Kvartsr\u00f8r bruges ofte i h\u00f8jtemperaturdiffusionsovne til halvlederskiver til doping (f.eks. fosfor- eller bordiffusion) eller udgl\u00f8dning (aktivering af dopingstoffer).
B\u00e6rernes levetid er en n\u00f8gleparameter til evaluering af siliciumskivernes kvalitet. Hvis urenheder fra kvartsr\u00f8ret (f.eks. metalioner) forurener waferne, kan det f\u00f8re til \u00f8get rekombination af b\u00e6rere og reduceret levetid.
Testene omfatter m\u00e5ling af minoritetsb\u00e6rerens levetid for at evaluere processens indvirkning p\u00e5 waferens elektriske ydeevne.<\/p>\n\n\n\n

Kvartsr\u00f8r bruges i CVD-reaktionskamre (Chemical Vapor Deposition). Hvis r\u00f8rv\u00e6ggen bliver forurenet eller oplever devitrifikation, kan kvaliteten af det epitaksiale lag blive p\u00e5virket, hvilket resulterer i reduceret levetid for b\u00e6reren.<\/p>\n\n\n\n

2. Test af fotovoltaik (solceller)<\/h3>\n\n\n\n
I h\u00f8jeffektive solcelleprocesser som PERC og TOPCon bruges kvartsr\u00f8r til aflejring af passiveringslag (som SiNx eller Al\u2082O\u2083) eller h\u00f8jtemperaturbr\u00e6nding.
B\u00e6rernes levetid p\u00e5virker direkte cellens konverteringseffektivitet. Hvis kvartsr\u00f8ret introducerer forurening, vil waferens rekombinationshastighed p\u00e5 overfladen stige.
M\u00e5linger udf\u00f8res ved hj\u00e6lp af QSSPC (Quasi-Steady-State Photoconductance) eller \u03bc-PCD (Microwave Photoconductance Decay) for at bestemme minoritetsb\u00e6rerens levetid.<\/p>\n\n\n\n
\n\n\n\n3. Materialeforskning (f.eks. halvledere med bredt b\u00e5ndgab)<\/h3>\n\n\n\n
H\u00f8jtemperaturprocesser (>1500 \u00b0C) for siliciumcarbid- (SiC) eller galliumnitrid- (GaN) enheder kr\u00e6ver ultrarene kvartsr\u00f8r. Urenheder kan \u00f8ge gr\u00e6nsefladens tilstandst\u00e6thed, hvilket f\u00f8rer til nedsat levetid for b\u00e6rere.
Forskningen fokuserer ofte p\u00e5 de elektriske egenskaber af epitaksiale lag eller oxidlag.<\/p>\n\n\n\n
\n\n\n\n4. Andre relaterede tests<\/h3>\n\n\n\n
B\u00e6rernes levetid p\u00e5virker reaktionshastigheden. Hvis kvartsr\u00f8r forurener f\u00f8lsomme materialer (som f.eks. InGaAs), kan enhedens ydeevne forringes.<\/p>\n\n\n\n
Nogle kunder bruger m\u00e5ske blot kvartsr\u00f8r som reaktionsbeholdere til at teste b\u00e6rerdynamikken i nye materialer (som f.eks. perovskitter).<\/p>\n\n\n\n
\n\n\n\nTestens relevans<\/h3>\n\n\n\n
Denne parameter er kritisk inden for halvleder- og solcelleomr\u00e5det, mens typiske industrielle eller kemiske eksperimenter generelt ikke m\u00e5ler den specifikt.<\/p>\n\n\n\n
Generelle kemiske eksperimenter har relativt lave krav til renheden af kvartsr\u00f8r, mens halvleder- og solcelleprocesser er ekstremt f\u00f8lsomme over for forurening.<\/p>","protected":false},"excerpt":{"rendered":"
