| 摘 要： | 本文采用激光诱导荧光技术(LIF)来研究抛光参数对化学机械抛光加工区液膜厚度的影响.研究表明,抛光液膜厚度随着抛光载荷的增加而减少,减小的趋势随抛光载荷的提高而减缓.同时液膜厚度随着抛光速度的增加而变大.通过抛光参数的变化对抛光液液膜厚度影响的分析,为改善CMP加工工艺提供理论性的依据.

| Abstract: | Laser inducement fluorescence (LIF) is used to study the effect of polishing parameters on slurry film thickness. The study indicates that the slurry layer decreases with increasing polishing load and increases with increasing polishing speed. However, the current is slow down with the increase polishing load. By analyzing the effects of CMP process parameters involving load and speed on slurry film, the CMP process is controllable in theoretical principle. |
