingungen ausgesetzt sind und Verunreinigungen die elektrischen Eigenschaften und die Zuverl\u00e4ssigkeit der Wafer beeintr\u00e4chtigen k\u00f6nnen.<\/p>\n\n\n\n
Bei Quarzkristallen muss auch der Gehalt an Verunreinigungen so niedrig wie m\u00f6glich gehalten werden, in der Regel im ppb-Bereich. Quarzkristalle werden zur Herstellung von Komponenten wie Oszillatoren und Filtern verwendet, und Verunreinigungen k\u00f6nnen ihre Frequenzstabilit\u00e4t und Leistung beeintr\u00e4chtigen.<\/p>\n\n\n\n
Bei Quarzrohren und Quarzfenstern muss der Gehalt an Verunreinigungen relativ niedrig sein, im Allgemeinen im Bereich von Teilen pro Million (ppm). Quarzrohre und -fenster werden f\u00fcr die Herstellung von Vakuumger\u00e4ten und optischen Vorrichtungen verwendet, und Verunreinigungen k\u00f6nnen ihre physikalischen und optischen Eigenschaften beeintr\u00e4chtigen.<\/p>\n\n\n\n
Zusammenfassend l\u00e4sst sich sagen, dass die Anforderungen an den Gehalt an Verunreinigungen f\u00fcr hochreine Quarzprodukte, die in Prozessen f\u00fcr integrierte Schaltungen verwendet werden, sehr streng sind und Verunreinigungen minimiert werden m\u00fcssen, um ihre Auswirkungen auf die Leistung der Ger\u00e4te zu verringern.<\/p>","protected":false},"excerpt":{"rendered":"
