技术领域
本发明属于半导体材料生长技术领域,特别涉及一种在InP衬底上外延生长InGaAs的方法。
背景技术
InGaAs材料是由二元材料InAs和GaAs组成的,InAs与GaAs都是直接带隙半导体,且均为闪锌矿结构,组成的InGaAs材料也是直接带隙半导体,当In组分不同时,InGaAs材料的禁带宽度在0.35-1.43eV内变化。当InGaAs材料中的In组分为0.53时,InGaAs材料和InP衬底晶格匹配,禁带宽度为0.74eV。
InGaAs和其他材料相比有很多优点,以它作为吸收材料可以得到响应速度和运行速度非常快的探测器。由InGaAs材料制成的PIN探测器在光纤传输中发挥重要的作用,其较高的内量子效率和较低的暗电流,摒弃了以往需要制冷设备才能够在室温下连续工作的探测器,使得这类探测器有良好的发展前景。所以应用InGaAs材料作为吸收层的高速光电探测器得到了极大的发展,出现了一系列不同工作方式的光电探测器,包括InGaAs雪崩光电探测器(APD),InGaAs PIN光电探测器,InGaAs 金属-半导体-金属光电探测器(MSM-PD)。
因此,利用固态源分子束外延系统,如何外延得到高迁移率InGaAs材料,成为InGaAs器件材料外延的重点研究方向,对InGaAs光电器件和微电器件材料外延生产有重要的意义。

步骤4,在步骤3的预处理完成后,对InP衬底进行氧化膜的脱附,氧化膜的脱附时间根据t=-2.3h2+8.4h+2.2确定,其中t为氧化膜脱附时长,单位是min,h为步骤1得到的InP衬底氧化膜厚度,单位是nm;
步骤5,在步骤4中氧化膜的脱附完成之后,进行InP缓冲层外延;
步骤6,在步骤5中InP缓冲层外延完成之后,P阀门关闭,As阀门开至所需束流位置;
步骤7,在步骤6中P/As束流切换完成之后,进行InGaAs外延。

优选的,步骤4中使用P束流作为衬底保护气,将衬底加热器升温至衬底的RHEED图案出现×4再构条纹,此时温度为Tc,将Tc设置为基准温度。
优选的,步骤5中,氧化膜脱附完成之后,将衬底温度降为Tc以下30℃~50℃进行InP缓冲层外延。

(2)P/As束流的切换工艺可以有效地减少InP缓冲层与InGaAs材料之间四元合金界面的形成,减少杂质缺陷,降低InGaAs载流子浓度,提高材料迁移率。

附图标记说明:101、InP衬底;102、InP缓冲层;103、InGaAs外延层。
具体实施方式
以下结合实施例对本发明作进一步的描述,实施例仅用于对本发明进行说明,并不构成对权利要求范围的限制,本领域技术人员可以想到的其他替代手段,均在本发明权利要求范围内。
本发明提供一种在InP衬底上外延生长InGaAs的方法,包括以下步骤:
步骤1,测定InP衬底101的氧化膜厚度,可以使用椭圆偏振装置测定InP衬底101氧化膜厚度。
步骤2,测定Ga和In的生长速率,可以使用高能电子衍射仪装置进行测定。
步骤3,对InP衬底101进行预处理除气,预处理的温度为350~400℃,预处理时间为1~2h,其中升温和降温速率均为15 ~25℃/min。
步骤4,在步骤3的预处理完成后,对InP衬底101进行氧化膜的脱附,氧化膜的脱附时间根据t=-2.3h2+8.4h+2.2确定,其中t为氧化膜脱附时长,单位是min,h为步骤1得到的InP衬底氧化膜厚度,单位是nm;使用P束流作为衬底保护气,将衬底加热器升温至RHEED图案出现×4再构条纹,此时温度为Tc,将Tc设置为基准温度。
步骤5,在步骤4中氧化膜的脱附完成之后,将衬底温度降为Tc以下30℃~50℃进行InP缓冲层102外延,可以使用固态磷源裂解炉进行InP缓冲层102的外延,其中P与In束流的V/III比为5~20。

步骤7,在步骤6中P/As束流切换完成之后,进行InGaAs外延层103的生长,InGaAs的外延温度为Tc以下50℃~100℃,InGaAs的外延V/III比为10~25。
根据厚度测试值设定氧化膜脱附时长,避免传统方法中通过观察衬底表面再构带来的时长偏差,InP缓冲层生长完成后采用的P/As切换工艺,避免了InP缓冲层与InGaAs材料之间出现四元合金界面。工艺简单可重复,适合大批量生产。

步骤4,在步骤3的预处理完成后,对InP衬底进行氧化膜的脱附,氧化膜的脱附时间根据t=-2.3h2+8.4h+2.2确定,其中t为氧化膜脱附时长,单位是min,h为步骤1得到的InP衬底氧化膜厚度,单位是nm,得到氧化膜脱附时长为7.26min,使用P束流作为衬底保护气,将衬底加热器升温至RHEED图案出现×4再构条纹,此时温度为Tc,为580℃,将Tc设置为基准温度。

步骤6,在步骤5中InP缓冲层外延完成之后,P阀门以step的方式降低至0%,并维持30s,As阀门以2%/s的速度开至所需束流位置,并维持2min。
步骤7,在步骤6中P/As束流切换完成之后,进行InGaAs外延,InGaAs的外延温度为Tc以下50℃,即530℃,InGaAs的外延V/III比为17。
应说明的是,以上实施例仅用以说明本发明的技术方案而非限制,尽管参照较佳实施例对本发明进行了详细说明,本领域的普通技术人员应当理解,可以对本发明的技术方案进行修改或者等同替换,而不脱离本发明技术方案的精神和范围,其均应涵盖在本发明的权利要求范围当中。
