The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. An interconnection structure comprising an interlevel insulating film, made of organic-containing silicon dioxide, between lower- and upper-level metal interconnects,
wherein a phenyl group, bonded to a silicon atom, is introduced into silicon dioxide in the organic-containing silicon dioxide.
2. An interconnection structure comprising:
lower-level metal interconnects;
a first insulating film formed over the lower-level metal interconnects and mainly composed of organic-containing silicon dioxide, in which silicon dioxide contains an organic component;
a second insulating film formed over the first insulating film and mainly composed of an organic component;
upper-level metal interconnects formed in the second insulating film; and
contacts formed in the first insulating film to inter-connect the lower-and upper-level metal interconnects.
3. The interconnection structure of claim 2, wherein a phenyl group, bonded to a silicon atom, is introduced into silicon dioxide in the organic-containing silicon dioxide.
4. An interconnection structure comprising:
metal interconnects;
a first insulating film, which is formed over the metal interconnects to cover the metal interconnects and to leave grooves between the metal interconnects and is mainly composed of organic-containing silicon dioxide, in which silicon dioxide contains an organic component;
a second insulating film, which is formed on the first insulating film to fill in the grooves and has a relative di-electric constant lower than that of the first insulating film; and
a third insulating film, which is formed over the second insulating film and has a composition different from that of the second insulating film.
5. The interconnection structure of claim 4, wherein the second insulating film is mainly composed of an organic component, and
wherein the third insulating film is mainly composed of organic-containing silicon dioxide, in which silicon dioxide contains an organic component.
6. The interconnection structure of claim 5, wherein a phenyl group, bonded to a silicon atom, is introduced into silicon dioxide in the organic-containing silicon dioxide.
