    摘要: A semiconductor device includes a low dielectric constant film having a copper interconnection formed therein, a silicon oxide film arranged above the low dielectric constant film, a surface protection film arranged above the silicon oxide film, a sealing ring formed to surround a circuit forming region, and a groove portion formed outside the sealing ring when viewed two-dimensionally. The groove portion is formed such that its bottom portion is located above the low dielectric constant film and such that the bottom portion is located below an upper end of the copper interconnection.

    摘要: A method of manufacturing a semiconductor device is obtained which is capable of evading generation of a short circuit between wirings in an upper wiring layer even if a part of an upper surface of an FSG film is exposed by variations in a production step. After a USG film (4) is deposited to a thickness of 1 &mgr;m over an entire surface of an FSG film (3), the USG film (4) is polished and removed by a thickness of 900 nm from an upper surface thereof by the CMP method. At this time, a part of an upper surface of the FSG film (3) is exposed by variations in a production step. Next, the surface of the interlayer dielectric film (50) is cleaned with a cleaning liquid whose etching rate to the FSG film (3) and etching rate to the USG film (5) are substantially the same. Such a cleaning liquid may be, for example, an ammonia hydrogen peroxide mixture of NH4OH:H2O2:H2O=1:1:20. The structure shown in FIG. 5 is dipped in the above-mentioned ammonia hydrogen peroxide mixture for 60 seconds to clean the surface of the interlayer dielectric film (50).

    摘要: Implemented is a method of manufacturing a contact structure having a combination of formation of a buried wiring and that of a low dielectric constant interlayer insulating film in which a connecting hole to be formed in a low dielectric constant interlayer insulating film does not turn into an abnormal shape. A fourth interlayer insulating film 11 is formed on an upper surface of a third interlayer insulating film 10. Next, patterning for a wiring trench and a connecting hole is carried out into the fourth interlayer insulating film 11 and the third interlayer insulating film 10, respectively. Then, a pattern of the connecting hole is first formed in a third low dielectric constant interlayer insulating film 9. Thereafter, a second interlayer insulating film 8 exposed in the pattern is removed and a pattern of the wiring trench is formed in the third interlayer insulating film 10. Subsequently, second and third low dielectric constant interlayer insulating films 7 and 9 are etched, and the wiring trench and the connecting hole are formed at the same time. Thus, a photoresist can be formed again without the second and third low dielectric constant interlayer insulating films 7 and 9 exposed, and an abnormal shape is generated in the connecting hole with difficulty.
