Description
技术领域
本发明通常涉及埋置SOI晶圆,尤其涉及在埋置SOI层中具有扩散阻挡物的埋置SOI晶圆。
背景技术
硅通孔(through silicon via;TSV)半导体装置包含铜并使用迁移离子例如钠或钾,包含例如化学机械抛光(chemical mechanical polish;CMP)制程。铜或迁移离子在封装或芯片使用期间可扩散穿过硅或氧化物并抵达装置例如FET或MOS电容器,从而导致阈值电压漂移以及其它装置退化。使用埋置氧化物(buried oxide;BOX)的绝缘体上硅晶圆被用来形成集成电路,而该BOX可为迁移离子或铜提供非预期的扩散路径。目前的趋势是使用具有较大弓形度及较高深宽比TSV(更短且更窄TSV)的较薄硅晶圆,从而进一步增加污染问题。
发明内容
在一个实施例中,一种SOI半导体装置包括:具有主动半导体层及第一氧化物层的第一晶圆;以及具有操作衬底及第二氧化物层的第二晶圆,该第一晶圆的该第一氧化物层与该第二晶圆的该第二氧化物层接合,其中,该第一晶圆及该第二晶圆的其中之一包括氮化物层。在一个实施例中,该第二晶圆包括形成于该操作衬底与该第二氧化物层之间的该氮化物层。在另一个实施例中,该第二晶圆包括形成于该操作衬底上的第三氧化物层,且该氮化物层形成于该第二晶圆的该第二氧化物层与该第三氧化物层之间。在又一个实施例中,该氮化物层形成于该第一晶圆的该主动半导体层与该第一氧化物层之间。在另一个实施例中,该第一晶圆包括形成于该主动半导体层上的第三氧化物层,且该氮化物层形成于该第一晶圆上的该第三氧化物层与该第一氧化物层之间。

具体实施方式
本发明涉及在厚度为十分之几纳米至数百纳米的范围内的二氧化硅层上依据要形成的半导体装置的类型,具有厚度为几十纳米至几百纳米的高质量硅层的SOI衬底的形成。另外,采用晶圆接合技术,其中,提供第一晶圆(常常被称为施体晶圆)并提供第二晶圆(常常被称为操作晶圆)。在该些晶圆的至少其中之一上生长或沉积具有所需厚度的二氧化硅层。该第一晶圆及该第二晶圆的至少其中之一包括氮化物层。随后,对该第一晶圆较佳地利用氢离子执行离子注入,其中,在该第一晶圆的良好定义的深度穿过该二氧化硅层注入离子,从而在该二氧化硅层与该氢的峰值浓度之间保持具有特定厚度的半导体层。可使用熟知的智能剥离(Smart-cut)制程。在该注入以后,将该第一晶圆与该第二晶圆接合在一起,其中,该第一晶圆的该二氧化硅与该第二晶圆的该二氧化硅形成接合界面;或者该第一晶圆的该二氧化硅与该第二晶圆的该硅形成接合界面。在该接合制程(其包括退火步骤)以后,该第一晶圆与该第二晶圆的复合物经历切割制程,其中,包括该注入氢离子的区域充当分隔层,以最终获得具有形成于二氧化硅层上的高质量硅层的SOI晶圆。接着,通过化学机械抛光(chemical mechanical polishing;CMP)和/或快速热退火处理该硅层,以获得所需的表面质量,如现有技术所已知。
请参照图1a至1e,现在将说明本发明的示例实施例,其原则上可采用如上所述的序列。在图1a及图1b中,提供第一衬底10,例如硅晶圆或任意其它合适的半导体衬底,以及第二衬底12,例如硅晶圆、玻璃晶圆或任意其它合适的操作晶圆。例如,第一及第二衬底10及12可为可从多个供应商处获得的用于标准集成电路制造的标准硅晶圆。衬底12经历标准背面处理,例如步骤:旋转冲洗-干燥(spin rinse-dry;SRD)、BW背接触、氢氧化钾(KOH)清洗、切割、背接触后清洗(其中氢氟酸将氧化物自操作晶圆剥离、含硫、标准清洗1、标准清洗2)以及接合清洗。半导体衬底10例如可包括硅、SiGe、SiC、GaN、InP、GaAs、AlGaN、InAlN、AlGaN,或其组合的至少其中一种。应当了解,依据应用,该操作或半导体晶圆可为N或P型,具有低或高的掺杂浓度。
第一衬底10具有形成于其上的具有所需厚度的绝缘层14。在一个特定实施例中,绝缘层14为二氧化硅层,具有约50纳米至0.05微米范围内的厚度。绝缘层14可通过现有技术中已知的任意合适的生长和/或沉积方法形成。例如,当作为二氧化硅层设置时,绝缘层14可通过氧化第一衬底10以形成热氧化物层而形成。
第一衬底10经历离子注入,以形成注入区16,其峰值浓度位于预定义深度,该预定义深度可通过注入参数及绝缘层14的厚度进行良好控制。较佳地,以适于在绝缘层16约10至500纳米下方设置注入区16的剂量及能量来注入氢离子。在二氧化硅层14与离子注入施体区16之间形成主动区18。
第二衬底12具有形成于其上的扩散阻挡层20,其组成及厚度经选择以在半导体装置制造期间可能发生的升高温度下充当铜原子及离子的扩散阻挡层。在图1b的实施例中,扩散阻挡层20为氮化物层22(其是有效防止铜原子及离子形式减轻其穿过的熟知介电材料)以及二氧化硅层24。依据制程要求,扩散阻挡层20的厚度可在10纳米至数百纳米的范围内。例如,如果第二衬底12是将作为操作晶圆被用于半导体装置的进一步制程及形成的硅晶圆,则扩散层20具有50纳米的厚度以在衬底12的制程期间降低或消除铜污染的可能性是有利的。若衬底12是其中铜具有明显较小的扩散系数的材料(与硅相比),则可选择扩散层20的厚度在10至200纳米范围内。扩散阻挡层20的形成可包括任意适当的沉积方法,例如等离子体增强型或低压化学及物理气相沉积,以形成例如氮化硅层22及二氧化硅层24。
图1c示意显示即将执行接合制程之前的第一衬底10及第二衬底12,其中,将扩散阻挡层20的氧化物层24与绝缘层14彼此相向布置。
在图1d中,形成复合结构26,包括衬底12、氮化物层22、氧化物层24、氧化物层14,以及衬底10的主动层18及施体层16。如前面所述,将衬底10与衬底12接合可能需要退火步骤,以确保复合衬底130的所需稳定性,其全部可通过使用已知的现有技术实现。
图1e示意显示在衬底10的注入区16的分离以后的衬底12。该两个衬底的该分离可通过在对应注入区16的位置的复合衬底26的周边的水射流来实现。接着,所形成的BOX结构28(其顶部上形成有主动层18)可经历任意表面处理,例如CMP,以针对该衬底的进一步制程获得所需的表面属性。
如上所述,本发明涉及形成具有嵌埋于SOI绝缘体中的氮化物或其它迁移离子和/或铜扩散阻挡物的SOI BOX晶圆的方法及结构。因此,与传统SOI衬底相反,依据本发明,BOX结构26包括扩散阻挡层30,其有效防止铜原子及迁移离子扩散穿过扩散阻挡层30进入主动层18。在此实施例中,扩散阻挡层30包括氮化物层22、氧化物层24以及氧化物层14。由于层14与24之间的氧化物:氧化物接合,BOX结构28的稳定性相对现有技术结构得到改进。
图1a至1e揭示本发明的BOX结构的一个实施例,其中,具有氮化物层及氧化物层的操作晶圆与具有氧化物层及智能剥离(smart cut)施体层的半导体晶圆接合。
图2a至2e揭示通过将具有氧化物层、氮化物层及氧化物层的操作晶圆与具有氧化物层及智能剥离(smart cut)施体层的半导体晶圆接合来形成BOX结构的制程。在此实施例中,衬底12包括形成于半导体衬底12上的氧化物层32,且氮化物层22形成于衬底12的氧化物层24与氧化物层32之间。在图2e中,所形成的SOI晶圆34BOX结构36包括扩散阻挡层22,其包括氧化物层14、24以及32。
图3a至3e揭示通过将具有氧化物层的操作晶圆与具有氧化物层、氮化物层以及智能剥离(smart cut)施体层的半导体晶圆接合来形成BOX结构的制程。在此实施例中,氮化物层22形成于半导体晶圆10的主动半导体层18与氧化物层14之间。在图3e中,所形成的SOI晶圆38包括BOX结构40,其包括氧化物层14、24以及氮化物层22。
图4a至4e揭示通过将具有氧化物层的操作晶圆与具有氧化物层、氮化物层、氧化物层以及智能剥离(smart cut)施体层的半导体晶圆接合来形成BOX结构的制程。在此实施例中,半导体晶圆10包括形成于主动半导体层18上的氧化物层32,且氮化物层22形成于氧化物层32与氧化物层14之间。在图4e中,所形成的SOI晶圆42具有BOX结构44,该BOX结构包括阻挡扩散层22,其包括氧化物层14、24以及32。
图5显示硅通孔(TSV)半导体装置50,其具有半导体装置层52,该半导体装置层52包括铜接触垫54以及TiW层56。装置50包括氮化物层58、氧化物层60以及层62。BOX层64包括具有主动半导体层及第一氧化物层的第一晶圆,以及具有半导体衬底及第二氧化物层的第二晶圆,该第二氧化物层与该第一氧化物层接合,其中,该第一晶圆及该第二晶圆的其中之一包括氮化物层;以及操作衬底层,如图1e至4e的其中一个中所示。层66包含半导体装置例如FET。层68为后端线路层,其事先被构建于该半导体衬底上。层69为最终金属终端,也被称为凸块下金属化层(under bump metallurgy)。层70为硅通孔,其将位于该半导体衬底的正面上的后端布线与该半导体衬底的背面连接。
TSV装置50形成自晶圆顶部(在BOX上方),穿过BOX,抵达薄化的操作晶圆背面。该TSV装置可为环形TSV、衬里/铜填充TSV或绝缘TSV。BOX中的SiN层可能需要在接合温度或更高温度下致密化,以避免在接合期间逸气或收缩。
尽管已就本发明的示例及所执行的实施例特别显示并说明了本发明,但本领域的技术人员将理解,可在其中在形式及细节上作上述及其它变更,而不背离本发明的精神及范围,本发明的精神及范围应当仅受所附权利要求的范围限制。
