Description
技术领域
本发明属于半导体器件技术领域,具体涉及一种基于二维材料/氮化镓的双极型三极管及其制备方法。
背景技术
双极型晶体管(BJT)是利用电子和空穴两种载流子的开关半导体器件。通过注入少量的基区载流子,促使发射区发射出大量的少数载流子,从而产生电流放大的效果。双极型晶体管使用垂直的器件结构,电流可在垂直于整个器件平面的方向上流动,而非如金属-氧化物-半导体场效应晶体管(MOSFET)只能在最表面导通电流。因此,其特点是可以导通大电流和较大的电流增益特性。与单极晶体管相比,双极型晶体管可广泛用于大功率,大容量的电子系统中(例如用于太阳能发电的功率调节器,电动汽车和射频放大中)。而异质结双极型晶体管(HBT)具有较高的电流增益和截止频率,可广泛应用于各类射频电路中。
传统的异质结双极型晶体管基于硅/锗硅的异质结,利用硅/锗硅的价带能带差实现高增益,并使用超薄的锗外延层达到高截止频率的效果。然而,由于硅/锗硅的异质结双极型晶体管的禁带宽度较小,其击穿电压不高,难以应用于高功率的射频器件中。III族氮化物如氮化镓和铝镓氮,作为第三代半导体的代表性材料,具有大禁带宽度,高电子迁移率等特点,适合用于耐受高电压的功率器件中。基于氮化镓的场效应晶体管已经被大量研究。然而,由于氮化镓中较难获得P型掺杂,使得基于氮化镓的双极型晶体管的发展处于停滞状态。
发明内容
为了解决上述问题,本发明提供一种基于二维材料/氮化物的双极型三极管制备方法:包括如下步骤
提供一氮化镓基衬底1;
在所述氮化镓基衬底1上外延第一N型掺杂III族氮化物层2,定义所述第一N型掺杂III族氮化物层2为集电区;
在所述第一N型掺杂III族氮化物层上淀积P型掺杂二维材料层3,其中P型掺杂浓度为1018cm-3-1020cm-3,定义所述P型掺杂二维材料层3为基区;
在所述P型掺杂二维材料层3上淀积第二N型掺杂III族氮化物层4,刻蚀所述第二N型掺杂III族氮化物层4的端部暴露出所述P型掺杂二维材料层,定义暴露出的P型掺杂二维材料层为发射区;所述第一N型掺杂III族氮化物层2的掺杂浓度小于所述第二N型掺杂III族氮化物层4的掺杂浓度;
在所述第二N型III族氮化物层4上淀积金属形成发射极7,在暴露出的所述P型掺杂二维材料层3上淀积基极6,在所述第一N型III族氮化物层2底部沉积集电极5。
优选的,所述氮化镓基衬底1为均一材质的氮化镓衬底或氮化镓外延片。
优选的,所述氮化镓基衬底1为N型掺杂,掺杂浓度为1019cm-3-1021cm-3。
优选的,所述第一N型掺杂III族氮化物层2为弱N型掺杂,掺杂浓度为1015cm-3-1017cm-3。
优选的,淀积所述P型掺杂二维材料层3方式为薄膜转移工艺或化学气相淀积。
优选的,所述第二N型掺杂III族氮化物层4为重N型掺杂,掺杂浓度为1018cm-3-1021cm-3。
优选的,淀积所述第二N型掺杂III族氮化物层4方式为化学气相沉积或物理气相沉积;刻蚀所述第二N型掺杂III族氮化物层4方式为干法刻蚀,刻蚀气体为Cl2或BCl3。
优选的,淀积金属包括退火过程,退火时间为300℃-900℃。
优选的,所述第一N型掺杂III族氮化物层2和/或所述第二N型掺杂III族氮化物层4材料选自氮化镓、铝镓氮、铟镓氮、铝氮。
优选的,所述P型掺杂二维材料层3选自二硒化钨,二碲化钼、黑磷。
基于同样的发明构思,本发明还提供一种基于上述方法的双极型三极管晶体管,该三极管结构自下而上依次为氮化镓基衬底1,第一N型掺杂III族氮化物层2,P型掺杂二维材料层3、第二N型掺杂III族氮化物层4;所述第一N型掺杂III族氮化物层2为集电区;所述P型掺杂二维材料层3为基区;所述第二N型掺杂III族氮化物层3为发射区。
优选的,所述第一N型掺杂III族氮化物层2和/或所述第二N型掺杂III族氮化物层4厚度为100nm-10um。
优选的,所述P型二维材料层3的厚度为1nm-100nm。二维材料是近年来兴起的新型半导体材料,其具有可掺杂,禁带宽度和厚度灵活可调的优点。二维材料可通过控制材料生长和掺杂的方式形成N型掺杂或P型掺杂的掺杂。本发明将P型掺杂的二维材料和N型掺杂III族氮化物结合,以二维材料作为基区,氮化物作为发射区和集电区。由于P型掺杂二维材料和N型掺杂III族氮化物结合具有巨大的价带能量差,N型掺杂的III族氮化物结合的发射区向P型掺杂的二维材料的基区中发射电子的发射效率可得到大幅提升从而提高晶体管的电流增益。此外,由于二维材料的薄膜厚度具有灵活可控的特点,薄可至单原子层。使用超薄的二维材料作为基区,可大幅降低基区的载流子渡越时间,提升晶体管的截止频率。本半导体器件可广泛应用于射频功率放大,信号放大或混频等领域。即可作为分立器件单独使用,又可集成在单片集成系统中。

具体实施方式

在WSe2层上淀积一层重N型掺杂的AlGaN层,掺杂浓度为1019cm-3,淀积采用物理气相沉积方法。淀积后进行光刻并刻蚀从而定义出顶层的AlGaN层发射区,并露出下面的WSe2层。刻蚀采用干法刻蚀,刻蚀气体为BCl3。
淀积钛/铝/镍/金复合金属层并在800℃退火以形成基极、集电极和发射极。
铝镓氮相比于氮化镓具有更大的禁带宽度,因此可以耐受更高的工作电压,有利于形成高功率器件。
