Description
技术领域
本揭露内容实施例是有关一种半导体装置和其制造方法,特别是关于一种具有多重栅极结构的半导体装置。
背景技术
电子产业正在面临对于更小及更快的电子装置的不断增长的需求,同时这些电子装置需要支援更多日益复杂和精密的功能。因此,半导体产业中存在制造低成本、高效能及低功率的集成电路(integrated circuits,ICs)的趋势。目前为止,很大程度上是透过缩小半导体集成电路的尺寸(例如将特征的尺寸最小化)来达成这些目标,从而提升生产效率及降低相关的成本。然而,这样的微缩半导体也为制造半导体的制程带来更多的复杂性。因此,为了使半导体集成电路和装置持续地进步,需要制造半导体的制程和技术也有类似的进步。
近来,半导体产业引进多重栅极装置,通过增加栅极-通道的连接、降低关闭状态(OFF-state)的电流且减少短通道效应(short-channel effects,SCEs)以提升对栅极的控制。
其中一种引进的多重栅极装置是环绕式栅极晶体管(gate-all aroundtransistor,GAA)。环绕式栅极装置因其栅极结构能环绕着通道区域延伸,提供两面或四面来接触通道而得名。环绕式栅极装置能和传统互补式金属氧化物半导体(complementarymetal-oxide-semiconductor,CMOS)的制程相容,而且环绕式栅极装置的结构允许其更加地缩小,同时维持栅极的控制能力及减轻短通道效应。尽管现有制造环绕式栅极装置的方法通常能够满足它们预期的目的,但在各方面都尚未完全令人满意。例如,在维持对栅极的控制能力以及减轻短通道效应上仍然存在挑战。
发明内容
根据本揭露内容的多个实施方式,是提供一种装置,包含第一晶体管及第二晶体管。第一晶体管具有第一导电类型,配置于半导体基板上。第一晶体管包含第一磊晶层、第二磊晶层、第一栅极介电层及第一金属栅极层。第一磊晶层由第一半导体材料组成。第二磊晶层由第一半导体材料组成且配置于第一磊晶层上方。第一栅极介电层环绕第一磊晶层和第二磊晶层且从第一磊晶层的顶面延伸至第二磊晶层的底面,第一磊晶层的顶面背对半导体基板且第二磊晶层的底面面对半导体基板。第一金属栅极层环绕第一栅极介电层,第一栅极介电层包含第一磊晶层和第二磊晶层。第二晶体管具有第二导电类型,配置于半导体基板上,第二导电类型和第一导电类型相反。第二晶体管包含第三磊晶层、第四磊晶层、第二栅极介电层及第二金属栅极层。第三磊晶层由第一半导体材料组成。第四磊晶层由第二半导体材料组成且直接配置于第三磊晶层上方,第二半导体材料不同于第一半导体材料。第二栅极介电层配置于第三磊晶层和第四磊晶层上方。第二金属栅极层配置于第二栅极介电层上方。

图1为制造半导体的方法100,方法100包含制造多重栅极装置。多重栅极装置是指具有至少一些栅极材料配置于此装置的至少一通道的多个面上的装置(例如半导体晶体管)。在某些实施例中,多重栅极装置可为环绕式栅极装置,此环绕式栅极装置具有栅极材料配置于此装置的至少一通道的至少四个面上。环绕式栅极装置中的通道区域可为“纳米线”,纳米线包含各种几何形状(例如圆柱、条状)和各种尺寸的通道区域。
图2至图17B为根据图1的方法100的各种阶段的半导体装置200的实施方式的等角视图。图18A至图19C为根据图1的方法100的各种阶段的半导体装置200的实施方式剖面示意图,分别对应至上述的等角视图。如同此处讨论的其他方法的实施方式和例示性的装置,可使用CMOS技术流程制造部分的半导体装置200,因此某些制程仅在此简述。此外,例示性的半导体装置可包含各种其他装置及特征,例如其他类型的装置,如附加晶体管(additional transistors)、双载子接面晶体管(bipolar junction transistors)、电阻、电容、电感元件、二极管、保险丝、静态随机存取记忆体(static random access memory,SRAM)或/及其他逻辑电路等,但为了对本揭露内容的发明性概念有更佳的了解,这些都被简化。在某些实施方式中,例示性的装置包含多个半导体装置(例如晶体管),半导体装置包含可相互连接的P型场效晶体管(P-type field-effect transistor,PFETs)、N型场效晶体管(N-type field-effect transistors,NFETs)等。此外,需要注意的是方法100的制程步骤包含任何参照附图的叙述,连同本揭露内容提供的其他方法和例示性的图式,都仅为例示性且不意欲超出所附专利范围具体的内容。
请参照图1及图2,方法100起始于步骤102,使用抗击穿(anti-punchthrough,APT)布植222至基板210。在目前的实施方式中,基于装置效能的考量,基板210包含第一区域212及分离的第二区域214。在某些实施方式中,第一区域212可包含N型场效晶体管区域而且第二区域214可包含P型场效晶体管区域。为了简化,如图所示,在揭露方法内容的图2-8中,绘示的方法100都执行于第一区域212和第二区域214。
在某些实施方式中,基板210可为半导体基板,例如硅基板。基板210可包含各种层,包含形成于半导体基板的导电层或绝缘层。基板210可包含各种掺杂型态,取决于设计上的需求。举例来说,不同的掺杂分布(例如n型井、p型井)可形成于基板210上及依不同装置类型设计的区域(例如N型场效晶体管(NFET)、P型场效晶体管(PFET))中。适当的掺杂可包含掺质的离子布植或/及扩散制程。基板210基本上具有隔离特征(例如浅沟槽隔离(shallow trench isolation,STI)特征)插入于提供不同装置类型的区域之间。基板210也可包含其他半导体,例如锗、碳化硅、锗化硅或钻石。可替代地,基板210可包含化合物半导体或/及合金半导体。此外,基板210可选择性地包含磊晶层(epitaxial layer,epi-layer),可为了增强效能而施加应变于磊晶层;基板210也可包含绝缘层上覆硅(silicon-on-insulator,SOI)结构、或/及其他适当的强化特征。
举例来说,可执行抗击穿布植222于装置的通道区的底下区域,避免击穿或非期望的扩散。在某些实施方式中,执行第一微影制程(photolithography)步骤以图案化P型的抗击穿区域(P-type APT region)及执行第二微影制程步骤以图案化N型的抗击穿区域(N-type APT region)。举例来说,在某些实施方式中,执行第一微影制程步骤包含形成光阻层(光阻)于基板210上方,曝光光阻形成图案(例如P型抗击穿布植遮罩),执行后曝光(post-exposure)烘烤制程,并且将光阻显影以形成图案化的光阻层。举例而言,经由离子布植制程布植P型掺质形成P型的抗击穿区域,P型掺质可包含硼、铝、镓、铟、或/及其他P型受体(acceptor)材料。之后,在某些实施方式中,可执行第二微影制程步骤,其中第二微影制程步骤可包含形成光阻层(光阻)于基板210上方,曝光光阻形成图案(例如N型抗击穿布植遮罩),执行后曝光烘烤制程,并且将光阻显影以形成图案化的光阻层。举例而言,经由离子布植制程布植N型掺质形成N型的抗击穿区域,N型掺质可包含砷、磷、锑、或/及其他N型施体(donor)材料。此外,在各种实施方式中,抗击穿布植制程可具有高掺质浓度,举例来说,掺质浓度介于1x1018cm-3至1x1019cm-3之间。在某些实施方式中,如下文所述,可有利地使用这样的高抗击穿掺质浓度,因为隔离层后续形成于抗击穿布植基板的上方,可作为掺质扩散阻障层。
请参照图1和图3,方法100进行至步骤104,形成磊晶堆叠(epitaxial stack)310于抗击穿布植后的基板210的上方,包含在N型场效晶体管区域212及P型场效晶体管区域214中。磊晶堆叠310包含第一磊晶层314和第二磊晶层316,具有第一组成的第一磊晶层314被多个具有第二组成的第二磊晶层316插入。第一和第二组成可为不同或相同。在一实施方式中,第一磊晶层314由锗化硅组成,且第二磊晶层316由硅组成。然而,其他实施方式都是可能的,包含第一组成和第二组成具有不同的氧化率。在某些实施方式中,第一磊晶层314包含锗化硅且第二磊晶层316包含硅。
第二磊晶层316或其部分可形成多重栅极装置200的通道区域。举例而言,第二磊晶层316可称为“纳米线”,纳米线用于形成多重栅极装置200(例如环绕式栅极装置)的通道区域。这些“纳米线”也可用于形成多重栅极装置200的部分源极/漏极特征,如下文所述。下面会再讨论使用第二磊晶层316定义装置的一或多个通道。需要注意的是第二磊晶层316(纳米线)形成于N型场效晶体管212及P型场效晶体管214两者的上方,第二磊晶层提供了制造装置200的制程的简易性。
需要注意的是,图3绘示第一磊晶层314的六个层和第二磊晶层316的五个层。这仅为了说明且并非为了限制。可以理解的是可形成任何数量的磊晶层于磊晶堆叠310中,层的数量取决于所欲的用于装置200的通道区域的数量。在某些实施方式中,第二磊晶层316的数量介于2-10。在某些实施方式中,磊晶堆叠310最上面的磊晶层是第一磊晶层314。因此,第一磊晶层314的总数比第二磊晶层316的总数多一层。
以下将描述更细部的细节,在N型场效晶体管区域212中,各第二磊晶层316可作为后续的环绕式栅极装置的第一通道区域,且可基于装置效能的考量来选择第二磊晶层316的厚度。第一磊晶层314可用于定义后续的环绕式栅极装置的相邻第一通道区域的间隙距离,且可基于装置效能的考量来选择第一磊晶层314的厚度。此外,在P型场效晶体管区域214中,各第一磊晶层314可作为后续的栅极堆叠装置的第一通道区域,且可基于装置效能的考量来选择第一磊晶层314的厚度。第二磊晶层316可用于定义后续的栅极堆叠装置的相邻第二通道区域的距离,且可基于装置效能的考量来选择第二磊晶层316的厚度。在某些实施方式中,第二磊晶层316的厚度大于第一磊晶层314的厚度。举例来说,第二磊晶层316厚度和第一磊晶层314厚度的比值(第二磊晶层316厚度/第一磊晶层314厚度)介于1.1至2。在一实施方式中,第一磊晶层314的厚度介于约2-6nm而且第一磊晶层316的厚度介于3-11nm。第一磊晶层314和第二磊晶层316的厚度基本上是均匀的。
举例而言,可使用分子束磊晶制程(molecular beam epitaxial,MBE)、金属有机化学气相沉积(metalorganic chemical vapor deposition,MOCVD)制程、或/及其他适当的磊晶生长制程磊晶生长出磊晶堆叠310的层。在某些实施方式中,磊晶生长层可例如为第二磊晶层316,第二磊晶层316包含和基板210相同的材料。在某些实施方式中,第一磊晶生长层314和第二磊晶生长层316包含不同于基板210的材料。如同前文所述,至少在某些实施例中,第一磊晶层314包含磊晶生长锗化硅(SiGe)层而且第二磊晶层316包含磊晶生长硅(Si)层。可替代地,在某些实施方式中,第一磊晶生长层314和第二磊晶生长层316中任何一个可包含其他材料,例如锗、化合物半导体、合金半导体、或其组合;化合物半导体可例如为碳化硅、砷化镓、磷化镓、磷化铟、砷化铟、或/及锑化铟;合金半导体可例如为SiGe、GaAsP、AlInAs、AlGaAs、InGaAs、GaInP、或/及GaInAsP、或其组合。如前文所述,可基于不同的氧化程度、蚀刻选择比性质来选择第一磊晶生长层314和第二磊晶生长层316。在各种实施方式中,第一磊晶生长层314和第二磊晶生长层316中基本上是没有掺质(例如外质掺质浓度(extrinsic dopant concentration)介于约0cm-3至1x1017cm-3),举例来说,在磊晶生长制程中不刻意执行掺杂。
如图3的实施例所示,硬遮罩(hard mask,HM)层320可形成于磊晶堆叠310上方。在某些实施方式中,硬遮罩层320包含氧化层325(例如衬垫氧化层,衬垫氧化层可包含硅)及氮化层326(例如衬垫氮化层,衬垫氧化层可包含Si3N4)形成于氧化层325上方。在某些实施例中,硬遮罩层320包含热生长氧化层、化学气相沉积(chemical vapor deposition,CVD)所沉积的氧化物、或/及原子层沉积(atomic layer deposition,ALD)所沉积的氧化物。在某些实施方式中,硬遮罩层320包含使用化学气相沉积或其他适当的技术沉积的氮化层。硬遮罩层320可使用于保护部分的基板210或/及磊晶堆叠310或/及用于定义如下文所述的图案(例如鳍板元件)。
请参照图1及图4,方法100进行至步骤106,在N型场效晶体管区域212和P型场效晶体管区域214中,形成从基板210延伸出的鳍板元件410(也称为鳍板)。在各种实施方式中,各鳍板410包含从基板210形成的一部分基板、磊晶堆叠的部分各磊晶层,包含磊晶层314和磊晶层316、及硬遮罩层320的一部分。
可使用适当的制程制造鳍板410,包含微影及蚀刻制程。微影制程可包含形成光阻层于基板210上方(例如图3的硬遮罩层320上方),将光阻曝光形成图案,执行后曝光烘烤制程,以及将光阻显影以形成遮罩元件,遮罩元件包含光阻。在某些实施方式中,可使用电子束(electron beam,e-beam)微影制程执行图案化光阻以形成遮罩元件。之后遮罩元件可用于保护基板210的区域及形成于基板210上的层,同时蚀刻制程穿过硬遮罩层320及磊晶堆叠310至基板210中,形成沟槽414于未被保护的区域,进而留下多个延伸的鳍板410。可使用干式蚀刻(例如反应式离子蚀刻)、湿式蚀刻、或/及其组合蚀刻沟槽414。
可使用许多其他制造方法的实施方式在基板210上形成鳍板,包含,举例来说,定义鳍板区域(例如使用遮罩或隔离区域)并将磊晶堆叠310磊晶生长成鳍板410的形式。在某些实施方式中,形成鳍板410可包含减少鳍板410宽度的修整(trim process)制程。修整制程可包含湿式或/及干式蚀刻制程。
请参照图1和图5,方法100进行至步骤108,在N型场效晶体管区域212和P型场效晶体管区域214中形成浅沟槽隔离(shallow trench isolation,STI)特征510于鳍板410之间。举例来说,在某些实施方式中,先沉积介电层于基板210上方,使用介电材料填充沟槽414。在某些实施方式中,介电层可包含氧化硅、氮化硅、氮氧化硅、氟掺杂硅玻璃(fluorine-doped silicate glass,FSG)、低介电常数介电质、其组合、或/及其他适当的材料。在各种实施例中,可使用化学气相沉积(CVD)制程、次大气压化学气相沉积(subatmospheric CVD,SACVD)制程、可流动式化学气相沉积(flowable CVD)、原子层沉积(ALD)制程、物理气相沉积制程(physical vapor deposition,PVD)、或/及其他适当的制程沉积介电层。在某些实施方式中,举例来说,在沉积介电层之后,可将装置200退火以提升介电层的品质。在某些实施方式中,介电层(及后续形成的浅沟槽隔离特征510)可包含多层结构,举例来说,具有一或多个衬里层。
在形成浅沟槽隔离特征510中,在沉积介电层后,使用例如化学机械研磨(chemical mechanical polishing,CMP)制程将沉积的介电材料薄化及平坦化。化学机械研磨制程可平坦化介电层的顶面。在某些实施方式中,用于平坦化装置200的顶面的化学机械研磨制程也可用于从各鳍板410移除硬遮罩层320。在某些实施方式中,可替代地使用适当的蚀刻制程(例如干式或湿式蚀刻)执行移除硬遮罩层320。
请参照图1及图6,方法100进行至步骤110,在N型场效晶体管区域212和P型场效晶体管区域214中使浅沟槽隔离特征510凹陷成510’。浅沟槽隔离特征510’插入于鳍板410之间,使鳍板410延伸高于凹陷的浅沟槽隔离特征510’。在某些实施方式中,凹陷制程可包含干式蚀刻制程、湿式蚀刻制程、或/及其组合。在某些实施方式中,控制凹陷的深度(例如控制蚀刻时间)以曝露出鳍板410上部的所欲高度,称为410’。在某些实施方式中,鳍板410’包含磊晶堆叠310的各层。
请参照图1和图7,方法100进行至步骤112,在N型场效晶体管区域212和P型场效晶体管区域214中,形成虚设(dummy)介电层520于鳍板410’上方。在某些实施方式中,虚设介电层520可包含氧化硅、氮化硅、高介电常数介电材料、或/及其他适当的材料。在各种实施例中,可使用化学气相沉积(CVD)制程、次大气压化学气相沉积(subatmospheric CVD,SACVD)制程、可流动式化学气相沉积(flowable CVD)、原子层沉积(ALD)制程、物理气相沉积制程(physical vapor deposition,PVD)、或/及其他适当的制程沉积虚设介电层520。举例而言,虚设介电层520可用于避免后续的制程伤害鳍板410’(例如后续形成虚设栅极堆叠的过程)。
请参照图1和图8,方法100进行至步骤114,在N型场效晶体管区域212和P型场效晶体管区域214中形成栅极堆叠610。在一实施方式中,栅极堆叠610是虚设(牺牲)栅极堆叠而且将会被装置200后续制程阶段中的最终栅极堆叠取代。尤其是,如下文所述,虚设栅极堆叠610在之后的制程阶段中可被高介电常数(high K)介电层及金属栅极(metal gate)堆叠取代。在某些实施方式中,虚设栅极堆叠610形成于基板210上方而且至少部分配置于鳍板410’上方。虚设栅极堆叠610下方的鳍板410’的部分可称为通道区域620。虚拟栅极堆叠610也可定义鳍板410’的源极/漏极(S/D)区域630,例如,鳍板410’邻近通道区域620和鳍板410’相对侧的区域。
在某些实施方式中,虚设栅极堆叠610包含虚设介电层520、电极层614及栅极硬遮罩616,栅极硬遮罩616可包含多层618及619(例如氧化层618及氮化层619)。在某些实施方式中,虚设栅极堆叠610不包含虚设介电层520,例如,在沉积虚设栅极堆叠610前移除虚设介电层520。在某些实施方式中,栅极堆叠包含额外的虚设栅极介电层增加或取代虚设介电层520。在某些实施方式中,使用各种制程步骤形成虚设栅极堆叠610,例如层沉积、图案化、蚀刻及其他适当的制程步骤。例示性的层沉积制程包含化学气相沉积(包含低压化学气相沉积及等离子增强化学气相沉积)、物理气相沉积、原子层气相沉积、热氧化、电子束蒸镀(e-beam evaporation)、或其他适当的沉积技术、或其组合。举例说明形成栅极堆叠,图案化制程包含微影制程(例如光学微影或电子束微影),微影制程可还包含涂覆光阻(例如旋转涂覆)、软烤、光罩对准、曝光、后曝光烘烤、光阻显影、清洗、干燥(例如旋转干燥或/及硬烤)、其他适当的微影技术、或/及其组合。在某些实施方式中,蚀刻制程可包含干式蚀刻(例如反应式离子蚀刻)、湿式蚀刻、或/及其他蚀刻方式。
如前文所述,虚设栅极堆叠610可包含额外的栅极介电层。例如,虚设栅极堆叠610可包含氧化硅。可替代地或额外地,虚设栅极堆叠610的栅极介电层可包含氮化硅、高介电常数介电材料或其他适当的材料。在某些实施方式中,电极层614可包含多晶硅(polysilicon)。在某些实施方式中,栅极硬遮罩616包含氧化层618,例如衬垫氧化层,衬垫氧化层包含氧化硅。在某些实施方式中,栅极硬遮罩616包含氮化层619,例如衬垫氮化层,衬垫氮化层可包含Si3N4、氮氧化硅、或/及碳化硅。
再次参照图8,在某些实施方式中,在形成虚设栅极610之后,从基板210曝露的区域,包含未被虚设栅极610覆盖的鳍板410’,移除虚设介电层520。蚀刻制程可包含湿式蚀刻、干式蚀刻、或/及其组合。
如前文所述,揭露制造方式的第2-8图绘示在N型场效晶体管区域212和P型场效晶体管区域214上执行方法100。从图9A及以下图式开始,本揭露内容绘示分别在于N型场效晶体管区域212中形成装置200N及在P型场效晶体管区域214中形成装置214P的不同制程步骤。
参照第1、9A及9B图,方法100进行至步骤116,在N型场效晶体管区域212中的源极/漏极区域630中移除第一磊晶层314,同时用第一图案化硬遮罩730覆盖P型场效晶体管区域214。在某些实施方式中,在移除N型场效晶体管区域212中的第一磊晶层314之前,形成第一图案化硬遮罩730覆盖P型场效晶体管区域214。第一图案化硬遮罩730可包含使用微影制程形成的图案化光阻层。可替代地,可使用沉积硬遮罩层,再使用微影制程形成图案化光阻层于硬遮罩层上方,并透过图案化光阻层蚀刻硬遮罩材料层形成第一图案化硬遮罩730。
在目前的实施方式中,在形成图案化硬遮罩730后,从N型场效晶体管区域212中的源极/漏极区域630移除磊晶堆叠310的第一磊晶层314。为了清楚起见,在移除第一磊晶层314后,磊晶堆叠310称为310R。图9A绘示间隙810取代磊晶层314(绘示于图8)。可使用周遭环境(例如空气、氮气)填充间隙810。在一实施方式中,使用选择性湿式蚀刻制程移除第一磊晶层314。在某些实施方式中,选择性湿式蚀刻制程包含APM蚀刻(例如氢氧化氨-过氧化氢-水的混和物)。在某些实施方式中,选择性移除包含先氧化锗化硅,再移除锗化硅的氧化物(SiGeOx)。举例来说,可使用O3清洗来氧化,然后使用蚀刻液例如NH4OH移除锗化硅的氧化物(SiGeOx)。在一实施方式中,第一磊晶层314是锗化硅而且第二磊晶层316是硅,能够选择性移除第一磊晶层314。
如图9C及图9D所示,在移除N型场效晶体管区域212中的第一磊晶层314之后,使用蚀刻制程移除第一图案化硬遮罩730。在一实施例中,第一图案化硬遮罩730是光阻图案,使用湿式去除光阻(wet stripping)或/及等离子灰化(plasma ashing)移除第一图案化硬遮罩730。
参照图1及图10A-10B,方法100进行至步骤118,形成间隔层820于N型场效晶体管区域212和P型场效晶体管区域214的上方。间隔层820可为形成于N型场效晶体管区域212和P型场效晶体管区域214上方的保形(conformal)介电层。间隔层820可形成间隔元件于虚设栅极堆叠610的侧壁上。间隔层820也可填充上述步骤116移除磊晶层后提供的间隙810。为了清楚起见,在使用间隔层820填充间隙810后,磊晶堆叠310R称为310RS。
间隔层820可包含介电材料,例如氧化硅、氮化硅、碳化硅、氮氧化硅、氮碳化硅(SiCN)薄膜、碳氧化硅、SiOCN薄膜、或/及其组合。在某些实施方式中,间隔层820包含多层,例如主要间隔壁、衬里层、及其类似物。举例来说,可沉积介电材料于虚设栅极堆叠610上方形成间隔层820,使用的沉积制程例如化学气相沉积制程、次大气压化学气相沉积(subatmospheric CVD,SACVD)制程、可流动式化学气相沉积(flowable CVD)、原子层沉积(ALD)制程、物理气相沉积制程(physical vapor deposition,PVD)、或/及其他适当的制程沉积。在特定实施方式中,沉积之后可以回蚀(例如非等向性蚀刻)介电材料。
再次参照图1、图10A及图10B,方法100进行至步骤120,回蚀N型场效晶体管区域212和P型场效晶体管区域214中的间隔层820。在目前的实施方式中,回蚀间隔层820以曝露源极/漏极区域630中部分的鳍板410’。间隔层820可留在虚设栅极结构610的侧壁上形成间隔元件,而从虚设栅极堆叠610的顶面移除间隔层820。在某些实施方式中,回蚀间隔层820可包含湿式蚀刻制程、干式蚀刻制程、多重步骤蚀刻制程、或/及其组合。在N型场效晶体管区域212,当从曝露的磊晶堆叠310RS的顶面及水平面移除间隔层820,如图10A所示,间隔层820维持插入并配置于源极/漏极区域630中磊晶推叠310RS的第二磊晶层316的下方。间隔层配置于第二磊晶层316(例如纳米线)的下方。如图10B所示,在P型场效晶体管区域214中,从源极/漏极区域630中曝露的磊晶堆叠310移除间隔层820。
参照图1、图11A及图11B,方法100进行至步骤122,形成第一源极/漏极(S/D)区域特征830于N型场效晶体管区域212中,同时使用第二图案化硬遮罩840覆盖P型场效晶体管区域214。第二图案化硬遮罩840形成的方式在很多方面和上述图9B讨论的第一图案化硬遮罩730类似,包含前述讨论的材料。
在N型场效晶体管区域212中,可执行磊晶生长制程形成第一源极/漏极(S/D)区域特征830,磊晶生长制程提供磊晶材料包覆源极/漏极区域630中的磊晶堆叠310RS。在某些实施方式中,使用磊晶生长半导体材料835于第二磊晶层316上,形成第一源极/漏极(S/D)区域特征830。换句话说,磊晶生长的半导体材料835形成于纳米线316周围,这可被称为形成“包覆物(cladding)”环绕纳米线316。
在各种实施方式中,磊晶生长半导体材料835可包含Ge、Si、GaAs、AlGaAs、SiGe、GaAsP、SiP、或/及其他适当的材料。在某些实施方式中,磊晶生长半导体材料835可为在磊晶制程期间原处(in-situ)掺杂。在某些实施方式中,磊晶生长半导体材料835可不为原处(in-situ)掺杂,举例来说,而是执行布植制程掺杂磊晶生长半导体材料835。
因此,和虚设栅极堆叠610相关的第一源极/漏极特征830包含第二磊晶层316及磊晶生长材料835。间隔层820的介电材料插入第二磊晶层316中。各磊晶层316(例如纳米线)延伸至通道区域620内,从而形成多重通道、多重源极/漏极区域的装置。在一实施方式中,在N型场效晶体管区域212中,第一源极/漏极特征830从上方包覆五个纳米线316并延伸至通道区域620内。在形成第一源极/漏极特征830于N型场效晶体管区域212中之后,使用蚀刻制程移除第二图案化硬遮罩840。

可使用选择性蚀刻制程,例如选择性湿式蚀刻、选择性干式蚀刻、或其组合,移除虚设电极层614。移除虚设介电层520的方式在很多方面和上述图8讨论的蚀刻制程类似。移除第一磊晶层314的方式在很多方面和上述图9A讨论的蚀刻制程类似。图14A绘示间隙940取代通道区域620中的第一磊晶层314。可使用周围环境(例如空气、氮气)填充间隙940。通过移除第一磊晶层314,通道区域620中的磊晶堆叠310转变成到磊晶堆叠310R且曝露于第一栅极沟槽910内。然后使用蚀刻制程移除第四图案化硬遮罩930。在一实施例中,第四图案化硬遮罩930是光阻图案,使用湿式去除光阻(wet stripping)或/及等离子灰化(plasmaashing)移除第四图案化硬遮罩930。
参照图1、图15A及图15B,方法100进行至步骤130,形成第一最终栅极堆叠1010于第一栅极沟槽920内。第一最终栅极堆叠1010可为高介电常数介电质(high-K)/金属(metal)栅极堆叠,然而其他组成都有可能。在目前的实施方式中,第一最终栅极堆叠1010形成栅极,和栅极相关的通道区域620中的第二磊晶层316(纳米线)提供的多重通道,通道区域620被称为环绕式栅极(gate-all-around,GAA)装置。在目前的实施方式中,第一高介电常数介电质/金属栅极(HK/MG)结构1010形成于第一栅极沟槽920内。在各种实施方式中,第一高介电常数介电质/金属栅极结构1010包含介面层(interfacial layer)、形成于介面层上方的高介电常数栅极介电层1014、或/及形成于高介电常数栅极介电层1014上方的第一栅极金属层1016。此处使用和所述的高介电常数栅极介电质,包含具有高介电常数的介电材料,例如,大于热氧化硅的介电常数(约3.9)。
在某些实施方式中,高介电常数介电质/金属栅极堆叠1010的介面层可包含介电材料,例如氧化硅、硅氧化铪(HfSiO)或氮氧化硅(SiON)。可使用化学氧化、热氧化、原子层沉积、化学气相沉积、或/及其他适当的方法形成介面层。高介电常数介电质/金属栅极堆叠1010的栅极介电层1014可包含高介电常数介电层,例如氧化铪。可替代地,高介电常数介电质/金属栅极堆叠1010的栅极介电层1014可包含其他高介电常数介电质,例如TiO2、HfZrO、Ta2O3、HfSiO4、ZrO2、ZrSiO2、LaO、AlO、ZrO、TiO、Ta2O5、Y2O3、SrTiO3(STO)、BaTiO3(BTO)、BaZrO、HfZrO、HfLaO、HfSiO、LaSiO、AlSiO、HfTaO、HfTiO、(Ba,Sr)TiO3(BST)、Al2O3、Si3N4、SiON、氮氧化物、或其组合、或其他适当的材料。可使用原子层沉积、物理气相沉积、化学气相沉积、氧化、或/及其他适当的方法形成高介电常数栅极介电层1014。高介电常数栅极介电层1014也形成于P型场效晶体管区域214上方,之后高介电常数栅极介电层1014会被移除。
第一栅极金属层1016可包含单一层或替代性的多层结构、衬里层、浸润层(wetting layer)、黏着层(adhesion layer)、金属合金或金属硅化物;多层结构例如金属层的各种组合,金属层具有挑选过的功函数以增强装置的效能(功函数金属层)。举例来说,第一栅极金属层1016可包含Ti、Ag、Al、TiAlN、TaC、TaCN、TaSiN、Mn、Zr、TiN、TaN、Ru、Mo、Al、WN、Cu、W、Re、Ir、Co、Ni、其他适当的金属材料或其组合。在各种实施方式中,可使用原子层沉积、物理气相沉积、化学气相沉积、电子束蒸镀、或其他适当的制程形成第一栅极金属层1016。在某些实施方式中,栅极介电层1014及第一栅极金属层1016也形成于P型场效晶体管区域214上方,之后会被移除。
在各种实施方式中,可执行化学机械研磨制程移除在P型场效晶体管区域214的高介电常数栅极介电层1014及第一栅极金属层1016,并移除N型场效晶体管区域212中过多的高介电常数栅极介电层1014及第一栅极金属层1016,进而提供基本上平坦的装置200的顶面。
参照图1、图16A及图16B,方法100进行至步骤132,移除虚设电极层614及虚设介电层520以形成P型场效晶体管区域214中的通道区域620中的第二栅极沟槽1020。因此,磊晶堆叠310曝露于第二栅极沟槽1020内。蚀刻制程可包含湿式蚀刻、干式蚀刻、或/及其组合。在某些实施方式中,蚀刻制程用以选择性蚀刻虚设电极层614及虚设介电层520而基本上不蚀刻间隔层820、层间介电层910及第一最终栅极堆叠。因此,利用自我对准(self-alignment)的本质形成第二栅极沟槽1020,放宽制程上的限制。
参照图1、图17A和图17B,方法100进行至步骤134,在第二栅极沟槽1020内及磊晶堆叠310上方形成第二最终栅极堆叠1030以形成单一磊晶堆叠栅极。第二最终栅极堆叠1030可为高介电常数介电质/金属栅极的栅极堆叠,然而,其他组合也有可能。在某些实施方式中,第二最终栅极堆叠1030形成栅极associated with磊晶堆叠310,磊晶堆叠310具有多个第一磊晶层314作为多重栅极通道,多重栅极通道通过多个第二磊晶层316分隔以引入高效率的应变至栅极通道中,提升装置效能。
在各种实施方式中,第二高介电常数介电质/金属栅极堆叠1030包含介面层、形成于介面层上方的高介电常数栅极介电层1014、或/及形成于高介电常数栅极介电层1014上方的第二栅极金属层1036。形成第二高介电常数介电质/金属栅极堆叠1030的方式可在很多方面和上述图15A讨论的第一高介电常数介电质/金属栅极堆叠1010类似,包含前文讨论的材料。第二栅极金属层1036可包含单一层或替代性的多层结构、衬里层、浸润层(wettinglayer)、黏着层(adhesion layer)、金属合金或金属硅化物;多层结构例如金属层的各种组合,金属层具有挑选过的功函数以增强装置的效能(功函数金属层)。举例来说,第二栅极金属层1036可包含Ti、Ag、Al、TiAlN、TaC、TaCN、TaSiN、Mn、Zr、TiN、TaN、Ru、Mo、Al、WN、Cu、W、Re、Ir、Co、Ni、其他适当的金属材料或其组合。在各种实施方式中,可使用原子层沉积、物理气相沉积、化学气相沉积、电子束蒸镀、或其他适当的制程形成第二栅极金属层1036。
在各种实施方式中,可执行化学机械研磨制程移除在N型场效晶体管区域212的高介电常数栅极介电层1014及第二栅极金属层1036,并移除P型场效晶体管区域214中过多的高介电常数栅极介电层1014及第二栅极金属层1036,提供基本上平坦的装置200的顶面。
如方法100所示,N型场效晶体管区域的装置200N使用环绕式栅极结构且P型场效晶体管区域的装置200P是单一磊晶堆叠栅极。装置200N绘示于图17A中的等角视图且对应图18A(沿线段A-A穿过第一最终栅极堆叠1010的剖面)的剖面示意图、图18B(沿线段B-B穿过第一源极/漏极特征830的剖面)的剖面示意图、图18C(沿线段C-C穿过通道区域620及源极/漏极区域630的剖面)的剖面示意图。多重栅极装置200P绘示于图17B中的等角视图且对应图19A(沿线段A-A穿过第二最终栅极堆叠1030的剖面)的剖面示意图、图19B(沿线段B-B穿过第二源极/漏极特征850的剖面)的剖面示意图、图19C(沿线段C-C穿过通道区域620及源极/漏极区域630的剖面)的剖面示意图。
在N型场效晶体管区域212中,如图18A及图18C所示,栅极介电层1014配置于第二磊晶层316(例如纳米线)的下方。然而,在其他的实施方式中,第一高介电常数介电层/金属栅极堆叠1010的其他部分(例如第一栅极金属层1016)也可配置于第二磊晶层316下。在某些实施方式中,装置200可为鳍式场效晶体管装置,鳍式场效晶体管装置的栅极形成于通道区域620的至少两面上(例如顶面和两侧壁)。在目前的实施方式中,装置200在N型场效晶体管区域212中具有环绕式栅极。如前文所述,在目前的实施方式中,第二磊晶层316的厚度(纳米线的直径)被选为大于第一磊晶层314以增强N型场效晶体管的栅极电流。图18B及图18C的装置200绘示第一源极/漏极特征830,第一源极/漏极特征830具有磊晶生长包覆层835配置于第二磊晶层316(例如纳米线)的多个面上,而间隔层820配置于第二磊晶层316之间。间隔层820接触通道区域620中的栅极介电层1014。第一极/漏极特征830形成于磊晶堆叠310RS的上方,磊晶堆叠310RS具有多重纳米线且各纳米线(第二磊晶材料316)延伸至通道区域620中,进而形成环绕式栅极、多重源极/漏极的结构。在某些实施方式中,源极/漏极区域630的纳米线总数和通道区域中纳米线的总数相同。
在P型场效晶体管区域214中,如图19A及图19C绘示,栅极介电层1014包覆磊晶堆叠310周围,磊晶堆叠310具有被第二磊晶层316插入的第一磊晶层314。在某些实施方式中,装置200可为鳍式场效晶体管装置,鳍式场效晶体管装置的栅极形成于通道区域620的至少两面上(例如顶面和两侧壁)或/及具有其他的构造。在目前的实施方式中,装置200P在P型场效晶体管区域214中具有单一磊晶堆叠栅极。需要注意的是P型场效晶体管区域214的通道区域620中,第一磊晶层314的总数比N型场效晶体管区域212的通道区域620中的纳米线(第二磊晶层316)的总数多1,这是基于P型场效晶体管的效能考量,例如增强P型场效晶体管的栅极电流。
图19B及图19C中的装置200N绘示的第二源极/漏极特征850具有磊晶生长包覆层855配置于磊晶堆叠310上方。第二源极/漏极特征850延伸至通道区域620中,进而形成单一磊晶堆叠栅极、单一源极/漏极区域的结构。
额外的制程步骤可在方法100之前、期间及之后补充,而且根据方法100的各种实施方式,上述某些制程步骤可被取代或删除。
作为一实施例,形成装置200,使P型场效晶体管区域214的通道区域620中的第一磊晶层314总数相同于N型场效晶体管区域214的通道区域620中的纳米线(第二磊晶层316)总数。因为此缘故,在步骤104中,磊晶堆叠310的最上方的磊晶层式第二磊晶层316,而非第一磊晶层314。而且,在步骤124中,在形成在P型场效晶体管区域214的源极/漏极区域630中的第二源极/漏极特征850之前,使用选择性蚀刻制程移除最上方的第二磊晶层316。类似地,在步骤132中,在移除虚设电极层614及虚设介电层520以形成P型场效晶体管区域214中的通道区域620中的第二栅极沟槽1020之后,使用另一选择性蚀刻制程移除磊晶堆叠310最上方的第二磊晶层316。
