求翻译：平坦剂中一般含有氮原子,通常是含氮的高分子聚合物,粘度较大,因此会依赖质量运输,这样在深而窄的孔内与加速剂、抑制剂的吸附竞争中没有优势,但在平坦和突出的表面,质量传输更有效。沟槽填充完成后,加速剂并不停止工作,继续促进铜的沉积,但吸附了平坦剂的地方电流会受到明显抑制,可以抑制铜过度的沉积。平坦剂通过在较密的细线条上方抑制铜的过度沉积从而获得较好的平坦化效果,保证了较小尺寸的图形不会被提前填满,有效地降低了镀层表面起伏。是什么意思？

Flat agents generally contain nitrogen atoms, usually nitrogen-containing polymers, viscosity, and therefore dependent on the quality of transport, so deep and narrow hole accelerator, inhibitor adsorption competition advantage. However, in the flat and prominent on the surface, mass transfer is mor

A flat, in general, contain nitrogen atoms are usually contain nitrogen in polymers, more viscous, so it will be dependent on quality transportation, so that the deep and narrow with the hole in the accelerator, inhibitor adsorption is not in competition, but on a flat surface and the surface qualit
