图1是示出根据本公开的一个实施方式的半导体装置的布局结构的图。
参照图1,多个晶体管区TR1和TR2在结构上可以基本彼此相同,从而将在下文中仅使用一个晶体管区TR1作为示例来描述以下实施方式。
晶体管区TR1可以实现为NMOS晶体管或PMOS晶体管,但不限于此。此外,晶体管区TR2可以实现为NMOS晶体管或PMOS晶体管,但不限于此。
第一方向(I)可以指垂直于第二方向(II)的方向。第三方向(III)可以指与在第一方向(I)和第二方向(II)上延伸的水平面垂直的方向。例如,第三方向(III)可以与第一方向(I)和第二方向(II)中的每一个垂直。
基板100可以包括例如诸如硅(Si)或锗(Ge)之类的半导体材料,或者诸如硅锗(SiGe)、碳化硅(SiC)、砷化镓(GaAs)、砷化铟(InAs)或磷化铟(InP)之类的化合物半导体材料。基板100可以包括导电区域,例如掺杂有杂质的阱或者掺杂有杂质的结构。
可以在基板100的指定区域中形成阱区110。在这种情况下,基板100可以掺杂有杂质以具有P型或N型导电材料。
为了便于描述,假设基板100实现为P型基板。在一些实施方式中,阱区110可以掺杂有杂质以具有P型或N型导电材料。为了便于描述,假设阱区110实现为N型阱。
阱区110可以包括多个有源区ACT1至ACT3。多个有源区ACT1至ACT3可以是用于接收晶体管区的源极电压、漏极电压和体电压的区域。
多个有源区ACT1至ACT3可以掺杂有杂质以具有P型或N型导电性。在一些实现方式中,多个有源区ACT1至ACT3中的每一个可以实现为掺杂有P型杂质的P型区域。根据各种电路类型的使用,多个有源区ACT1至ACT3可以被配置为具有不同的尺寸和不同的形状。
有源区ACT1可以位于晶体管TR1的中心区域。有源区ACT1可以形成为矩形岛状。
有源区ACT2和ACT3可以相对于晶体管TR1的中心区域形成在第二方向(II)的两侧。也就是说,有源区ACT2可以在第二方向(II)上位于有源区ACT1的一侧。有源区ACT3可以在第二方向(II)上位于有源区ACT1的另一侧。有源区ACT2和ACT3中的每一个可以形成为在第一方向(I)上延伸的线形状。有源区ACT2和有源区ACT3可以在第二方向(II)上彼此隔开预定距离。有源区ACT2和ACT3可以在第一方向(I)上具有相同或基本相同的长度。
此外,可以在基板100上形成多个虚设有源区DACT1至DACT6。多个虚设有源区DACT1至DACT6可以各自形成在形成于中心区域的有源区ACT1的外壁附近。例如,当沿第三方向观察时,多个虚设有源区DACT1至DACT6可以在第一方向和第二方向上围绕有源区ACT1而布置在基板100上。
在一些实施方式中,可以设置多个虚设有源区DACT1至DACT6以防止应力施加到有源区ACT1中的晶体管。例如,虚设有源区DACT1至DACT6可以形成在有源区ACT1附近并且与之相邻。
在半导体装置中,在半导体基板上形成的单元元件(例如,晶体管、二极管、电阻器等)必须彼此电隔离。因此,可以利用在所有半导体制造工序中使用的初始阶段工序来完成这种器件隔离工序。初始阶段工序能够极大地影响每个有源区的尺寸和后续工序的制造余量。
例如,浅沟槽隔离(STI)工艺可以解决由制造工序导致的不稳定性,诸如,由半导体装置的设计规则导致的场氧化膜的劣化。近来,为了进一步提高高度集成的半导体存储器装置的集成度,已经将半导体存储器装置发展为具有较小尺寸的组成元件。由于浅沟槽隔离(STI)工艺中的应力,具有较小元件的半导体存储器装置可能具有侧壁弱化的沟槽。为了解决这种可能性,所公开技术的实施方式中的半导体装置可以在半导体装置中包括多个虚设有源区DACT1至DACT6,以减少或防止受浅沟槽隔离(STI)工艺影响而在一个或更多个晶体管中产生应力。
多个虚设有源区DACT1至DACT6中的每一个可以形成为掺杂有P型杂质的P型区。尽管在本文公开的实施方式中,为了便于描述,多个虚设有源区DACT1至DACT6中的每一个形成为P型区,但是所公开的技术的范围或精神不限于此。在其它实施方式中,多个虚设有源区DACT1至DACT6也可以根据需要而利用其它类型的材料形成。
参照图1,多个虚设有源区DACT1至DACT6当中的虚设有源区DACT1和DACT2可以相对于中心区域设置在有源区ACT1的两侧。虚设有源区DACT1和DACT2中的每一个可以形成为在第二方向(II)上延伸的线形状。与有源区ACT1相比,虚设有源区DACT1和DACT2中的每一个可以形成为在第二方向(II)上具有更长的长度。例如,虚设有源区DACT1可以从有源区ACT1沿第一方向设置,使得虚设有源区DACT1的边缘或侧面覆盖有源区ACT1的相邻边缘或侧面,或者与有源区ACT1的相邻边缘或侧面完全交叠。类似地,在有源区ACT1的与虚设有源区DACT1相对的一侧,虚设有源区DACT2可以从有源区ACT1沿第一方向设置,使得虚设有源区DACT2的边缘或侧面覆盖有源区ACT1的相邻边缘或侧面,或者与有源区ACT1的相邻边缘或侧面完全交叠。虚设有源区DACT1和虚设有源区DACT2可以在第一方向(I)上彼此隔开预定距离。有源区ACT1可以设置在虚设有源区DACT1和虚设有源区DACT2之间。
有源区ACT1和有源区ACT2可以在第二方向(II)上彼此隔开预定距离。虚设有源区DACT3可以形成在有源区ACT1和有源区ACT2之间。换句话说,虚设有源区DACT3可以定位成与有源区ACT2邻接或相邻。虚设有源区DACT3可以沿第一方向(I)设置在虚设有源区DACT1和DACT2之间。虚设有源区DACT3可以形成为矩形或线形。虚设有源区DACT3可以在第一方向(I)上具有与有源区ACT1相同或基本相同的宽度。
有源区ACT1和有源区ACT3可以在第二方向(II)上彼此间隔开预定距离,并且有源区ACT3位于有源区ACT1的与有源区ACT2相对的另一侧。多个虚设有源区DACT4至DACT6可以形成在有源区ACT1和有源区ACT3之间。多个虚设有源区DACT4至DACT6中的每一个可以形成为矩形或线形。
多个虚设有源区DACT4至DACT6可以分别从多个虚设有源区DACT1至DACT3的侧面(例如,下侧)沿第二方向(II)设置。多个虚设有源区DACT4至DACT6中的每一个可以与有源区ACT3邻接或相邻。虚设有源区DACT4至DACT6可以在第一方向(I)上彼此隔开,并且可以间隔开预定距离。
栅极(G)可以设置在有源区ACT1和虚设有源区DACT5上方。晶体管TR1和TR2可以通过各自具有其相应的栅极来彼此区分。
栅极(G)可以形成为在第二方向(II)上延伸,并且可以形成为角形或锤形。例如,锤形的把手可以在第二方向(II)上延伸,而栅极(G)的区域(A)对应于锤形的头部并且在第一方向(I)上突出或延伸。换句话说,栅极(G)可以在第二方向(II)上延伸,并且可以形成为栅极(G)的区域(A)在第一方向(I)上弯曲的L形结构。栅极(G)的区域(A)可以设置为与虚设有源区DAC5交叠。在这种情况下,栅极(G)的区域(A)可以被形成为向每个晶体管提供电压。
栅极(G)的区域(A)可以通过栅极硅通孔(GTV)电联接到虚设有源区DACT5。也就是说,栅极(G)的区域(A)和虚设有源区(DACT5)可以在第三方向(III)上设置在同一条线上。
栅极(G)的区域(A)和虚设有源区DACT5可以关于第一方向(I)和第二方向(II)中的每一个而具有相同的尺寸或者可以具有不同的尺寸。在一些实施方式中,栅极(G)的区域(A)可以关于第一方向(I)和第二方向(II)中的每一个而在尺寸上小于虚设有源区DACT5。
尽管将栅极(G)设置为在有源区ACT1的顶面处或顶面附近横穿有源区ACT1,但是栅极(G)可以不设置在晶体管TR1的外围区域中,诸如其中设置有虚设有源区DACT4和DACT6的区域中。因此,在任何特定区域中不存在栅极图案的情况下,图案密度存在差异,从而可能导致在曝光和蚀刻步骤中不均匀地实现栅极图案。
因此,可以形成虚设栅极DG,使得通过设置虚设栅极DG,能够减小栅极图案之间的分隔距离的任何差异。通过实现虚设栅极DG,栅极图案能够以距离相同或基本相同的、更均匀的间隔彼此隔开。在图1中,从第三方向观察,虚设栅极DG可以设置为与虚设有源区DACT1至DACT6的一些边缘相邻。虚设栅极DG可以形成为围绕虚设有源区DACT1和DACT2。虚设栅极DG可以形成为在第二方向(II)上横穿虚设有源区DACT3的中心区域。
栅极(G)的侧面或边缘可以在第一方向(I)上与虚设栅极(DG)隔开预定距离。虚设栅极DG的分段可以具有与区域(A)外部的栅极(G)基本相同或相同的宽度(例如,第一方向I的宽度)。
可以在有源区ACT1至ACT3上方形成多个金属接触件(M0C)。多个金属接触件(M0C)可以在有源区ACT2和ACT3的顶面处或顶面附近沿第一方向(I)彼此隔开预定距离。多个金属接触件(M0C)可以在有源区(ACT1)的顶面处或顶面附近沿第一方向(I)和第二方向(II)形成为晶格或栅格形状。
如上所述,可以在虚设有源区DACT5上方形成栅极硅通孔(GTV)。栅极硅通孔(GTV)可以电联接到栅极(G)的区域(A)。此外,栅极硅通孔(GTV)可以在穿过栅极(G)之后电联接到下虚设有源区DACT5。
此外,可以在基板100上方形成多个金属层(M0)。金属层(M0)中的每一个可以形成为在第二方向(II)上延伸的线形状。多个金属层(M0)可以形成为在第二方向(II)上具有不同的长度,并且可以相对于彼此交错。多个金属层(M0)可以在第一方向(I)上彼此隔开预定距离。多个金属层(M0)可以通过金属接触件(M0C)电联接到有源区ACT1至ACT3。
金属层(M0_1)可以设置在金属层(M0)的延长线上。金属层(M0_1)可以形成为在第二方向(II)上延伸的线形状。金属层(M0_1)可以通过栅极硅通孔(GTV)电联接到栅极(G)和虚设有源区DACT5。金属层(M0_1)可以将晶体管区TR1的栅极硅通孔(GTV)电联接到晶体管区TR2的栅极硅通孔(GTV)。也就是说,晶体管区TR1的栅极(G)锤区域(A)可以通过金属层(M0_1)电联接到晶体管区TR2的栅极(G)锤区域(A)。
多个金属层(M0)当中的金属层M2可以在第一方向(I)上与金属层(M0_1)隔开预定距离。金属层M2可以形成为在第二方向(II)上延伸的线形状。金属层(M2)可以将晶体管区TR1的有源区ACT1电联接到晶体管区TR2的有源区ACT1。
可以在金属层(M0)上方形成多个金属接触件(M1C)。多个金属接触件(M1C)可以在第一方向(I)上彼此隔开预定距离。
此外,可以在金属层(M0)上方形成多个金属层(M1)。每个金属层(M1)可以形成为在第一方向(I)上延伸的线形状。金属层(M1)可以通过金属接触件(M1C)电联接到有源区ACT1。
图2是示出根据本公开的一个实施方式的沿着图1所示的线Y-Y’截取的图1所示半导体装置的示例的截面图。
参照图2,可以在基板100中或基板100上形成阱区110。在这种情况下,基板100可以实现为掺杂有P型杂质的P型基板。
阱区110可以包括晶体管的有源区ACT1和虚设有源区DACT5。在这种情况下,有源区ACT1和虚设有源区DACT5中的每一个可形成为掺杂有P型杂质的P型区域。
晶体管的栅极(G)的区域(A)可以在第三方向(III)上形成在虚设有源区DACT5上方。栅极(G)可以形成在层间绝缘膜120中或层间绝缘膜120上。层间绝缘膜120可以形成为诸如氧化膜的绝缘层。栅极(G)可以通过栅极硅通孔(GTV)电联接到下虚设有源区DACT5。
在一些实施方式中,虚设有源区DACT5可以形成在栅极(G)下方,即,虚设有源区DACT5可以在第二方向(II)上偏离栅极(G)。在该示例中,如果虚设有源区DACT5在第三方向(III)上没有形成在栅极(G)下方,而是虚设有源区DACT5与栅极(G)的侧面隔开,则由线Y-Y’示出的横截面的宽度可以增加,以便包括虚设有源区DACT5。因此,在图2中,设置在栅极(G)下方的虚设有源区DACT5沿相同的垂直线形成,并且减小或消除了将有源区ACT1和虚设有源区DACT5分离的任何距离。线Y-Y’的较短宽度可以对应于设置在半导体装置中的较小或较窄区域中的器件隔离结构。
金属接触件(M0C)中的每一个可以形成在有源区ACT1的顶面和金属层(M0)的底面之间。栅极硅通孔(GTV)可以在穿过栅极(G)的同时形成在金属层(M0_1)的底面和虚设有源区DACT5的顶面之间。栅极硅通孔(GTV)可以使上金属层(M0_1)、下栅极(G)和虚设有源区DACT5彼此电联接。
在一些实施方式中,栅极(G)和虚设有源区DACT5可以通过栅极硅通孔(GTV)彼此电联接。结果,能够防止在需要保护器件隔离沟槽的侧壁的后续等离子体注入工艺中发生等离子体诱导损伤(PID)。
也就是说,栅极硅通孔(GTV)和电联接到栅极(G)的虚设有源区DACT5可以用作能够防止等离子体诱导损伤(PID)的二极管图案。结果,可以防止半导体装置的组成元件的电特性劣化。更具体地,可以认为晶体管的阈值电压的偏移是这种电特性劣化的一个示例。
此外,金属层(M0)和金属层(M0_1)可以关于第三方向(III)形成在相同层中,并且可以在第二方向(II)上彼此隔开预定距离。金属接触件(M1C)可以形成在金属层(M0)的顶面和金属层(M1)的底面之间。金属层(M1)可以形成在金属层(M0)上方。金属层(M1)可以通过金属接触件(M1C)电联接到金属层(M0)。
图3A至图3D是示出根据本公开的实施方式的沿着图1所示的线Y-Y’截取的半导体装置的制造工序的示例的截面图。图4A至图4D是示出根据本公开的实施方式的沿着图1所示的线X-X’截取的半导体装置的制造工序的示例的截面图。在图3A至图3D和图4A至图4D中,为了便于描述,本文将省略与图2的组成元件相同的一些组成元件。
参照图3A和图4A,可以执行杂质注入工序来调整基板100中的掺杂密度,从而形成阱区110。在这种情况下,阱区110可以用作装置(例如,晶体管)的主体。
可以在阱区110中形成晶体管的有源区ACT1和虚设有源区DACT5。在这种情况下,可以通过浅沟槽隔离(STI)、硅局部氧化(LOCOS)处理等形成有源区ACT1和虚设有源区DACT5。
此外,可以在虚设有源区DACT5上方形成晶体管的栅极(G)。也就是说,栅极(G)可以沿垂直方向或第三方向(III)形成在虚设有源区DACT5上方。在虚设有源区DACT5上方形成氧化膜(未示出)和导线之后,可以响应于对应晶体管的栅极长度而对导线进行蚀刻,从而形成栅极(G)的图案。栅极(G)可以对应于要联接到上金属线和下金属线(未示出)的锤区域(A)。
在这种情况下,栅极(G)可以由各种导电材料形成。例如,栅极(G)可以由选自金属、金属和多晶硅以及多晶硅中的任何一种形成。在一些实施方式中,栅极(G)可以由金属和多晶硅形成。
此后,如图3B和图4B所示,可以对沿垂直方向形成在虚设有源区DACT5上方的栅极(G)进行蚀刻,从而形成接触孔H1。在这种情况下,可以对接触孔H1进行蚀刻以使虚设有源区DACT5的顶面暴露。
随后,如图3C和图4C所示,可以在栅极(G)结构的整个表面上方沉积层间绝缘膜120。在这种情况下,层间绝缘膜120可以包括氮化物膜或氧化物膜。
可以蚀刻层间绝缘膜120以形成接触孔H2。在这种情况下,可以蚀刻接触孔H2以使有源区ACT1的顶面暴露。因此,下有源区ACT1与用于连接虚设有源区DACT5和上金属线的接触件可以彼此电隔离。当对层间绝缘膜120进行蚀刻时,可以打开或重新打开栅极(G)的孔H1。
此后,如图3D和图4D所示,接触孔H1和H2可以利用接触插塞材料掩埋,从而能够形成金属接触件(M0C)和栅极硅通孔(GTV)。因此,栅极硅通孔(GTV)、栅极(G)和虚设有源区DACT5可以彼此物理接触。在这种情况下,埋入在接触孔H1中以形成栅极硅通孔(GTV)的材料可以与埋入在接触孔H2中以形成金属接触件(M0C)的材料相同。
在一些实施方式中,为了改进电特性,可以用特定材料附加掩埋其中接触孔H1与栅极(G)和虚设有源区DACT5接触的边界区域。
掩埋在其中接触孔H1与栅极(G)和虚设有源区DACT5接触的边界区域中的特定材料应当电联接到栅极(G)和虚设有源区DACT5,使得特定材料可以由导电材料形成。在这种情况下,导电材料可以包括诸如钨(W)、钛(Ti)和氮化钛(TiN)之类的金属材料,可以包括多晶硅,或者可以包括金属和多晶硅。
此后,可以在金属接触件(M0C)上方沉积金属层(M0),并且可以在栅极硅通孔(GTV)上方沉积金属层(M0_1)。
图5是示出根据本公开的一个实施方式的半导体装置的布局结构的示例的图。图6是示出根据本公开的一个实施方式的沿着图5所示的线C-C’截取的半导体装置的示例的截面图。在图5和图6中,用相同的附图标记表示与图1和图2中组成元件相同的组成元件,因此为了便于描述,这里将省略其详细描述。
参照图5和图6,晶体管区TR1和晶体管TR2可以在沿第一方向(I)跨过其间的线上彼此对称。也就是说,晶体管区TR1和晶体管区TR2可以布置成彼此面对,同时相对于第一方向(I)具有镜像对称结构。
在图6中,晶体管区TR1的栅极硅通孔(GTV)和晶体管区TR2的栅极硅通孔(GTV)可以通过金属层(M0_1)彼此电联接。也就是说,晶体管区TR1的栅极(G)、晶体管区TR2的栅极(G)以及每个晶体管的虚设有源区DACT5可以通过金属层(M0_1)彼此电联接。
从以上描述显而易见,基于所公开技术的实施方式的半导体装置可以改进至少一个晶体管的应力,并且可以减小将被占据的区域的整体尺寸。
所公开技术的实施方式可以提供能够通过上述专利文献直接或间接地识别的各种效果。
本领域的技术人员应当理解,在不脱离本公开的精神和本质特征的情况下,可以以除了本文阐述的方式之外的其它特定方式来实现实施方式。因此,上述实施方式在所有方面都应被解释为例示性而非限制性的。本公开的范围应当由所附权利要求及其法律等同物来确定,而不是由以上描述来确定。此外,在所附权利要求的含义和等效范围内的所有变化都被认为包含在本申请中。此外,本领域技术人员应当理解,在所附权利要求中没有彼此明确引用的权利要求可以作为实施方式而组合呈现,或者在提交申请后通过后续修改而被包括为新的权利要求。
尽管已经描述了多个例示性实施方式,但是应当理解,本领域技术人员能够设计出将落入本公开的原理的精神和范围内的许多其它变型和实施方式。具体地说,可以对本公开、附图和所附权利要求的范围内的组成部分和/或布置进行多种更改和变型。除了组成部分和/或布置的更改和变型之外,替代使用对于本领域技术人员来说也是显而易见的。
