Tuburile de cuar\u021b sunt utilizate \u00een mod obi\u0219nuit \u00een cuptoarele de difuzie la temperaturi ridicate pentru plachete semiconductoare pentru dopare (cum ar fi difuzia de fosfor sau bor) sau recoacere (activarea dopan\u021bilor).
Durata de via\u021b\u0103 a purt\u0103torilor este un parametru cheie pentru evaluarea calit\u0103\u021bii pl\u0103cilor de siliciu. Dac\u0103 impurit\u0103\u021bile tubului de cuar\u021b (cum ar fi ionii metalici) contamineaz\u0103 plachetele, aceasta poate duce la o recombinare crescut\u0103 a purt\u0103torilor \u0219i la o durat\u0103 de via\u021b\u0103 redus\u0103.
Testele implic\u0103 m\u0103surarea duratei de via\u021b\u0103 a purt\u0103torilor minoritari pentru a evalua impactul procesului asupra performan\u021bei electrice a plachetei.<\/p>\n\n\n\n

Tuburile de cuar\u021b sunt utilizate \u00een camerele de reac\u021bie CVD (Chemical Vapor Deposition). Dac\u0103 peretele tubului este contaminat sau sufer\u0103 devitrificare, calitatea stratului epitaxial poate fi afectat\u0103, ceea ce duce la reducerea duratei de via\u021b\u0103 a purt\u0103torilor.<\/p>\n\n\n\n

2. Testarea celulelor fotovoltaice (solare)<\/h3>\n\n\n\n
\u00cen procesele de celule solare de \u00eenalt\u0103 eficien\u021b\u0103, cum ar fi PERC \u0219i TOPCon, tuburile de cuar\u021b sunt utilizate pentru depunerea stratului de pasivare (cum ar fi SiNx sau Al\u2082O\u2083) sau arderea la temperaturi ridicate.
Durata de via\u021b\u0103 a purt\u0103torului afecteaz\u0103 \u00een mod direct eficien\u021ba de conversie a celulei. Dac\u0103 tubul de cuar\u021b introduce contaminare, rata de recombinare a suprafe\u021bei pl\u0103cii va cre\u0219te.
M\u0103sur\u0103torile sunt efectuate utiliz\u00e2nd QSSPC (fotoconductan\u021ba \u00een stare cvasi-steady) sau \u03bc-PCD (dec\u0103derea fotoconductan\u021bei cu microunde) pentru a determina durata de via\u021b\u0103 a purt\u0103torilor minoritari.<\/p>\n\n\n\n
\n\n\n\n3. Cercetarea materialelor (de exemplu, semiconductori cu band\u0103 larg\u0103)<\/h3>\n\n\n\n
Procesele la temperaturi ridicate (>1500\u00b0C) pentru dispozitivele din carbur\u0103 de siliciu (SiC) sau nitrur\u0103 de galiu (GaN) necesit\u0103 tuburi de cuar\u021b ultrapuri. Impurit\u0103\u021bile pot cre\u0219te densitatea st\u0103rilor de interfa\u021b\u0103, duc\u00e2nd la sc\u0103derea duratei de via\u021b\u0103 a purt\u0103torilor.
Cercetarea se concentreaz\u0103 adesea pe propriet\u0103\u021bile electrice ale straturilor epitaxiale sau ale straturilor de oxid.<\/p>\n\n\n\n
\n\n\n\n4. Alte teste conexe<\/h3>\n\n\n\n
Durata de via\u021b\u0103 a purt\u0103torului afecteaz\u0103 viteza de r\u0103spuns. Dac\u0103 tuburile de cuar\u021b contamineaz\u0103 materiale sensibile (cum ar fi InGaAs), performan\u021ba dispozitivului se poate deteriora.<\/p>\n\n\n\n
Unii clien\u021bi pot folosi pur \u0219i simplu tuburi de cuar\u021b ca vase de reac\u021bie pentru a testa dinamica purt\u0103torilor de noi materiale (cum ar fi perovskitele).<\/p>\n\n\n\n

Experimentele chimice generale au cerin\u021be de puritate relativ sc\u0103zute pentru tuburile de cuar\u021b, \u00een timp ce procesele semiconductoare\/fotovoltaice sunt extrem de sensibile la contaminare.<\/p>","protected":false},"excerpt":{"rendered":"
