Abstract:
Provided is a method for forming a dual damascene structure of a semiconductor element which is as follows: (a) first and second insulation layers are sequentially formed on a substrate; (b) a resist mask with a pattern for forming a via-hole is formed on the second insulation layer; (c) a via-hole is formed to a bottom of the first insulation layer; (d) a hard mask layer is formed on the via-hole and the second insulation layer by using a spin-on-coating method; (e) a resist mask with a pattern for forming a trench hole is formed on the hard mask layer; (f) a first trench hole is formed to a bottom of the second insulation layer through the resist mask; (g) each of portions of a hard mask layer, which are formed on the via-hole and the second insulation layer, are removed; (h) a portion of the second insulation layer between a top corner of the via-hole (via top corner) and a bottom corner of the first trench hole (trench bottom corner) is removed to form a second trench hole; (i) a remaining hard mask layer, which is formed on the via-hole and the second insulation layer, is removed; and (j) the via-hole and the second trench hole are buried with a conductive material, such that an upper interconnection is formed.
