Description
技术领域
本发明涉及一种用来剥离和清洁用的半水组合物,其特别适用于从半导体基片上剥离光致抗蚀剂并清洁包括蚀刻后残余物和积灰的有机和无机化合物。本发明还可用作二氧化硅蚀刻剂。这里所述的术语“半水”是指水和有机溶剂的混合物。本发明还包括使用这种组合物从半导体基片剥离光致抗蚀剂并清洁有机和无机化合物以及蚀刻二氧化硅的方法。更为特别的是,本发明描述了该方法中用来剥离、清洁并蚀刻的半水组合物及其工艺。该溶液中含有氟化物、亚砜或砜溶剂、水并可以含有其它的溶剂、阻蚀剂、螯合剂、碱性胺化合物、表面活性剂、酸和碱。
背景技术
含氟化物的化学物质与原硅晶片已在半导体工业中一同使用多年(该硅晶片是尚未用来离子嵌入或构造设备的硅片)。正常情况下,氟化物(通常为稀释的氢氟酸)用于所谓“RCA冲洗”的最后一步。该基片通常会被上级工序的单层量金属、阴离子和/或有机杂质或表面残余物(颗粒)所污染。这些杂质对简单测试设备结构的电学完整性产生强烈影响,并且这些结构必须在不损坏其完整性的条件下进行清洗。这类清洁方法包括在一些技术文献中讨论的技术,例如,1991年的mt.Conf.On Solid State Devices and Materials第484-486页或者Kujime,T.等人在Proc.of the 1996 Semi.Pure Water and Chemicals第245-256页上的文章以及Singer于1995年10月在P.Semi.International第88页上的文章。
那些教导出用低pH值溶液来清洁原晶片的方法的专利包括有美国专利US5,560,857以及US5,645,737、US5,181,985、US5,603,849、US5,705,089。
用氟化物化学物质(通常是HF)作为RCA清洁的最后一步可使硅晶片表面处于斥水的疏水态(其表面覆盖有Si-H基团)。在该步骤中,会有一定比例的晶片表面被溶解(除去)。除非对工艺条件(时间、温度、溶液组成)精确监控,否则基片会被损坏,这可参见Rafol,C等人于1997在J.Electroanalytic Chem.433第77-83页上发表的文章。许多组合物中都有水和有机溶剂。这些溶液中水的浓度非常关键。硅氧化物在HF/水中的蚀刻速率为21/分(@25℃),但在异丁醇中,该速率下降到2.14/分,在丙酮(疏质子溶剂)中该速率甚至更低为0.12/分,参见1998年8月5-7日在Stanford(斯坦福)大学进行的NSF/SRC Eng.Res.Center,Environmentally Benign Semiconductor Manufacturing。
在进行完前端(Front End of Line(FEOL))清洁处理之后,晶片通常要进行半导体设备的后端(Back End of Line(FEOL))加工处理,这里的设备可以是动态随机存贮器(DRAM)、静态随机读取存贮器(SRAM)、逻辑存贮器、可编程只读存贮器(EPROM)、互补金属硅存贮器(CMOS)等。现在,用化学反应(液态或等离子体)的蚀刻构造技术已用于此类半导体基片中来构造导线结构。
在晶片上沉积光致抗蚀剂膜以形成掩模,然后将基片设计成像在膜层上,经固化后用显影剂去除未显影的图像。然后用等离子能量激发的反应蚀刻气体通过蚀刻(电介质或金属)使保留图像转移到下层材料上。
蚀刻剂气体有选择地攻击基片上未形成保护的区域。多年来液体或湿蚀刻化学物质被大量并广泛地用来蚀刻金属、氧化物和电介质。这些化学物质具有很强的侵蚀性,能形成各向同性蚀刻(即在各个方向上的蚀刻相同)。
渐渐地人们开始使用等离子蚀刻、反应离子蚀刻或离子铣削技术,这类蚀刻工艺会因等离子气体、反应的物质以及光致抗蚀剂的相互反应而形成不希望的副产品。这类副产品的组成通常由蚀刻掉的基片、底层基片、光致抗蚀剂以及蚀刻气体构成。蚀刻设备的类型、工艺条件以及所用基片都会对副产品的形成产生影响。这些副产品通常是指“侧壁聚合物”、“遮避物”或“电子篱笆”,氧等离子或传统的溶剂很难将它们完全去除。通常用来剥离光致抗蚀剂的碱/溶剂混合物型剥离剂的实例包括:美国专利US4770713以及US4403029中所述的二甲基乙酰胺或二甲基甲酰胺和链烷醇胺;美国专利US4428871、US4401747、US4395479中所述的2-吡咯烷酮、二烷基砜和链烷醇胺;美国专利US4744834中所述的2吡咯烷酮和氢氧化四甲铵。然而,当金属结构主要涉及Al-Si或A1-Si-Cu并且“侧壁聚合物”残余物仅含有包含铝的有机金属化合物时,这类剥离组合物仅能从单层金属简单微电路结构中蚀刻的接触口和金属线上清除“侧壁聚合体”。
如果不能将蚀刻残余物从基片上去除,那么残余物将影响基片的后续工艺。因此当工业进展到亚微加工技术时,从基片上有效去除蚀刻残余物和光致抗蚀剂就变得非常重要了。这就需要一种去除溶液,该溶液能去除各类金属如铝、铝/硅/铜、钛、氮化钛、钛/钨、钨、二氧化硅、多晶硅等等离子蚀刻所形成的所有类型的残余物,同时不会侵蚀下层材料,该清洁溶液需要在处理区域具有更为有效的化学性质。不好地清洁效果会使设备的产量、可靠性和性能降低。
还有,如果这些残余物中的成分不能以一定的方式去除或中和,那么残余物将吸收湿气并形成酸性物质侵蚀金属结构。所形成的酸腐蚀导线材料从而产生不良结果如电阻增加和断线。这类问题经常出现,特别是在铝和铝合金用作导线材料时更是如此。如果不对晶片与酸性材料之间的接触进行控制,就会损坏金属结构。因此蚀刻完成后,有必要将蚀刻后抗蚀剂掩模从防护表面去除以便进行最后工序。
最好是开发出一种改进的清洁组合物来将有机聚合物从所涂的无机基片上清除下来,同时不侵蚀、溶解或钝化金属电路,或者改变晶片的化学结构。
现在是用酸性有机溶剂或碱性有机溶剂来去除侧壁残余物的。酸性溶剂通常由酚类化合物或者含氯溶剂和/或芳香族烃和/或烷基苯磺酸构成。这些配方通常都要在等于和大于100℃的温度条件下使用。正常情况下需要用异丙醇来漂洗这些化学物质。
此外,用来去除光致抗蚀剂涂层的剥离组合物以及用来去除蚀刻后残余物的清除组合物大多具有易燃性,对人以及环境都具有相当的危险性,其中所含的反应溶剂混合物具有相当的毒性。还有,这些组合物不仅有毒,而且处理起来成本很高,这是因为它们有可能要以有害废料的形式进行处理。此外,这些组合物通常具有严格的限制的浸渍寿命(bath life),并且多数情况不能再循环使用或再利用。
通常用于超大规模集成(ULSI)结构、步骤一致性更好的普通中间层电介质、TEOS(正硅酸四乙基酯)和硼磷硅酸盐玻璃(BPSG),它们接触通道周围的光致抗蚀剂通常是用HF溶液清除。HF一般不用来攻击电介质材料。这类攻击不希望的(参见Lee,C和Lee,5,Solid StateElectronics 4第921-923页(1997))。因此,需要一种更加环保的、用来剥离并清洁的配方。
稀释的氢氟酸溶液可在一定的条件下通过攻击电介质的通道侧壁来去除侧壁聚合物并因此改变设备的尺寸,并有可能改变介电常数,这可参见Ireland,P.的Thin Solid Films,304第1-12页(1997)。现有的含有HF、硝酸、水以及羟胺的化学物质在侵蚀性上足以蚀刻硅,这可参见A.Muller的US3592773。最近的信息表明HF的稀释溶液不能很好地清除新形成的CFx蚀刻残余物,这可参见K.Ueno等人在J.Electrochem.Soc.第144卷,(7)1997年的“Cleaning of CHF3Plasma-Etched SiO2/SiN/Cu Via Structures with Dilute Hydrofluoric AcidSolutions,”。开口于TiSi2上的接触通道很难用HF溶液进行清洁,因为其会攻击下层的TiSi2层。而且很难在狭窄的亲水性接触通道内大量运送化学物质,参见Baklanov,M.R.等人在Proc.Electrochem.Soc,1998年97-35第602-609页发表的文章。
最近基于氟化物的化学物质都是在限定的条件下用来去除蚀刻后的残余物。这些组合物中有许多都含有氟化物组分,特别是HF。此外,这些组合物可能会含有强腐蚀性化学物质(胆碱衍生物、氢氧化四烷基铵、氢氧化铵)如美国专利US5129955、US5563119或US5571447中公开的物质或者使用两相溶剂体系,该体系中其中一相为氢氟酸和水,另一相含非极性的有机溶剂(酮、醚、链烷烃、链烯烃)(参见美国专利US5603849)。其它的配方包括羟胺和氟化铵(参见Ward的美国专利US5709756)。其它的例子还有欧洲专利申请EP0662705中公开的季铵盐以及氟化物基组合物,美国专利US5630904中公开的有机羧酸铵或胺的羧化物和氟化物基组合物。
其它清洁晶片上的金属以及金属氧化物残余物的方法包括:将水蒸气喷到等离子灰化腔然后再引入含氟气体(氢氟酸)(参见美国专利US5181985),或者是一种含有氢氟酸、氟化铵以及水并且pH值在1.5到7之间的液体。
某些化学物质还可包括螯合剂以促进离子和阴离子杂质从晶片表面的去除(参见PCT/US98/02794),但螯合剂如柠檬酸、五倍子酸以及邻苯二酚等能够侵蚀铝金属线表面的氧化铝。Ohman和Sjoberg的研究表明柠檬酸离子的强复合性能够提高氧化铝的溶解性从而使露出金属被进一步腐蚀,在pH为5和6时,该系数为166和468(参见Ohman等人J.Chem.Soc.,Dalton Trans.(1983)的第2513页)。
其它抗蚀剂去除剂的化学物质如美国专利US5792274中公开的那些物质中包括有HF和水溶性有机溶剂和水结合的盐,其pH值在5到8之间。然而,其中没有提到使用氟化氢铵(二氟氢铵),该物质比氟化铵更为稳定,也没有提到共溶剂或者碱性胺化合物与DMSO和氟化物的协同组合物的应用。
2000年4月11日公开的,Misra等人的名称为“Benign Method forEtching Silicon Dioxide”的美国专利US6048406教导了采用二氟氢铵((NH4)HF2)的水溶液来替换氢氟酸,因为该物质对湿法蚀刻二氧化硅来说更好。然而,该专利文献没有教导使用一种能清除光致抗蚀剂或蚀刻残余物的配方。还有,其没有教导加入一种共溶剂或者碱性胺化合物的协同混合物。
1999年3月23日公开的,Rasmussen等人的名称为“Silicon DioxideEtch Process Which Protects Metal”的美国专利US5885477教导了采用氟化铵和氢氟酸与盐的水溶液来蚀刻二氧化硅,同时来减少侵蚀。然而,该专利文献没有教导使用二氟氢铵、共溶剂或者碱性胺化合物。
1985年4月2日公开的,Bartlett等人的名称为“PolymethylMethacrylate Compatible Silicon Dioxide Complexing Agent”的美国专利US4508591教导采用氟化铵和柠檬酸来蚀刻二氧化硅。然而,与Rasmussen等人一样,该专利文献没有教导使用二氟氢铵,共溶剂或者碱性胺化合物,同时也没有教导使用一种能清除光致抗蚀剂或蚀刻残余物的配方。
因此,需要开发出一种改进的二氧化硅蚀刻剂以及光致抗蚀剂和蚀刻后残余物的清除剂从而能从多种基片上将各种不需要的材料清除下来。特别是在集成电路的构造领域,人们越来越需要更好的去除性能同时避免攻击基片。这意味着适用于简单集成电路基片的组合物可能不能满足复杂集成电路构造的需要。这些组合物应当更为经济、环保,使用起来更为容易。
本发明教导了这样一种新的,改进了的用于剥离和清洁的组合物及其使用方法。本发明还包括二氧化硅蚀刻组合物及其使用。该组合物为水性的,能溶解有机和无机基片,并且在使用时能剥离并清洁多种基片。

此外,该组合物可选择地包含:碱性胺、共溶剂、阻蚀剂、螯合剂、表面活性剂、酸和碱。
作为优选,用来清洁并剥离的组合物由以下物质构成:氟化氢铵、DMSO、水以及共溶剂。该共溶剂选自乙酸、乙酸甲酯、乳酸甲酯、乙酸乙酯、二乙酸乙二醇酯、乳酸乙酯、丙二醇、碳酸亚丙基酯、N-甲基吡咯烷酮、甲氧基乙氧基乙醇以及聚乙二醇单月桂酸酯。

具体实施方式
电子设备的加工中通常要在加工过程中以特定的次数使用光致抗蚀剂的清除剂、蚀刻残余物的清除剂以及二氧化硅的蚀刻剂。为此已广泛使用的是含氟化物的配方。然而,某些含氟化物的化合物如氟化铵的配方由于其中的氨会从液相中蒸发出来,因此对二氧化硅的蚀刻速率不均匀。当氨从溶液中出来时,活性物质HF2 -和HF的浓度会增加,因此其对二氧化硅的攻击性会更大。此外,已发现使用氟化物如氟化铵和氢氟酸和溶剂如二甲基亚砜的水性配方不能在对下层材料不产生显著的侵蚀的同时提供足够的光致抗蚀剂和残余物的去除,除非再在配方中加入其它的化合物。
本发明公开了一种新的配方,其具有均匀的氧化硅蚀刻速率并能有效地去除光致抗蚀剂和蚀刻残余物,同时还能抑制下层材料的侵蚀。在一实施方案中,本发明应用了使用氟化氢铵的氟化物水溶液配方。氟化氢铵是一种更为稳定的氟化物,不会产生氟化铵以及氟化氢所出现的问题如氧化硅蚀刻速率不均匀和过度侵蚀等。
在另一实施例中,本发明使用含有亚砜和砜溶剂和共溶剂的氟化物水性配方,该共溶剂包括酯如乙酸甲酯、乙酸乙酯、乙酸丁酯、乳酸甲酯和乳酸乙酯;二醇如丙二醇;内酰胺如N-甲基吡咯烷酮等,其有助于氟化物配方清洁的有效性。
在另一实施方案中,本发明使用含有亚砜和砜溶剂和碱性胺化合物如2-氨基-2-乙氧基乙醇、单乙醇胺、单异丙醇胺等的氟化物水性配方,其有助于有效地清洁并有助于抑制侵蚀。
这些实施例可单独或组合使用。
本发明组合物的第一种组分是含氟化物的化合物,其可单独使用也可与其它至少一种含氟化物的化合物一起使用。该含氟化物的化合物或其混合物可根据情况进行选择,其重量百分比约在0.01%到10%之间。
合适的氟化物化合物为氟化铵、氟化氢铵以及氟化氢。优选的氟化物为氟化铵和氟化氢铵。最为优选的氟化物是氟化氢铵。为了去除残余物和光致抗蚀剂,氟化物的重量百分比最好从约0.01%到约10%。通常,组合物中氟化物的浓度越低,所需的使用温度就越高。
本发明的二氧化硅蚀刻组合物也包含一种或多种氟化物,但氟化物的重量百分比优选从约7%到约10%。
其中的R1和R2为H、OH或烷基,至少有一个是烷基。
合适的亚砜溶剂包括下面的一种或它们的混合物:二甲基亚砜(DMSO)、二丙基亚砜、二乙基亚砜、甲基乙基亚砜、二苯基亚砜、甲基苯基亚砜、1,1’-二羟基苯基亚砜等。
其中的R3-R10独立地为H或烷基。
合适的砜溶剂包括下面的一种或它们的混合物:二甲基砜、二乙基砜等。亚砜或砜溶剂或它们的混合物的重量百分比可根据情况的不同而不同,优选约在10wt%到95wt%之间。
优选实施方案中溶剂与水的比约为60∶40,尽管根据具体情况的不同也可更高或更低一些。在溶剂与水的比约为60∶40时,不会出现过度蚀刻并且所有的残余物都被去掉。过分提高该比值会导致通道侧壁出现过分的蚀刻。
如前所述,当含氟化物的化合物不是氟化氢铵时,其与亚砜溶剂的水溶液配方不会在形成足够的清洁作用的同时不出现明显侵蚀的情况。因此,如果不使用氟化氢铵,必须加入一种或多种共溶剂或碱性胺化合物来优化配方的效果同时减少侵蚀。合适的共溶剂包括下面的一种或它们的混合物:N-烷基内酰胺如N-甲基-2-吡咯烷酮;酯类化合物如乙酸、乙酸甲酯、乳酸甲酯、乙酸乙酯、乳酸乙酯;二醇如丙二醇、二乙酸乙二醇酯、聚乙二醇单月桂酸酯以及其它合适的共溶剂如碳酸亚丙基酯、甲氧基乙氧基乙醇等。
合适的碱性胺化合物包括下面的一种或它们的混合物:羟胺、肼、2-氨基-2-乙氧基乙醇(DGA)、单乙醇胺(MEA)、二乙基羟胺、胆碱、甲酸四甲基铵(TMAF)、单异丙醇胺(MIPA)、二乙醇胺(DEA)以及三乙醇胺(TEA)等。
现已发现氟化氢铵或二氟氢铵在稳定性上比其它氟化物高,并且由于其会产生HF2 -因此蚀刻速率更高。有意思的是,HF2 -对金属的侵蚀性很小。因此,现已发现,相对于其它的氟化物,氟化氢铵会使金属侵蚀最小。
除了上述组分之外,组合物还包含有水。通常情况下使用的是高纯度去离子水。
作为选择,组合物可包含本领域其它公知的溶剂,这包括酰胺类和多元醇类。
作为选择,组合物可包含有阻蚀剂。合适的阻蚀剂包括无机硝酸盐如硝酸铵、硝酸钾、硝酸钠和硝酸铷、硝酸铝以硝酸锌。
作为选择,组合物可包含有螯合剂。合适的螯合剂在1997年9月30日公开的美国专利文献US5672577中有描述,这里其以参考的形式并入本申请。加入螯合剂进一步提高了配方用来去除蚀刻残余物或光致抗蚀剂的有效性。
作为选择,组合物可包含有表面活性剂。合适的表面活性剂包括聚(乙烯醇)、聚(亚乙基亚胺)以及分类为阴离子、阳离子、非离子、两性离子和硅树脂基的任何表面活性剂组合物。优选的表面活性剂是聚(乙烯醇)和聚(亚乙基亚胺)。
某些组分的组合需要加入酸和/或碱从而将pH调节到合适数值。适用于本发明的酸为有机或无机酸。该酸可包括硝酸、硫酸、磷酸、盐酸(尽管盐酸对金属有腐蚀性)以及有机酸、甲酸、乙酸、丙酸、正酪酸、异丁酸、苯甲酸、抗坏血酸、葡萄糖酸、果酸、丙二酸、草酸、丁二酸、酒石酸、柠檬酸以及五倍子酸。
适用来调节清洁溶液pH值的苛性组分可由任何普通的碱组成,即氢氧化钠、氢氧化钾、氢氧化镁等。该组分的主要问题是会将游离的离子引入最后的配方中。游离的离子会损坏当今半导体工业中制造出的计算机芯片。其它可用的碱包括氢氧化铵或其衍生物,这包括三甲基-2-羟乙基氢氧化铵(胆碱)等。
采用本发明清洁组合物来清洁基片的方法涉及以下步骤:使其上有残余物特别的有机金属残余物或金属氧化物残余物的基片在一定温度下与本发明的清洁组合物接触一段时间以便去除残余物。作为选择,其中可使用搅拌、摇动、循环、超声波或本领域公知的其它技术。基片通常浸入到清洁组合物中。根据基片要被除去的特定材料来确定上述时间和温度。通常来说,温度可在环境温度或室温到100℃之间,优选为55℃,接触时间约为1到60分钟,优选为5-30分钟。通常在使用该组合物后要对基片进行漂洗。优选的漂洗溶液为异丙醇和DI水。
本发明的组合物特别适用于从金属和通道(via feature)上去除残余物,但也适用于剥离光致抗蚀剂。本领域普通技术人员都容易确定本发明组合物作为光致抗蚀剂剥离剂的应用。同样,本发明的组合物也可用来蚀刻金属或氧化物。本领域的普通技术人员很容易就能确定该组合物的用途和条件。
采用氟化氢铵除了上述的好处之外,现已发现将碱性胺化合物如2-氨基-2-乙氧基乙醇等加入到含氟化物和有机亚砜和/或砜溶剂的水性配方中能够有效地中和HF,形成例如氟化季铵盐,其反应如下:
由于F-离子不会攻击二氧化硅,因此该配方的侵蚀性很低并且能减少不必要的蚀刻。
已发现将共溶剂如乳酸乙酯等加入到含有氟化物和有机亚砜和/或砜溶剂的水溶液配方中能够提高配方去除蚀刻残余物和光致抗蚀剂的能力。乳酸乙酯去除蚀刻残余物的作用是由于疏水性/亲水性平衡、浸湿能力的改变以及/或混合物极性的改变。加入共溶剂如乳酸乙酯等能够通过氟化物物质、溶剂化作用和溶解作用产生活性化学攻击。
例1.一组含有氟化铵、水和亚砜或砜溶剂的清洁化学物质,其用TiN/A1Cu/TiN/Ti/氧化物的叠层金属晶片进行测试,该晶片用市场可买到的蚀刻剂氯化的等离子体进行蚀刻。蚀刻后带有残余物的金属晶片被切成小的样本片,然后将样本片浸入表1的化学溶液中在室温下进行清洁处理5分钟。取出样本片,用去离子水漂洗,用N2气吹干。用Hitachi4500 FE-SEM进行扫描电子显微观察以便评估其清洁和侵蚀效果。可通过肉眼对比的方法对金属叠片上残余物的去除和侵蚀效果进行测评,结果分为1到10个等级。表1中的配方采用重量百分比。

结果表明含DMSO的配方具有最佳的清洁性能与最小程度的侵蚀性的结合,仅对铝有轻微的攻击。据此,选择DMSO来进一步研究从而获得更好的配方。
例3.制备重量百分比为42.6%的乳酸乙酯、28.4%的DMSO、28.4%的水以及0.4%的氟化氢铵的混合物来从基片上清洁蚀刻残余物。图1所示为蚀刻残余物的去除效果。
例4.用氟化氢铵或双氟氢铵来代替氟化铵和氢氟酸。结果见图4A-4C,结果最好的是氟化氢铵,其有效地去除了蚀刻残余物,同时没有过分蚀刻被清除的通道。
例5.对不同功能组的清洁性能进行研究。用丙二醇作为羟基来源、乙酰基丙酮作为羰基来源,DGA作为氮来源。如图5A-5C的SEM所示,羟基有助于底层残余物的去除,同时羰基有助于通道侧壁上残余物的清洁。将这些组分混合发现:对清洁有两个有益的效应(乙醇和酮)出现在混合物中。这个新的发现引起了我们对酯基去除残余物和光致抗蚀剂的能力的研究,该酯基根据在羧酸/二醇和酮之间极性构成中间官能团。所测的第一酯化合物为乙酸甲酯,其结果良好。如图6A和6B所示,二乙酸乙二醇酯和乳酸乙酯的测试进一步证实了酯基的有益作用。由于其在水溶液中具有更高的溶解性,因此乳酸乙酯为优选酯和优选的共溶剂。
不同的溶液可具有不同的DMSO/ESTER/DIW比。已发现在乳酸乙酯的情况下该优选比率为1/1.5/1,其结果见图7的SEM结果。
基于例1的结果,可对具有不同浓度DMSO的配方进行测试从而确定在有水的条件下与氟化铵结合的有效范围。所示结果表明对清洁蚀刻抗蚀剂而言,DMSO在重量百分比约10%到约95%之间均有效果,加入碱性有机胺或共溶剂可提高配方的性能。下表展示的配方比单独使用DMSO的配方更为有效。
