Abstract
提供了在3位受到保护的N-乙烯基内酰胺衍生物,它由通式(I)表示。这些衍生物被聚合成均聚物和共聚物,并用于半导体制造的微平版印刷方法。该聚合物用作适合于深UV处理的光刻胶原料,从而能够获得具有高灵敏度和高分辨率的图象。还有,通过使用本发明的光刻胶,能够形成超细电路并能够在图案形成上具有优异的改进。
Description
本发明涉及新型的N-乙烯基内酰胺衍生物和其用于微平版印刷的聚合物。更具体的说,本发明涉及N-乙烯基内酰胺衍生物和其用作光刻胶的原料的聚合物,该光刻胶通过使用深紫外光(UV)能够形成高灵敏度和高分辨率的图象,以及涉及它们的用作光刻胶的均聚物和共聚物。
通常,光刻胶主要由碱可溶的苯酚(或甲酚)-甲醛清漆树脂和作为光敏材料(光活性成分)的取代萘醌二叠氮化物化合物组成,这在US No.3,666,473,4,115,128和4,173,470中有描述。
在用于此类光刻胶的酚醛清漆树脂溶于碱的水溶液的同时,萘醌光敏材料用作光刻胶的溶解抑制剂。然而,当涂有光刻胶的基底选择性地进行化学辐射时,光敏剂被诱发这样一种结构变化:光刻胶涂层的暴露区域比未暴露区域具有更强的碱溶解性。借助于这一溶解度差异,能够在基底涂层上刻蚀出可靠的图象。即,当基底被浸入碱性显影液中时,光刻胶涂层的暴露区域被溶解,而未暴露区域基本上不受影响,得以形成图象。然而,上述酚醛清漆树脂型光刻胶已发现不适用于将来使用的采用较短波长的分挡器(steper),因为它们在深紫外光范围内(200-300nm)显示出较高的吸光性。
为了在半导体制造的平版印刷工艺中获得高的灵敏度,最近已开发了化学放大光刻胶。事实上,化学放大光刻胶已经引起人们的注意,因为已发现它能够比普通的正性酚醛清漆树脂光刻胶提高100倍的灵敏度。化学放大光刻胶,它利用光化酸产生剂(photoacid generator)(下文称作“PAG”),一般是通过在具有易与酸反应的结构的母体聚合物中配制PAG而获得的。对于光化反应的机理,当PAG暴露于光或受高能束如X射线和电子束的辐射时,会产生强质子酸,布朗斯特酸,引起母体聚合物的主链或侧链发生分解反应,交联反应或极性改变很大。酸的这一作用在辐射区域中引发所给定的显影溶液的溶解性的变化。即,或者提高,或者下降。结果能够形成精细的图象。
能够对光和辐射作出反映的嗡盐已知可用作光化酸产生剂。嗡盐典型地包括铵盐,氧嗡盐和锍盐等。近年来已有报道,有机磺酸酯能够用作所产生的光化酸。
适合作为能够与酸反应的母体聚合物的是,例如,具有侧链如叔丁基酯、叔丁基碳酸酯、叔丁氧基或叔丁氧基羰基的聚合物,这些侧链能够被酸分解成羧酸,酚或醇官能基。在这类侧链保护基团当中,叔丁氧基羰基在敏感性上是最高的。处在被保护状态或在与酸反应前的此类可与酸反应的聚合物能够溶于有机溶剂,但不溶于碱的水溶液。但是,如果可与酸反应的聚合物通过与酸反应被去保护,它会溶于碱的水溶液,因为它的极性显著变化。
通过使用这一原理,化学放大光刻胶的开发已是近年来热门的话题。叔丁氧基羰基保护的聚乙烯基苯酚(下文称作“t-bocPVP”),据报道,是最有希望的树脂中的一种,这在US No.4,491,628,4,405,708和4,311,782中已介绍。
最近在亚微平版印刷方法中的趋势是,作为光源深UV(波长200-300nm),优选使用高能(248nm)的KrF准分子激光器,而不是普通的UV,例如g线(波长436nm)或i线(波长365nm),为的是获得高的灵敏度和高的分辨率。所以,母体聚合物的吸光性应该在深UV的波长范围内,尤其在KrF准分子激光器的波长248nm处,被降低到最低。但是,由于t-bocPVP也含有苯基,它具有在短波长范围内显示出大的吸光性的突出缺点。
本发明人反复地进行深入的研究,其目的是为了开发用于亚微平版印刷方法的光刻胶,它除了具有为加工工艺所需要的高的玻璃化转变温度以外,还不吸收深紫外光(UV),从而获得以下发现:用脂环族化合物(N-乙烯基内酰胺)聚合而成的、被可与酸反应的基团保护的化学放大光刻胶在去保护后被转化成水性聚合物,并且通过使用弱碱性水溶液或仅仅使用纯水经过设计能够形成图象,从而显著改进形成图象的方法。
所以,本发明的主要目的是提供N-乙烯基内酰胺衍生物单体(其中乙烯基在3-位被各种保护基封闭),作为微平版印刷方法的光刻胶原料,能够满足高的灵敏度和高的分辨率。
本发明的另一目的是提供从该单体制备的聚合物。
本发明再一目的是提供用于光刻胶的聚合物。
本发明提供乙烯基内酰胺衍生物单体,其中乙烯基内酰胺在3-位被保护。通过让乙烯基内酰胺与强碱在低温下反应得到烯醇化物和向乙烯基内酰胺的3-位引入保护基,能够制备该单体。乙烯基内酰胺的具体实例包括N-乙烯基吡咯烷酮,N-乙烯基-4-丁基吡咯烷酮,N-乙烯基-4-丙基吡咯烷酮,N-乙烯基-4-乙基吡咯烷酮,N-乙烯基-4-甲基吡咯烷酮,N-乙烯基-4-甲基-5-乙基吡咯烷酮,N-乙烯基-4-甲基-5-丙基吡咯烷酮,N-乙烯基-5-甲基-5-乙基吡咯烷酮,N-乙烯基-5-丙基吡咯烷酮,N-乙烯基-5-丁基吡咯烷酮,N-乙烯基-5-哌啶酮,N-乙烯基-4-甲基哌啶酮,N-乙烯基-4-丙基哌啶酮,N-乙烯基-4-丁基哌啶酮,N-乙烯基-6-丁基哌啶酮,N-乙烯基己内酰胺,N-乙烯基-4-甲基己内酰胺,N-乙烯基-6-甲基己内酰胺,N-乙烯基-6-丙基己内酰胺,N-乙烯基-7-丁基己内酰胺和N-乙烯基酰亚胺。强碱可以例举叔丁基锂,氢化钠和正丁基锂。这一单体的制备能够在溶剂中进行,例子包括正戊烷,正己烷,正庚烷,环己烷,乙醚和四氢呋喃。作为保护基团的来源,能够使用氯甲酸叔丁酯,氯甲酸异丁酯,二(叔丁基)二碳酸酯,甲烷磺酰氯,甲磺酸酐,四氢吡喃,2-氯四氢呋喃,三甲基·氯化硅,4-甲氧基苄基氯,4-硝基苄基氯,二乙基·异丙基·氯化硅和叔-丁基·二甲基·氯化硅。

从这些通式可以看出,聚合物(II)是从一种上述单体得到的均聚物或通过聚合至少两种N-乙烯基内酰胺衍生物单体得到的共聚物。聚合物(III)是从N-乙烯基内酰胺衍生物和苯乙烯衍生物或乙烯基丙烯酸酯衍生物得到的共聚物。
在这些优选的聚合物当中,已发现聚3-(叔丁氧基羰基)-1-乙烯基-2-吡咯烷酮(下文称作“P(BCVP)”)是高度透明的,这已在试验中证实,其中1μm厚的膜在深UV范围内(200-300nm)显示出0.05或更低的吸光度。热解重量分析法(下面称作“TGA”)表明P(BCVP)在高达210℃的温度下是稳定的。在高于210℃的温度下,发生叔丁氧基羰基的快速去保护,产生2-甲基丙烯和CO2。在酸存在下,去保护分两步进行。首先,叔丁基在低温例如60℃下开始脱离聚合物骨架并在100℃下完全断裂。之后,在150℃产生CO2。这一事实告诉我们,P(BCVP)因其高的热分解温度和易在酸存在下于低温受到保护而具有非常优异的热性能。示差扫描量热法(下面称作“DSC”)表明,P(BCVP)的玻璃化转变温度在145-155℃范围内,这取决于它的分子量。
所有在3-位上受到保护的N-乙烯基内酰胺衍生物的聚合物都显示出优异的成膜性能。尤其是,P(BCVP)和聚3-(叔丁氧基羰基)-1-乙烯基-2-己内酰胺(下面称作“P(BCVC)”),它们都很好地溶于有机溶剂如二恶烷,氯仿,四氢呋喃,环己酮,2-乙氧基乙基乙酸酯,丙酮或甲基乙基酮。相反,去保护的聚合物很好地溶于碱的水溶液,如氢氧化钠或铵盐的溶液,在不溶于绝大多数的有机溶剂。在叔丁基的去保护之前或之后的这一选择性显影作用赋予聚合物优异的图象形成能力。在P(BCVP)的情况下,甚至只用纯水就能实现显影。对于包括P(BCVC)的其它聚合物,通过在弱碱溶液中使图象显影能够获得具有高分辨率的图象。在3-位上受到保护的乙烯基内酰胺衍生物的聚合物当中,发现P(BCVP)和P(BCVC)都具有高的灵敏度,例如1mJ/cm2,并显示出高的对比度。
代表性聚合物P(BCVP)和P(BCVC)在各种溶剂中的溶解度将随去保护而变化。结果总结在下表1中。
在酸的存在下,在这类聚合物的膜中于100℃或更低的温度下观察到叔丁基的去保护。形成精细图象的普通试验已证实本发明的聚合物能够用于高敏感性的化学放大光刻胶。聚合物的热分解行为的分析是借助于DSC(购自DuPont公司,MODEL 2100)和TGA在氮气气氛中以10℃/min的升温速度进行的。
