发明名称 Method of Manufacturing Metal Interconnection
摘要 A method of manufacturing a semiconductor is provided. A fist metal layer can be formed on a lower structural layer, and an interlayer metal dielectric (IMD) layer can be formed on the first metal layer. A sacrificial oxide layer can be formed on the IMD layer, and a planarization process can be performed on the sacrificial oxide layer and the IMD layer to substantially eliminate a height difference of the IMD layer.
