Description

微粒发生少的含Mn铜合金溅射靶
技术领域
本发明涉及微粒发生少的含Mn铜合金溅射靶,其能够同时制造半导体器件布线的扩散防止膜和种子膜。
背景技术
一般公知有半导体器件的布线,如图2的半导体器件的布线部剖面图所示,在表面具有槽2的被覆有SiO2等绝缘膜的基板(以下称为基板)1的表面上,将Ta金属膜3作为扩散防止膜形成,在该Ta金属膜3之上形成纯铜制种子膜4,还在该纯铜制种子膜4的表面上通过镀敷等形成布线薄膜5。
作为上述扩散防止膜公知的Ta金属膜3,由于Ta金属本身的价格昂贵,所以近些年来对替代Ta金属膜的低价的具有扩散防止作用的金属膜进行了研究,如图1的半导体器件的布线剖面图所示,如果通过使用CuMn铜合金靶进行溅射,在具有槽2的被覆有SiO2等绝缘膜的基板1的表面上直接形成含Mn铜合金膜,之后,对形成的含Mn铜合金膜进行热处理,则上述含Mn铜合金膜7中所含的Mn和基板的SiO2等绝缘膜反应生成Mn和Si的复合氧化物含有层6,上述Mn和Si的复合氧化物含有层6作为扩散防止膜发挥作用,因此,能够省略高价的Ta金属膜的形成,并且,上述含Mn铜合金膜7能够作为种子膜使用,这些含Mn铜合金膜和Mn及Si的复合氧化物含有层的研究十分盛行。(参照非专利文献1、2)

非专利文献2:IITC发表摘要(2005年6月8日)
但是,在通过使用含有上述Mn:0.6-30质量%,余量由Cu及杂质构成的成分组成的含Mn铜合金靶进行溅射而形成含Mn铜合金靶薄膜时,在溅射时,存在微粒发生多的缺点,这成为成品率低下成本上升的原因。
发明内容
因此,发明者们为了得到溅射时微粒发生少的含Mn铜合金溅射靶而进行了研究。其结果是得出如下研究结果:
(a)在通过使用含有Mn:0.6-30质量%,余量由Cu及杂质构成的成分组成的含Mn铜合金靶进行溅射而形成含Mn铜合金靶膜时,上述含Mn铜合金靶中所含的杂质的量越少就越能抑制微粒的发生,并且在作为该杂质而含有的金属系杂质合计为40ppm以下极少,还含有氧为10ppm以下、氮为5ppm以下、氢为5ppm以下、碳为10ppm以下很少时,在溅射时发生的微粒数骤减。
(b)此外,含Mn铜合金靶为结晶粒度:30μm以下的再结晶等轴组织时,能够进一步抑制微粒的发生。
基于上述研究结果,产生了本发明。
(1)一种微粒发生少的含Mn铜合金溅射靶,其由铜合金构成,该铜合金具有含有Mn:0.6-30质量%,余量由Cu以及杂质构成的组成,上述杂质中,金属类杂质合计为40ppm以下,并且将氧限定为10ppm以下,将氮限定为5ppm以下,将氢限定为5ppm以下,将碳限定为10ppm以下。
(2)根据上述(1)所述的微粒发生少的含Mn铜合金溅射靶,其特征在于,所述微粒发生少的含Mn铜合金溅射靶具有结晶粒度:30μm以下的再结晶等轴组织。
在制造本发明的含Mn铜合金溅射靶时,在纯度:99.9999%以上的高纯度电解铜中添加纯度:99.9%以上的高纯度电解Mn,在惰性气体气氛中在高纯度石墨模内进行高频溶解,由此制作含Mn铜合金铸锭,对该铸锭进行热加工,热加工结束温度为450℃以上,从而制作热加工材,还跟据需要对该热加工材进行水冷,之后除去该热加工材的表面厚度为0.2mm以上的范围,接着,反复进行冷加工和退火,最后进行退火,由此得到本发明的含Mn铜合金溅射靶。
接着,对本发明的含Mn铜合金溅射靶的成分组成的限定理由加以说明。
(a)Mn
Mn成分具有使含Mn铜合金溅射靶的晶粒微细化,有进一步抑制晶粒成长的效果,还有在所形成的含Mn铜合金膜和基板边界部分形成作为扩散防止膜起作用的Mn和Si的复合氧化物含有层的作用,但其含量低于0.6质量%则不能得到希望的效果,另一方面,含有超过30质量%时,靶的导热率下降在溅射中靶的温度上升,并且,使所得到的含Mn铜合金膜的抵抗增加,因此在作为半导体器件的布线使用时,不为优选。因此,本发明含Mn铜合金溅射靶中所含的Mn为0.6-30质量%,更优选为1.0~20质量%。
(b)杂质
在使用含Mn铜合金靶进行溅射时发生的微粒数,越减少含Mn铜合金靶中所含的杂质的含量,越能抑制微粒的发生,Fe、Ni、Cr、Si、Pb、Co、Mg、Zn等的金属类杂质合计超过40ppm,还有氧、氮、氢、碳等非金属类杂质分别为氧超过10ppm、氮超过5ppm、氢超过5ppm、碳超过10ppm时微粒发生数急剧增加。因此,将本发明的含Mn铜合金溅射靶中所含的杂质定为:金属类杂质合计为40ppm以下,并且氧为10ppm以下、氮为5ppm以下、氢为5ppm以下、碳为10ppm以下。
使用本发明的含Mn铜合金溅射靶制作的含Mn铜合金膜,因为能够同时形成代替Ta金属膜的扩散防止层和种子膜,所以能够省略高价的Ta金属膜的形成,因此能够降低成本,还因为能够将溅射时发生的微粒的发生抑制为很少,因此能够实现降低半导体器件等的制造成本的优异的效果。

具体实施方式
下面通过实施例具体地说明本发明的含Mn铜合金溅射靶。
准备纯度:99.9999质量%以上的高纯度电解铜,还准备纯度:99.9质量%以上的电解锰,将该高纯度电解铜和不同量的电解锰在Ar气气氛中的高纯度石墨模内高频溶解,溶解中通过吹入气体或添加微量元素调整杂质的含量,将如此得到的熔液在碳铸模中铸造,对所得的铸锭进行热锻,结束温度为450℃以上,热锻结束后进行水冷,随后,对热锻材的整个表面进行面磨削,除去1.5mm的厚度。
之后,根据需要对进行过面切削的热锻材进行冷轧,其后退火,反复进行该冷轧和退火,最后进行再结晶退火,再对得到的退火材的表面进行车床加工,制作具有外径:300mm×厚度5mm的尺寸,具有表1所示的成分组成的本发明靶1-8和比较靶1-6。
还可以准备市场出售的电解铜,在该市场出售的电解铜中在Ar气体气氛中在高纯度石墨模内高频溶解预先准备的电解锰,将所得到的熔液在碳铸模中进行铸造制作铸锭,对所得到的铸锭进行热锻,结束温度为450℃以上,热锻结束后进行水冷,其后对热锻材的整体表面进行磨削,磨去厚度:1.5mm的深度。
其后,对经过表面研削的热锻材进行冷轧,之后进行退火,反复进行该冷轧和退火,最终进行去应变退火,对所得到的去应变退火材的表面再进行车床加工,制成具有外径:300mm×厚度5mm的尺寸,具有表1所示成分组成的现有靶。切断这些本发明靶1-8、比较靶1-6和现有靶,测定剖面的平均晶粒直径,其结果在表1中显示。
此外,准备纯铝制垫板,使本发明靶1-8、比较靶1-6和现有靶与重合,在温度500℃实施热静水压处理,由此将本发明靶1-8、比较靶1-6和现有靶与纯铝制垫板接合而制作带有垫板的靶。
利用将本发明靶1-8、比较靶1-6和现有靶与纯铝制垫板用热静水压处理接合而得到的带有垫板的靶,以如下的高出力条件,在被覆有SiO2等绝缘膜的基板之上形成薄膜。由微粒计数器测定此时发生的微粒数,其结果在表1中显示。
高出力条件:
电源:交流方式
功率:4KW
气氛气体组成:Ar
溅射气压:1Pa
靶和基体的距离:80mm
溅射时间:5分钟
[表1]

从表1显示的结果可知,在本发明靶1-8中,金属类杂质在40ppm以下,并且氧限定为10ppm以下,氮限定为5ppm以下,氢限定为5ppm以下,碳限定为10ppm以下,由此与杂质多的现有靶相比微粒发生少。但是,比较例1因为靶的纯度高,所以靶的平均晶粒直径过大,微粒发生变多,另一方面,比较靶2-6杂质过多,微粒发生变多。
