    摘要: A metallization structure having a substantially flat surface can be formed on a semiconductor substrate by forming first and second insulating layers on the substrate. The second insulating layer is selectively removed to form grooves therein. Then, a metallic material layer is conformably formed. The metallic layer has grooves corresponding to the grooves of the second insulating layer. A flowable polymer is applied to the surface of the resultant structure to form a layer having a flat surface. The polymer layer and the metallic layer are sequentially ion-etched to expose the second insulating layer. Thus, the metallization structure constituted by the remaining metallic layer and the second insulating layer is formed to have a flat surface.

    摘要: A method for planarizing the surface of an insulation layer deposited on a first interconnection layer to allow a second interconnection layer deposited thereon without causing a breakage of the second interconnection layer. This method is characterized in that at least two insulation films, different in etching characteristics each other, are first formed on the first interconnection layer, and then a resist layer is deposited on the second insulating film. Subsequently, a portion of the resist layer is etched to expose the top surface of the second insulating film, and the second insulating film is selectively and anisotropically etched using the remaining resist layer as a mask. After removing the first insulating film and the remaining resist mark, a third insulating film is deposited to a thickness sufficient to make flat the surface thereof.
