Les tubes en quartz sont couramment utilis\u00e9s dans les fours de diffusion \u00e0 haute temp\u00e9rature des plaquettes de semi-conducteurs pour le dopage (comme la diffusion du phosphore ou du bore) ou le recuit (activation des dopants).
La dur\u00e9e de vie des porteurs est un param\u00e8tre cl\u00e9 pour \u00e9valuer la qualit\u00e9 des plaquettes de silicium. Si des impuret\u00e9s du tube de quartz (telles que des ions m\u00e9talliques) contaminent les plaquettes, cela peut entra\u00eener une augmentation de la recombinaison des porteurs et une r\u00e9duction de la dur\u00e9e de vie.
Les tests consistent \u00e0 mesurer la dur\u00e9e de vie des porteurs minoritaires afin d'\u00e9valuer l'impact du processus sur les performances \u00e9lectriques de la plaquette.<\/p>\n\n\n\n

Les tubes en quartz sont utilis\u00e9s dans les chambres de r\u00e9action CVD (Chemical Vapor Deposition). Si la paroi du tube est contamin\u00e9e ou subit une d\u00e9vitrification, la qualit\u00e9 de la couche \u00e9pitaxiale peut \u00eatre affect\u00e9e, ce qui entra\u00eene une r\u00e9duction de la dur\u00e9e de vie des porteurs.<\/p>\n\n\n\n

2. Essais de cellules photovolta\u00efques (cellules solaires)<\/h3>\n\n\n\n
Dans les proc\u00e9d\u00e9s de fabrication de cellules solaires \u00e0 haut rendement, tels que PERC et TOPCon, les tubes de quartz sont utilis\u00e9s pour le d\u00e9p\u00f4t de couches de passivation (telles que SiNx ou Al\u2082O\u2083) ou pour la cuisson \u00e0 haute temp\u00e9rature.
La dur\u00e9e de vie des porteurs affecte directement l'efficacit\u00e9 de conversion de la cellule. Si le tube de quartz introduit une contamination, le taux de recombinaison de la surface de la plaquette augmentera.
Les mesures sont effectu\u00e9es \u00e0 l'aide de la QSSPC (Quasi-Steady-State Photoconductance) ou de la \u03bc-PCD (Microwave Photoconductance Decay) pour d\u00e9terminer la dur\u00e9e de vie des porteurs minoritaires.<\/p>\n\n\n\n
\n\n\n\n3. Recherche sur les mat\u00e9riaux (par exemple, semi-conducteurs \u00e0 large bande passante)<\/h3>\n\n\n\n
Les processus \u00e0 haute temp\u00e9rature (>1500\u00b0C) pour les dispositifs en carbure de silicium (SiC) ou en nitrure de gallium (GaN) n\u00e9cessitent des tubes de quartz ultra-purs. Les impuret\u00e9s peuvent augmenter la densit\u00e9 des \u00e9tats d'interface, ce qui entra\u00eene une diminution de la dur\u00e9e de vie des porteurs.
La recherche se concentre souvent sur les propri\u00e9t\u00e9s \u00e9lectriques des couches \u00e9pitaxi\u00e9es ou des couches d'oxyde.<\/p>\n\n\n\n
\n\n\n\n4. Autres tests connexes<\/h3>\n\n\n\n
La dur\u00e9e de vie des porteurs affecte la vitesse de r\u00e9ponse. Si les tubes de quartz contaminent des mat\u00e9riaux sensibles (tels que l'InGaAs), les performances de l'appareil peuvent se d\u00e9t\u00e9riorer.<\/p>\n\n\n\n
Certains clients peuvent simplement utiliser des tubes de quartz comme r\u00e9cipients de r\u00e9action pour tester la dynamique des porteurs de nouveaux mat\u00e9riaux (tels que les p\u00e9rovskites).<\/p>\n\n\n\n
\n\n\n\nPertinence du test<\/h3>\n\n\n\n
Ce param\u00e8tre est essentiel dans les domaines des semi-conducteurs et de la photovolta\u00efque, alors que les exp\u00e9riences industrielles ou chimiques typiques ne le mesurent g\u00e9n\u00e9ralement pas de mani\u00e8re sp\u00e9cifique.<\/p>\n\n\n\n
Les exp\u00e9riences chimiques g\u00e9n\u00e9rales ont des exigences de puret\u00e9 relativement faibles pour les tubes de quartz, alors que les processus semi-conducteurs\/photovolta\u00efques sont extr\u00eamement sensibles \u00e0 la contamination.<\/p>","protected":false},"excerpt":{"rendered":"
