Description

互补金属氧化物半导体器件及其制备方法
本发明要求2015年12月22日递交的发明名称为“互补金属氧化物半导体器件及其制备方法”的申请号201510970419.4的在先申请优先权,上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及半导体领域,尤其涉及一种互补金属氧化物半导体器件及其制备方法。
背景技术
互补金属氧化物半导体(Complementary Metal Oxide Semiconductor,COMS)器件由P型沟通金属氧化物半导体(P-channel Metal Oxide Semiconductor,PMOS)以及N型沟道金属氧化物半导体(N-channel Metal Oxide Semiconductor,NMOS)共同构成,CMOS器件是液晶显示装置(Liquid Crystal Display,LCD)中驱动芯片的最基本的电路结构。在传统的LCD中,驱动芯片和基板(比如,玻璃基板)是没有集成的分离式设计,这使得LCD的制造成本较高且难以实现轻薄化设计。若能将驱动芯片直接做在基板上,这对于LCD等显示装置而言,无疑是一个非常大的进步。目前,一般采用低温多晶硅(Low Temperature Poly-silicon,LTPS)技术将COMS器件制备到基板上,相较于驱动芯片和基板分离设计有了一定的进步。然而,LTPS技术分别制备CMOS器件中PMOS和NMOS的半导体层,其制备工艺中包括激光退火、掺杂、粒子注入等相对复杂的工艺流程,因此成本较高。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
请一并参阅图1,图2及图3,图1为本发明一较佳实施方式的互补金属氧化物半导体器件的电路结构示意图;图2为图1中互补金属氧化物半导体器件的电路版图;图3为图2中沿I-I线的剖面结构示意图。所述互补金属氧化 物半导体(Complementary Metal Oxide Semiconductor,COMS)器件1包括基板110,所述基板110包括相对设置的第一表面110a及第二表面110b;设置在所述第一表面110a中部的第一金属层120;设置在所述第一金属层120及未覆盖所述第一金属层120的所述第一表面110a的绝缘层130;设置在所述绝缘层130上且对应所述第一金属层120设置的第一类型金属氧化物半导体层140;分别间隔设置在所述绝缘层130上的第一金属部151、第二金属部152及第三金属部153,所述第一金属部151及所述第二金属部152间隔设置在所述第一类型金属氧化物半导体层140两侧且均与所述第一类型金属氧化物半导体层140接触,所述第二金属部152设置在所述第一金属部151及所述第三金属部153之间,其中,所述第一金属部151、所述第二金属部152及所述第三金属部153定义为第二金属层150;第二类型有机半导体层160,所述第二类型有机半导体层160设置在所述第二金属部152与所述第三金属部153之间的间隙154,以及邻近所述间隙154的第二金属部152及所述第三金属部153上;钝化层170,设置在所述第一金属部151、所述第二金属部152、所述第三金属部153、所述第一金属部151与所述第二金属部152之间的第一类型金属氧化物半导体层140、以及所述第二类型有机半导体层160上;第三金属层180,设置在所述钝化层170上且对应所述第二类型有机半导体层160设置。
在本实施方式中,所述第一类型金属氧化物半导体层140为N型金属氧化物半导体层,所述第二类型有机半导体层160为P型有机半导体层。可以理解地,在另一实施方式中,所述第一类型金属氧化物半导体层140为P型金属氧化物半导体层,所述第二类型有机半导体层160为N型有机半导体层。所述当所述第一类型金属氧化物半导体层140为N型金属氧化物半导体层时,第一类型金属氧化物半导体层140为铟镓锌氧化物((Indium Gallium Zinc Oxide,IGZO)或者为铟锡锌氧化物(Indium Tin Zinc Oxide,ITZO)。
下面以所述第一类型金属氧化物半导体层140为N型金属氧化物半导体层,所述第二类型有机半导体层160为P型有机半导体层为例进行介绍。此时,包含所述第一类型金属氧化物半导体层140的为N型沟道金属氧化物半导体(N-channel Metal Oxide Semiconductor,NMOS),包含所述第二类型有机半导体层160的为P型沟通金属氧化物半导体(P-channel Metal Oxide Semiconductor, PMOS),即在图3中,位于虚线左侧的为NMOS,位于虚线右侧的为PMOS。所述第一金属层120为NMOS的栅极,位于所述第一金属层120上的绝缘层120为所述NMOS的栅极绝缘层,所述第一金属部151为NMOS的源极,位于虚线左侧的第二金属部152为NMOS的漏极。而,位于虚线右侧的绝缘层120构成PMOS的缓冲层,此时,所述NMOS的栅极绝缘层与PMOS的缓冲层共用同一层,位于虚线右侧的第二金属部152为PMOS的源极,由于所述第二金属部152为一整体,因此,NMOS的漏极与PMOS的源极共用。所述第三金属部153构成PMOS的漏极,所述第二类型有机半导体层160为PMOS的沟道层,位于所述第二类型有机半导体层160上的钝化层170构成所述PMOS的栅极绝缘层,此时,所述NMOS的钝化层与PMOS的栅极绝缘层共用同一层。所述第三金属层180构成PMOS的栅极。
在本实施方式中以CMOS的各个层结构直接或者间接设置在所述第一表面100a上为例进行描述,可以理解地,在其他实施方式中,CMOS的各个层结构也可以之间或者间接地设置在所述第二表面100b上。
请参阅图4,图4为图3中沿I-I线的另一较佳实施方式的剖面结构示意图。在本实施方式中,所述CMOS器件1还包括第一蚀刻阻挡层191,所述第一蚀刻阻挡层191上设置第一通孔191a,所述第一蚀刻阻挡层191设置在所述第一金属部151与所述第一类型金属氧化物半导体层140之间,所述第一金属部151通过所述第一通孔191a与所述第一类型金属氧化物半导体层140连接。所述CMOS器件还包括第二蚀刻阻挡层192,所述第二蚀刻阻挡层192上设置第二通孔192a,所述第二蚀刻阻挡层192设置在所述第二金属部152与所述第一类型金属氧化物半导体层140之间,所述第二金属部152通过所述第二通孔192a与所述第一类型金属氧化物半导体层140连接。所述第一蚀刻阻挡层191及所述第二蚀刻阻挡层191均用于保护所述第一类型金属氧化物半导体层140,以免在所述第二类型有机半导体层160形成的过程中的干蚀刻制程对所述第一类型金属氧化物半导体层140造成影响。
可以理解地,在一实施方式中,所述CMOS器件1中仅仅包括第一蚀刻阻挡层191,不包括第二蚀刻阻挡层192;或者在另一实施方式中,所述CMOS器件1仅仅包括第二蚀刻阻挡层192,不包括第一蚀刻阻挡层191。当所述 CMOS器件1中包括一个蚀刻阻挡层(第一蚀刻阻挡层191或者第二蚀刻阻挡层192)时,相较于不设置蚀刻阻挡层的CMOS器件而言,也能够起到保护所述第一类型金属氧化物半导体层140,以免在所述第二类型有机半导体层160形成的过程中的干蚀刻制程对所述第一类型金属氧化物半导体层140造成影响;当所述CMOS器件1中同时包含第一蚀刻阻挡层191及第二蚀刻阻挡层192时,能够更好地起到保护所述第一类型金属氧化物半导体层140,以免在所述第二类型有机半导体层160形成的过程中的干蚀刻制程对所述第一类型金属氧化物半导体层140造成影响。优选地,当所述CMOS器件1同时包含第一蚀刻阻挡层191及所述第二蚀刻阻挡层192时,所述第一蚀刻阻挡层191及所述第二蚀刻阻挡层192位于同一层,以便所述第一蚀刻阻挡层191及所述第二蚀刻阻挡层192的形成。
