Disclosed are: (i) a method for forming an intermetal dielectric layer between metal wirings using a low-k dielectric material, and (ii) a semiconductor device with an intermetal dielectric layer comprising a low-k dielectric material. The method comprises the steps of: (a) forming a metal layer on a semiconductor substrate; (b) forming a plurality of metal wiring patterns by etching the metal layer selectively; (c) forming a first dielectric layer on the substrate and the plurality of metal wiring patterns; (d) forming a low-k dielectric layer on the first dielectric layer, the low-k dielectric layer having a lower dielectric constant than the first dielectric layer; and (e) forming a second dielectric layer on the low-k dielectric layer.
