P: \u00bfCu\u00e1l es el grosor est\u00e1ndar de una oblea de cuarzo de 8 pulgadas?<\/strong>
A:<\/strong> El grosor est\u00e1ndar es de 0,5-1,0 mm, con opciones personalizadas de hasta 10 mm para aplicaciones \u00f3pticas y de semiconductores especializadas.<\/p>\n<\/li>\n- \n
P: \u00bfPor qu\u00e9 elegir obleas de cuarzo fundido en lugar de obleas de silicio?<\/strong>
A:<\/strong> Las obleas de cuarzo fundido ofrecen una transparencia UV superior, una mayor estabilidad t\u00e9rmica (hasta 1730 \u00b0C), resistencia qu\u00edmica y estabilidad dimensional, lo que las hace ideales para litograf\u00eda de alta precisi\u00f3n y procesos duros.<\/p>\n<\/li>\n- \n
P: \u00bfPuede FUYAO proporcionar formas de oblea y tratamientos de superficie personalizados?<\/strong>
A:<\/strong> S\u00ed.
