Description

改善含碳和氧的氮化 钛层质量的方法
本发明涉及一种改善氮化钛(TiN)层质量的方法,TiN层通常用作钨的粘结层和敷铝过程中的扩散阻挡层,特别是涉及一种去除存在于TiN层中的碳和氧原子的方法。
通常,在半导体制造工艺中,TiN层广泛地用作扩散阻挡层和粘结层。制备TiN层的方法一般有两种,一种是物理气相沉积技术(以下简称PVD法),另一种是化学气相沉积技术(以下简称CVD法)。然而,人们通常采用CVD法来形成TiN层,因为该方法具有优良的台阶覆盖效果。
TiN层是通过热解诸如四二甲胺基钛(TDMAT)和四二乙胺基钛(TDEAT)等原材料得到的,所沉积的TiN层为多孔结构。
但是,由于采用热解方法得到的TiN层含有碳化物和氧化物,因此TiN层具有104μohm-cm或者更大的电阻率。同时,由于其多孔性,当TiN层暴露于空气中时,TiN层会吸收水份和氧气。在暴露约24小时的条件下,TiN层的电阻率是未经暴露的TiN层电阻率的3.5倍。TiN层的质量因此而恶化。
本发明的目的是提供一种采用等离子气体消除暴露于空气中的TiN层中的杂质,从而降低其电阻率的方法。
根据本发明的一个方面,提供一种制备TiN层的方法,其包括的步骤为:以原材料形成TiN层;将TiN层暴露于氢和氮等离子气体中。
根据本发明的另一个方面,提供一种制备TiN层的方法,其包括的步骤为:以原材料形成TiN层;将TiN层暴露于氢等离子气体中。
下文将描述本发明的一个实施例。
首先,采用CVD方法,通过热解TDMAT和TDEAT沉积TiN层。然后,利用氮气和氢气对TiN层进行初次等离子处理。也就是说,TiN层暴露于氮气和氢气中。
在优选实施例中,初次等离子处理的条件如下:
1)氮气量:100-500标准立方厘米
2)氢气量:100-500标准立方厘米
3)温度:200-500℃
4)压力:0.5-5乇
5)射频(RF)功率:200-700瓦
6)处理时间:10-60秒
对于TiN层的初次等离子处理是在合成TiN层的工作室中或者紧随TiN层暴露于空气中而放入另一工作室中完成的,没有时间上的延迟。
对TiN层进行初次处理后,采用氮气进行第二次等离子处理。
在优选实施例中,第二次等离子处理的条件如下:
1)氮气量:100-500标准立方厘米
3)温度:200-500℃
4)压力:0.5-5乇
5)射频(RF)功率:200-700瓦
6)处理时间:10-60秒
在初次等离子处理中,激活的氢离子渗透进入TiN层,使TiN层中的-C≡N,=C=N-和=C=O根的键断裂,从而与分裂出来的碳和氧原子发生化合。另一方面,由化合形成的副产物包括CH4和H2O,这些副产物将逸出TiN层。
此外,被激发的氮离子阻止了TiN层对存在于工作室中的氧离子的吸收,并占据逸出的CH4和H2O所形成的空位。
在进行了初次等离子处理的TiN层上再进行第二次等离子处理,使氮原子最大限度地占据TiN层。
等离子处理的结果使钛和氮相结合。因此,经过等离子处理的TiN层的密度要高于未经过等离处理的TiN层,并且能够获得具有较低的电阻率的TiN层。
表1描述了TiN层的电阻率随其形成后暴露于空气的时间的变化。
表(1)TiN层的电阻率
暴露于空气的时间            电阻率(μohm-cm)
   未经等离子处理 经过等离子处理
   0小时     19706     2714
   22小时     70044     3922
   47小时     93376     4249
   73小时     112009     4444
初次等离子处理:           第二次等离子处理:
1)温度:450℃               1)温度:450℃
2)压力:2乇                 2)压力:2乇
3)射频功率:350瓦           3)射频功率:350瓦
4)氢气:200标准立方厘米     4)氮气:300标准立方厘米
5)氮气:300标准立方厘米     5)时间:30秒
6)时间:30秒
在表1中,第二次等离子处理除了只采用300标准立方厘米的氮气等离子体外,与初次等离子处理的条件相同。
从表1中可以看出TiN层的电阻率有相当显著的下降。
此外,表2列出了TiN层的应力变化,表3列出了TiN层中氧原子和碳原子的减少情况。
表(2)TiN层的应力情况

应力变化比率(%)           44%             15%
表(3)TiN层的成份
 未经等离子处理(原子百分数)   经过等离子处理(原子百分数)
 Ti       37       45
 C       29       18
 N       21       27
 O       13       10
下文将描述本发明的另一实施例。
对通过热解TDMAT和TDEAT沉积而成的TiN层进行只包含氮气和氢气中的一种等离子气体的等离子处理。在此,所有处理条件与上文所述实施例相同。
当然,根据TiN层的特点,可以只采用两步等离子处理中的一步。
如上所述,本发明通过消除TiN层中的杂质和减少TiN层中的孔隙,获得了降低TiN层的电阻率的效果。因此,本发明可以提高TiN层的电学稳定性。
虽然为了说明的目的公开了本发明的优选实施例,但是,本专业技术领域的人员应当理解,在不偏离本发明权利要求书的范围和精神的前提下,可以作出各种改进、添加和替代。
