Abstract

本发明公开了一种在硅衬底上制备高质量铟镓铝氮材料的方法,它首先在硅衬底表面形成一金属钛过渡层,然后在金属钛过渡层上形成铟镓铝氮叠层。所述铟镓铝氮叠层中包含至少一个氮化铝低温缓冲层,且该氮化铝低温缓冲层直接生长于钛过渡层上。本发明通过使用金属钛作为过渡层,可以防止硅衬底氮化形成不利于铟镓铝氮材料生长的氮化硅和金属镓的回熔,生长出高质量的铟镓铝氮材料。

Description

在硅衬底上制备铟镓铝氮材料的方法
技术领域
本发明涉及半导体材料,尤其是涉及一种在硅衬底上制备高质量铟镓铝氮材料的方法。
背景技术:
铟镓铝氮(InxGayAl1+x-yN,0<=x<=1,0<=y<=1)是制备短波长发光器件的优选材料体系。近年来已经用铟镓铝氮材料制造出许多新颖的发光器件,如蓝色、绿色、白色发光二极管,紫色半导体激光器等等。同时铟镓铝氮材料也是制备许多高性能电子器件的良好材料。现有技术中,在蓝宝石衬底和碳化硅衬底上制备铟镓铝氮材料的方法已经较为成熟。根据这些公开的技术,已经可以制备出高质量的铟镓铝氮材料。但是,碳化硅衬底非常昂贵,用于生长铟镓铝氮材料将使成本很高。而蓝宝石衬底也比较贵,而且它是绝缘体且加工困难,不能制成具有上下电极的芯片结构,这样就导致器件制造工艺复杂,成本增加。硅是一种最成熟的半导体材料,它不仅价格便宜,而且容易控制其导电类型和电阻率,其加工工艺也很成熟,如果用于生长铟镓铝氮将可以大大节约成本。然而在硅衬底上生长铟镓铝氮存在着许多困难,其中开始生长时硅衬底表面被氮化形成氮化硅和生长过程中镓金属回熔对获得高质量的铟镓铝氮影响很大。在已经公开的技术中,一般采用在硅衬底上沉积一层金属铝层来阻止氮化硅的形成和镓回熔。但是由于铝的熔点较低(660℃),而铟镓铝氮材料的生长温度很高(>1000℃),这一铝过渡层在铟镓铝氮材料的生长过程中不稳定,因此将不利于获得高质量的铟镓铝氮材料。
发明内容:
本发明的目的在于提供一种通过在硅衬底上形成一层金属钛过渡层来有效地阻止氮化硅的形成和防止镓回熔、从而利于获得高质量铟镓铝氮材料的方法。
本发明的目的是这样实现的:
1、在硅衬底表面形成一金属钛过渡层;
2、在金属钛过渡层上形成铟镓铝氮叠层。
所述钛过渡层的厚度范围为2-50,优选为5-20。
所述铟镓铝氮叠层中包含至少一个氮化铝低温缓冲层,且该氮化铝低温缓冲层直接生长于钛过渡层上。
本发明是通过在硅衬底上形成一层金属钛过渡层来有效地阻止氮化硅的形成和防止镓回熔,从而利于获得高质量铟镓铝氮材料。由于钛为六方密堆结构,与铟镓铝氮材料具有较好的匹配,而且其熔点高于1400℃,因此在铟镓铝氮生长过程中很稳定,可以有效地阻止氮化硅的形成和防止镓回熔。该金属钛过渡层厚度不能太厚也不能太薄,太薄了不能有效的保护硅表面不被氮化和阻止镓回熔,太厚了钛层表面不能维持长程有序,难以得到高的晶体质量。钛过渡层的厚度范围为2-50,优选为5-20。钛层的形成方法可以是气相沉积、真空蒸发、磁控溅射,以及其它常见的镀膜方法。该过渡层可以是预先形成然后放入铟镓铝氮材料生长室中,也可以在铟镓铝氮材料生长室中在线形成。在形成钛过渡层后,在其上生长铟镓铝氮材料,可以采用已经公开的任何公开技术,如化学气相沉积,分子束外延,卤化物气相外延等等。为了获得高的晶体质量,一般还需要采用二步法生长,即先生长一层氮化铝低温缓冲层,然后再升高温度生长外延层和器件制造所需要的微结构。为了进一步阻止镓的回熔,低温缓冲层优选为氮化铝层。
附图说明:
图1是本发明的剖面结构示意图。
具体实施方式:

把一个硅(111)衬底1清洗干净,放入一金属有机化学气相沉积设备的反应室,首先在1100℃用氢气对衬底1表面进行5分钟处理,接着在800℃下沉积30的金属钛过渡层和200的氮化铝低温缓冲层3,然后再升高温度到1050℃依次生长氮化镓掺硅层和氮化镓掺镁层4,氮化铝低温缓冲层3及氮化镓掺硅层和氮化镓掺镁层4构成铟镓铝氮叠层。
实施例2:
把一个硅(111)衬底1清洗干净,放入电子束蒸发台中正蒸镀10的钛金属膜即钛过渡层2,然后把蒸有钛过渡层2的衬底1放入一金属有机化学气相沉积设备的反应室,首先在1100℃用氢气对衬底1表面进行5分钟处理,接着在800℃下生长200的氮化铝低温缓冲层3,然后再升高温度到1030℃依次生长未掺杂氮化镓层、掺硅氮化镓层、铟镓氮/氮化镓多量子阱层、氮化镓掺镁层4,氮化铝低温缓冲层3及未掺杂氮化镓层、掺硅氮化镓层、铟镓氮/氮化镓多量子阱层、氮化镓掺镁层4构成铟镓铝氮叠层。
