摘要:
There is disclosed an Al alloy composite tube for refrigerant passages, made by extruding, or extruding and drawing a two-layer composite pipe obtained by shrink-fit of a tubular Al alloy inner material to the inside of a tubular Al alloy core, or a three-layer composite pipe obtained by shrink-fit of the two-layer composite pipe to the inside of a tubular Al alloy outer material; and a method for producing the same. This Al alloy composite tube for refrigerant passages causes less blisters at the interface between an inner pipe and an outer pipe, and can prevent debonding of the inner pipe.

摘要:
As a method for constituting a pre-metal interlayer insulating film, such method is considered as forming a CVD silicon oxide-based insulating film having good filling properties of a silicon oxide film by ozone TEOS, reflowing the film at high temperatures to planarize it, then stacking a silicon oxide film having good CMP scratch resistance by plasma TEOS, and, further, planarizing it by CMP. However, it was made clear that, in a process for forming a contact hole, crack in the pre-metal interlayer insulating film is exposed in the contact hole, into which barrier metal intrudes to cause short-circuit defects.In the present invention, in the pre-metal process, after forming the ozone TEOS film over an etch stop film, the ozone TEOS film is once etched back so as to expose the etch stop film over a gate structure, and, after that, a plasma TEOS film is formed over the remaining ozone TEOS film, and then the plasma TEOS film is planarized by CMP.
