半导体工艺设备如等离子体腔的一种包括一个含富勒烯的表面的抗腐蚀部件,及其制造方法。
Description
发明背景
发明领域
本发明涉及半导体工艺设备以及提高这些部件抗腐蚀性的方法。
相关技术描述
在半导体工艺领域中,通常使用真空工艺腔来在衬底上进行材料的刻蚀和化学气相沉积(CVD),将刻蚀或者沉积气体供入真空腔中,并对气体施加一种RF场将气体激发到等离子体状态。在专利号为4340462,4948458,5200232和5820723的共同所有的US专利中公开了平行板式变压耦合等离子体(TCPTM),也叫做电感耦合等离子体(ICP),和电子回旋共振(ECR)反应器及其部件的例子。由于这些反应器中等离子体环境的腐蚀性以及极小化颗粒和/或重金属污染的需要,高度希望这些设备的部件呈现出高的抗腐蚀性。
在半导体衬底的处理过程中,衬底一般用衬底夹具例如机械钳和静电钳(ESC)固定在真空腔中。这些钳制系统及其部件的例子可以在专利号为5262029和5838529的共同所有的US专利中找到。处理气体可以通过许多方式供入腔室中,比如通过气体喷嘴,导气环,气体分布板等。在专利号为5863376的共同所有的US专利中可以找到一种用于电感耦合等离子体反应器的温控气体分布板及其部件的例子。除了等离子体腔室设备,在半导体衬底处理过程中使用的其它设备包括传送机构,气体供应系统,衬里,起落机构,加载锁,室门机构,机械臂,紧固件及其它类似的设备。这些设备的部件要承受多种与半导体工艺相关的腐蚀条件。而且,考虑到半导体衬底处理对高纯度的需要,如硅晶片及介电材料如用于平板显示的玻璃衬底,高度希望在这些环境中的部件具有改善了的抗腐蚀性。
通常地,将铝和铝合金用于等离子体反应器的器壁,电极,衬底支撑,紧固件及其它的部件。为了防止这些金属部件的腐蚀,已提出了在铝表面用各种涂层进行涂覆的多种技术。例如,在专利号为5641375的US专利中公开了进行了阳极化处理的铝腔室壁,减少了等离子体对腔壁的侵蚀和磨损。专利’375指出,阳极化层最终会被溅射掉或刻蚀掉,腔室必须进行更换。专利号为5895586的US专利指出,可以在序列号为62-103379的日本申请公开中找到一种技术,来在铝材料上制备Al2O3,AlC,TiN,TiC,AIN或者其它类似的抗侵蚀膜。
专利号为5680013的US专利指出,在专利号为4491496的US专利中公开了一种在刻蚀腔室的金属表面火焰喷镀Al2O3的技术。专利’013指出铝和陶瓷涂层如氧化铝间的热膨胀系数的不同会导致涂层因热循环而开裂,涂层最终在腐蚀环境下失效。为保护腔壁,专利号为5366585,5798016和5885356的US专利提出了衬里配置。例如,专利’016公开了一种因其易加工性而优选的与铝共用的由陶瓷,铝,钢和/或石英组成的衬里,并涂覆一个氧化铝,Sc2O3或者Y2O3涂层来为铝针对等离子体提供保护,优选的是Al2O3。专利’585公开了一种独立式陶瓷衬里,厚度至少为0.005英寸,由固体氧化铝加工而成。专利’585提到通过火焰喷镀或者等离子体喷镀氧化铝,也能提供不用消耗下面的铝即可沉积的陶瓷层。专利’356公开了用于晶片基座的一种氧化铝陶瓷衬里和一种氮化铝陶瓷屏蔽。专利号为5885356的US专利公开了在CVD腔室内可用的陶瓷衬里材料。
对于半导体工艺设备的金属部件已提出了多种涂层。例如,专利号为5879523的US专利公开了一种溅射腔,其中在诸如不锈钢或者铝的金属上应用了一种热喷镀Al2O3涂层,并且二者之间有一个可选的含NiAlx键合的涂层。专利号为5522932和589153的US专利公开了一种用在衬底等离子体处理设备的金属部件上的铑涂层,二者之间有一个可选的镍涂层。专利号为5680013的US专利公开了一种在等离子体工艺腔室中保护金属表面的非键合陶瓷,优选的陶瓷材料是烧结AlN,其次优选的材料包括氧化铝,氟化镁和氧化镁。专利号为5904778的US专利公开了一种在独立式SiC上的SiC CVD涂层,可用作腔室壁,腔室顶或者围绕晶片的套环。
对于等离子体反应器的部件,如莲蓬式喷头气体分布系统,已有针对莲蓬式喷头材料的许多提议。例如,专利号为5569356的共同所有的US专利公开了一种由硅,石墨或者碳化硅制成的莲蓬式喷头。专利号为5494713的US专利指出,可在铝电极上制备一种防蚀钝化铝膜,并在该钝化膜上加覆一个硅涂层膜,如氧化硅或者氮化硅。专利’713指出,由于铝涂层膜,防蚀钝化铝涂层膜和硅涂层膜具有不同的线膨胀系数,硅涂层膜的厚度应为10μm或者以下,优选的为5μm,硅涂层膜太厚时容易产生裂纹。然而,厚度低于5μm,由于对铝衬底的保护不充分,因而是不可取的。专利号为4534516的US专利公开了一种不锈钢,铝,铜及其它类似材料制成的上部莲蓬式喷头电极。专利号为4612077的US专利公开了一种镁制成的莲蓬式喷头电极。专利号为5888907的US专利公开了一种无定形碳,SiC或者Al制成的莲蓬式喷头电极。专利号为5006220和5022979的US专利公开了一种莲蓬式喷头电极,要么完全由SiC制成,要么是将通过CVD沉积的SiC涂覆在碳基体上,提供一个高纯SiC的表面层。
考虑到半导体工艺设备部件对高纯度和抗腐蚀性的需求,在该领域内,对用于这些部件的材料和/或涂层需要进行改善。而且,对于腔室材料来讲,能够提高等离子体反应器腔室的使用寿命,从而减少设备的停机时间的任何材料将有利于降低半导体晶片处理的成本。
上述说明总结了用于衬底上材料的刻蚀和CVD真空工艺腔室的一般操作,这是通过相真空腔室供应刻蚀或沉积气体并对气体施加RF场以将气体激发到等离子态。基于这个背景,对于理解本发明重要的第二个无关的技术领域是与富勒烯相关的研究领域。富勒烯,有时称为巴基球或巴克敏斯特富勒烯,是一类纯碳分子,其中碳原子形成一个封闭的球。最常讨论的富勒烯是C60和C70。C60富勒烯分子由60个碳原子连接在一起组成,形成一个笼状结构,由20个六边形和12个五边形的面对称摆列成足球状结构。C60分子形成一个具有面心立方结构的紧密堆积的固体分子材料。C70的结构具有25个六边形,产生类似于橄榄球的结构。
自从1985年发现了富勒烯,研究人员已经研究了它们的性质并开发了其分子的应用。对于这点,由许多专利详细说明了含富勒烯的膜和涂层的应用。参见,例如美国专利5271890,5310699,5356872,5368890,6374463,5380595,5380703,5395496,5876790和5558903。
发明简述
本发明的第一个方面,提供一种方法,该方法可以在半导体工艺设备部件表面提供一种抗侵蚀的含富勒烯的涂层。该方法包括在半导体工艺设备部件表面沉积一种含富勒烯的涂层,以形成一个抗侵蚀的外表面。抗侵蚀表面,意味着表面涂层抵抗等离子体腔室气体对涂层的刻蚀时,保护下面的材料免于等离子体腔室气体的腐蚀作用。下面的被涂覆的工艺设备部件的表面可包含一种金属,陶瓷或者聚合物材料。实际上,在半导体工艺设备的表面和含富勒烯的涂层之间,可以使用一种或者多种中间金属,陶瓷或者聚合物涂层。用于等离子体腔室的可被涂覆的金属的表面包括阳极化铝或非阳极化铝,不锈钢,难熔金属如钼或其它金属或者合金。可被涂覆的陶瓷的表面包括氧化铝,SiC,AlN,Si3N4,BC或者其它与等离子体相容的陶瓷材料。可被涂覆的聚合物的表面包括含氟聚合物如Teflon,聚酰亚胺如Vespel和其它可在达200℃的温度下用于等离子体腔室的聚合物材料。

本发明的另一个方面,提供一种由含富勒烯的材料制成的半导体工艺设备部件。该部件可以包括用于该设备的任意的一种或者多种涂层。
附图简述
结合附图对其优选的实施方案进行下面的详述将使本发明的目的和优势变得明显,附图中:
图1是等离子体反应器腔室的剖面示意图,其中含有一个根据本发明涂覆了一种抗腐蚀涂层的部件。
图2是图1中细节A中的抗腐蚀涂层的详细说明图。
本发明的优选实施方案详述
本发明通过利用一种抗侵蚀涂层,为给半导体工艺设备部件如等离子体工艺反应器腔室部件的金属,陶瓷和聚合物表面提供抗腐蚀性提供了一种有效的方法。这些部件包括腔室壁,衬底支撑,气体分布系统包括莲蓬式喷头,折流板,套环,喷嘴等,紧固件,加热元件,等离子体屏,衬里,传输模块部件,例如:机械臂,紧固件,内外腔室壁等,以及其它部件。
尽管本发明适用于任意类型的具有金属,陶瓷或者聚合物表面的部件,为了便于说明,结合参考在专利号为5820723的US专利中描述的设备来对本发明作更详细的描述,这里对整个专利作了参考。
图1示意的是一个真空工艺反应器腔室10,包括衬底支撑70,其为衬底60提供一个静电钳力,当用He背冷时也为衬底提供一个RF偏置。聚焦环72,在衬底上方限定了一个等离子体域。能量源,以在腔室中保持高密度(如1011-1012离子/cm3)的等离子体,例如由适宜的RF源驱动以提供高密度等离子体的天线40,放置在反应器腔室10的顶部。该腔室包括适宜的真空泵浦设备,通过在腔室底部的位于中心的真空接 20将腔室抽空,以使腔室的内部30保持在所希望的压力(例如低于50mTorr,一般的在1-20mTorr)。
在天线40和工艺腔室10的内部之间是一个基本上具有均一厚度的平面介电窗50,其在工艺腔室10的顶部构成真空壁。在窗50下面是一个气体分布板52,其上包含诸如圆孔的开口,以使处理气体从供气处传递到腔室10中。一个锥形的衬里54从气体分布板延伸出来并包围在衬底支撑70之上。
在操作中,将半导体衬底如硅晶片60放置在衬底支撑70上,典型地,当使用He背冷时,用一个静电钳74来固定。然后通过使处理气体穿过窗50和气体分布板52之间的间隙将处理气体供给到真空工艺腔室10中。在申请号为08/509080,08/658258和08/658259的共同所有的US专利中公开了适用的气体分布板配置(如莲蓬式喷头),据此将这些公开资料作为参考。例如,尽管在图1中的窗口和气体分布板配置是平面的并有均一的厚度,对窗口和/或气体分布板而言,可以用非平面的和/或非均一厚度的几何形状。通过向天线40施加适宜的RF源,在衬底和窗口之间的空间里触发高密度的等离子体。
腔室壁28,比如阳极化或非阳极化的铝壁,和金属,陶瓷或者聚合物部件,比如衬底支撑70,紧固件56,衬里54等,暴露在等离子体中并表现出腐蚀征兆,根据本发明,选择将这些部件进行涂层,这样,在等离子体腔室的操作中就不需要把它们罩住。可被涂覆的金属和/或合金的例子包括阳极化或非阳极化铝及其合金,不锈钢,难熔金属如W和Mo及其合金,铜及其合金等。可被涂覆的陶瓷的表面的例子包括氧化铝,SiC,AlN,Si3N4,和BC。商业可获的可被涂覆的聚合物材料的例子包括含氟聚合物如Teflon,聚酰亚胺如Vespel和其它在达200℃的温度下可用于等离子腔室的聚合物材料。在一个优选的实施方案中,被涂覆的部件是具有一个阳极化或者非阳极化铝的表面29的腔室壁28。根据本发明,涂层允许使用铝合金而不用考虑它的组成(这样除了高纯铝外,还允许使用更经济的铝合金),晶粒结构或者表面条件。在下面的讨论中,被涂覆的部件的例子是一个铝腔室壁28,其具有一个可选的第一中间涂层80,一个可选的第二中间涂层90和一个含富勒烯的涂层100,如图2中所示。
为了保证涂覆材料的好的粘附性,优选地,在涂覆之前,将铝衬底28表面彻底净化以除去表面物质,比如氧化物或者油脂。另外,特别希望的是,在应用任意所希望的涂层之前,将衬底表面粗化,阳极化衬底表面并对阳极化的衬底表面再次粗化。
根据本发明,可选地,通过一种传统技术将第一中间涂层80涂覆在铝侧壁28上。这种可选的第一中间涂层80是足够厚的,以粘附在衬底之上并进一步允许在制备可选的第二中间涂层90或者下面要提及的含富勒烯的涂层100之前对其进行处理。第一中间涂层80可以是任意适用的厚度,比如至少大约0.001英寸的厚度,优选的从大约0.001到大约0.25英寸,更优选的在0.001和0.1英寸之间,最优选的在从0.001英寸到0.05英寸。
在将可选的第一中间涂层80沉积到铝衬底28上之后,镀层可以用任意适用的技术来进行喷砂或者粗化,然后,用可选的第二涂层90或者含富勒烯的涂层100来涂覆。粗化层80提供相当好的键合。所希望地,第二中间涂层90给涂层80带来高的机械压缩强度并在涂层90中减少裂缝的形成。
可选的第二中间涂层90是足够厚的,以粘附在第一中间涂层80上,并进一步允许在制备任意附加的中间涂层或者下述的含富勒烯的外部涂层100之前对其进行处理。第二中间涂层90可以是任意适用的厚度,比如至少大约0.001英寸的厚度,优选的从大约0.001到大约0.25英寸,更优选的在0.001和0.1英寸之间,最优选的在0.001英寸和0.05英寸之间。

所希望地,可选的第一和第二中间涂层80和90可以是上述材料的任意一种,这样依赖所预想的性能,涂层可以是相同的或者不同的。也希望可以采用相同或者不同材料的附加中间层如第三,第四或者第五中间层。
含富勒烯的涂层100沉积在可选的第二中间层90上,或者可选的第一中间层80上,或者直接在铝衬底28上。含富勒烯的涂层的所希望的厚度是至少0.001英寸;优选的从大约0.001到大约0.25英寸,更优选的从大约0.001到大约0.2英寸,更优选的从大约0.001到大约0.1英寸,最优选的在从0.001到0.05英寸。含富勒烯的涂层100的厚度可以选择以与在反应器中遇到的等离子体环境(如刻蚀,CVD等)相容。这种含富勒烯的涂覆层可以将上述反应器腔室和部件整个涂覆,或者部分涂覆。
含富勒烯涂层,这里指包含或者由掺杂或未掺杂的碳富勒烯形成的涂层,富勒烯有时称为巴基球或巴克敏斯特富勒烯。最常讨论的富勒烯是C60和C70。C60富勒烯分子包含连接在一起的60个碳原子,形成一个笼状结构,由20个六边形和12个五边形的面对称摆列成足球状结构。C60分子形成一个具有面心立方结构的紧密堆积的固体分子材料。C70的结构具有25个六边形,产生类似于橄榄球的结构。
优选的涂层包括纯的C60和C70,它们的混合物,任何一种或几种更高级的富勒烯,如C76,C78,C84,C92等,或C60,C70与任何一种或几种更高级富勒烯的混合物。可能有任何一种或几种富勒烯被排除在含富勒烯涂层中。
还希望,本发明中有所谓的掺杂富勒烯。这些分子包括含一种或几种掺杂物质的富勒烯,掺杂物质如碱金属或卤素原子。掺杂浓度希望小于或等于富勒烯涂层重量的1%,更希望的在富勒烯涂层重量的约100ppm和1%之间,且尤其希望的在富勒烯涂层重量的约0.001%和0.1%之间。
或者,本发明的含富勒烯的涂层可以是任何一种上述富勒烯与其它材料或化合物的复合物,该复合物形成一种硬质耐腐蚀表面。该复合物希望具有含富勒烯材料的连续的基体相。该复合材料中可以包含其它的保护性材料,其量可达整个复合材料的50%或者更多。更希望地,本发明的复合材料按重量比包括占复合材料约1%到40%的附加材料,更希望的是按重量比包括约1%到20%的附加材料,进一步更加希望的是按重量比包括约1%到10%的附加材料。在某些情况下,特别是当成本非常高时,富勒烯的百分比可以非常低,如低于涂层重量的20%,10%,5%和1%。
这些材料可以包括在等离子体工艺腔室中采用的任意一种或者多种材料。这些材料的例子包括任意一种或多种难熔金属,含这些金属的复合材料或合金。尤其希望的陶瓷包括Al2O3,SiC,Si3N4,BC,AIN,TiO2等。尤其希望的聚合物包括含氟聚合物如Teflon,聚酰亚胺如Vespel和其它的在达200℃的温度下可用于等离子体腔室的聚合物材料。相信最希望的材料将包括单独存在的或者与例如铪,钽,钛和/或硅的碳化物,硼化物,氮化物和/或碳氮化物;碳化硼;氮化硼;碳氮化硼;氧化锆;氧化钇,或者任何上述材料的混合物相结合的富勒烯。
本发明中的含富勒烯的涂层100可用任何合适的技术来沉积到所希望的表面上,如化学气相沉积,热喷涂,等离子体喷涂,升华,激光蒸发,溅射,溅射沉积,粒子束涂层,喷敷涂层,浸镀,蒸发,辊涂,毛刷涂层等。还希望将一层或多层含富勒烯的涂层与或者不与其它材料的中间层一起用这些已知技术沉积到所希望的表面上。
在本发明的一个可选的方面,提供一种由含富勒烯的材料制成的半导体工艺设备部件。该部件可以包括传统地用于该设备的任意一种或者多种涂层。
通过使用本发明的含富勒烯的涂层或者部件,优选的可获得一种超硬的,抗侵蚀的表面。在该涂层或者部件中,希望不含那些与工艺腔室气体发生不利反应的物质而且/或者是化学惰性的,这样就有低的颗粒污染或者没有颗粒污染,对下面的衬底轻微的腐蚀或者没有腐蚀,轻微的金属污染或者没有金属污染及/或少量的挥发性的刻蚀产物或者没有挥发性的刻蚀产物,这些产物不利地影响所处理的产品或反应器部件。由于富勒烯是碳基的,它们的等离子体处理中挥发且能够从腔室中排出而不会污染处理的产品,如硅晶片。
优选地,含富勒烯的涂层或者部件放在那些会或者不会暴露在等离子体环境下的区域里,如直接与等离子体接触的部分或者腔室部件后面的部分,如衬里等,以将在反应器腔室中处理的半导体衬底的金属污染最小化。尤其优选的是要限制或者排除过渡金属的尘埃;比如在周期表中的元素21到29(钪到铜),39到47(钇到银),57到79(镧到金)和所有从89(锕)往后的所知元素中的任意的一种或者多种元素。所以,本发明的一个优势就是通过抑制这些因刻蚀或者腐蚀而产生的尘埃,在沉积膜上减少了所不满意的刻蚀或者不希望的针状气孔的形成。
尽管已结合其具体的实施方案,对本发明进行了详细的描述,对本领域技术人员来讲,明显地,不脱离所附权利要求的范围,可进行多样的变化和改善,并可等价地采用。
