Quarzrohre werden h\u00e4ufig in Hochtemperatur-Diffusions\u00f6fen f\u00fcr Halbleiterwafer zur Dotierung (z. B. Phosphor- oder Bor-Diffusion) oder zum Ausgl\u00fchen (Aktivierung von Dotierstoffen) verwendet.
Die Lebensdauer der Ladungstr\u00e4ger ist ein Schl\u00fcsselparameter f\u00fcr die Bewertung der Qualit\u00e4t von Siliziumwafern. Wenn Quarzrohrverunreinigungen (z. B. Metallionen) die Wafer verunreinigen, kann dies zu einer erh\u00f6hten Rekombination der Ladungstr\u00e4ger und einer verringerten Lebensdauer f\u00fchren.
Bei den Tests wird die Lebensdauer der Minorit\u00e4tstr\u00e4ger gemessen, um die Auswirkungen des Prozesses auf die elektrische Leistung des Wafers zu bewerten.<\/p>\n\n\n\n

Quarzglasrohre werden in CVD-Reaktionskammern (Chemical Vapor Deposition) verwendet. Wenn die R\u00f6hrenwand verunreinigt wird oder entglast, kann die Qualit\u00e4t der Epitaxieschicht beeintr\u00e4chtigt werden, was zu einer verringerten Lebensdauer der Ladungstr\u00e4ger f\u00fchrt.<\/p>\n\n\n\n

2. Photovoltaik (Solarzellen) Pr\u00fcfung<\/h3>\n\n\n\n
Bei hocheffizienten Solarzellenverfahren wie PERC und TOPCon werden Quarzrohre f\u00fcr die Abscheidung von Passivierungsschichten (wie SiNx oder Al\u2082O\u2083) oder das Hochtemperaturbrennen verwendet.
Die Lebensdauer der Ladungstr\u00e4ger wirkt sich direkt auf die Umwandlungseffizienz der Zelle aus. F\u00fchrt das Quarzrohr Verunreinigungen ein, erh\u00f6ht sich die Oberfl\u00e4chenrekombinationsrate des Wafers.
Die Messungen werden mit QSSPC (Quasi-Steady-State Photoconductance) oder \u03bc-PCD (Microwave Photoconductance Decay) durchgef\u00fchrt, um die Lebensdauer der Minorit\u00e4tstr\u00e4ger zu bestimmen.<\/p>\n\n\n\n
\n\n\n\n3. Materialforschung (z. B. Halbleiter mit breiter Bandl\u00fccke)<\/h3>\n\n\n\n
Hochtemperaturprozesse (>1500\u00b0C) f\u00fcr Bauteile aus Siliziumkarbid (SiC) oder Galliumnitrid (GaN) erfordern hochreine Quarzrohre. Verunreinigungen k\u00f6nnen die Grenzfl\u00e4chendichte erh\u00f6hen, was zu einer geringeren Lebensdauer der Ladungstr\u00e4ger f\u00fchrt.
Die Forschung konzentriert sich h\u00e4ufig auf die elektrischen Eigenschaften von Epitaxieschichten oder Oxidschichten.<\/p>\n\n\n\n
\n\n\n\n4. Andere verwandte Tests<\/h3>\n\n\n\n
Die Lebensdauer der Ladungstr\u00e4ger beeinflusst die Reaktionsgeschwindigkeit. Wenn Quarzrohre empfindliche Materialien (wie InGaAs) verunreinigen, kann sich die Leistung der Ger\u00e4te verschlechtern.<\/p>\n\n\n\n
Manche Kunden verwenden Quarzrohre einfach als Reaktionsgef\u00e4\u00dfe, um die Tr\u00e4gerdynamik neuer Materialien (z. B. Perowskite) zu testen.<\/p>\n\n\n\n
\n\n\n\nRelevanz des Tests<\/h3>\n\n\n\n
Dieser Parameter ist in den Bereichen Halbleiter und Photovoltaik von entscheidender Bedeutung, w\u00e4hrend er bei typischen industriellen oder chemischen Experimenten im Allgemeinen nicht speziell gemessen wird.<\/p>\n\n\n\n
Bei allgemeinen chemischen Experimenten sind die Anforderungen an die Reinheit von Quarzrohren relativ gering, w\u00e4hrend Halbleiter-\/Photovoltaikprozesse \u00e4u\u00dferst empfindlich auf Verunreinigungen reagieren.<\/p>","protected":false},"excerpt":{"rendered":"
