    摘要: A process for production of a semiconductor device having a multi-layer wiring of dual damascene structure in a low-dielectric constant interlayer insulating film. The process consists of the following steps. A first insulating film and a second insulating film are formed. A first to third mask forming layers are formed. The third mask forming layer is patterned so as to form the third mask for the wiring groove pattern. A resist mask of the connecting hole pattern is formed on the second mask forming layer including the third mask. The third mask and the second and first mask forming layers are etched, and the second insulating film is etched. The second mask of the wiring groove pattern is formed by using the third mask, and the connecting hole is made to the middle of the first insulating film. The first mask forming layer is etched by using the second mask, and the first mask of the wiring groove pattern is formed, and the first insulating film remaining at the bottom of the connecting hole is etched so as to make the connecting hole. The wiring groove is formed in the second insulating film by using the first or second mask.

    摘要: A method of forming an interconnection in a contact hole having a high aspect ratio, which is capable of certainly forming a barrier layer metal layer and burying a blanket W film in the contact hole without generation of any void. A Ti film is deposited in a contact hole by sputtering using a sputter system having a collimator plate and an oxidation preventive TiN thin film is deposited thereon by reactive sputtering using the same sputter system having the collimator plate. Next, a titanium silicide layer is formed by a first heat-treatment and a TiN film is formed by a second heat-treatment. Finally, a blanket W film is deposited by CVD to be buried in the contact hole.
