초록
Sufficient removal rate with adequate selectivity to realize the pattern mask of tetra-ethyl ortho-silicate (TEOS) film for the vertical sidewall angle were obtained by chemical mechanical polishing (CMP) with commercial silica slurry as a function of pH variation. The changes of X-ray diffraction pattern and dielectric constant by CMP process were negligible.
