Os tubos de quartzo s\u00e3o normalmente utilizados em fornos de difus\u00e3o a alta temperatura de bolachas semicondutoras para dopagem (como a difus\u00e3o de f\u00f3sforo ou boro) ou recozimento (ativa\u00e7\u00e3o de dopantes).
O tempo de vida dos portadores \u00e9 um par\u00e2metro fundamental para avaliar a qualidade das bolachas de sil\u00edcio. Se as impurezas do tubo de quartzo (como i\u00f5es met\u00e1licos) contaminarem as bolachas, isso pode levar a um aumento da recombina\u00e7\u00e3o de portadores e a uma redu\u00e7\u00e3o do tempo de vida.
Os testes envolvem a medi\u00e7\u00e3o do tempo de vida dos portadores minorit\u00e1rios para avaliar o impacto do processo no desempenho el\u00e9trico da bolacha.<\/p>\n\n\n\n

Os tubos de quartzo s\u00e3o utilizados em c\u00e2maras de rea\u00e7\u00e3o CVD (Chemical Vapor Deposition). Se a parede do tubo ficar contaminada ou sofrer desvitrifica\u00e7\u00e3o, a qualidade da camada epitaxial pode ser afetada, resultando numa redu\u00e7\u00e3o do tempo de vida do portador.<\/p>\n\n\n\n

2. Ensaios de c\u00e9lulas solares fotovoltaicas<\/h3>\n\n\n\n
Nos processos de c\u00e9lulas solares de alta efici\u00eancia, como PERC e TOPCon, s\u00e3o utilizados tubos de quartzo para a deposi\u00e7\u00e3o da camada de passiva\u00e7\u00e3o (como SiNx ou Al\u2082O\u2083) ou para a queima a alta temperatura.
O tempo de vida do portador afecta diretamente a efici\u00eancia de convers\u00e3o da c\u00e9lula. Se o tubo de quartzo introduzir contamina\u00e7\u00e3o, a taxa de recombina\u00e7\u00e3o da superf\u00edcie da bolacha aumentar\u00e1.
As medi\u00e7\u00f5es s\u00e3o efectuadas utilizando QSSPC (fotocondut\u00e2ncia em estado quase estacion\u00e1rio) ou \u03bc-PCD (decaimento da fotocondut\u00e2ncia em micro-ondas) para determinar o tempo de vida dos portadores minorit\u00e1rios.<\/p>\n\n\n\n
\n\n\n\n3. Investiga\u00e7\u00e3o de materiais (por exemplo, semicondutores de grande abertura de banda)<\/h3>\n\n\n\n
Os processos a alta temperatura (>1500\u00b0C) para dispositivos de carboneto de sil\u00edcio (SiC) ou nitreto de g\u00e1lio (GaN) requerem tubos de quartzo ultra-puros. As impurezas podem aumentar a densidade do estado da interface, levando a uma diminui\u00e7\u00e3o do tempo de vida dos portadores.
A investiga\u00e7\u00e3o incide frequentemente nas propriedades el\u00e9ctricas das camadas epitaxiais ou das camadas de \u00f3xido.<\/p>\n\n\n\n
\n\n\n\n4. Outros testes relacionados<\/h3>\n\n\n\n
O tempo de vida dos portadores afecta a velocidade de resposta. Se os tubos de quartzo contaminarem materiais sens\u00edveis (como o InGaAs), o desempenho do dispositivo pode deteriorar-se.<\/p>\n\n\n\n
Alguns clientes podem simplesmente utilizar tubos de quartzo como recipientes de rea\u00e7\u00e3o para testar a din\u00e2mica de transporte de novos materiais (como perovskites).<\/p>\n\n\n\n

As experi\u00eancias qu\u00edmicas gerais t\u00eam requisitos de pureza relativamente baixos para os tubos de quartzo, enquanto os processos de semicondutores\/fotovoltaicos s\u00e3o extremamente sens\u00edveis \u00e0 contamina\u00e7\u00e3o.<\/p>","protected":false},"excerpt":{"rendered":"
