Abstract:
1. A method of manufacturing a semiconductor device, comprising: forming a first insulating film above a semiconductor substrate that includes a circuit region and a scribe region; forming a first via pattern, that continuously surrounds the circuit region, in the first insulating film; forming a first conductive material in the first via pattern; forming a second insulating film above the first via pattern and the first insulating film; forming a first interconnection pattern in the second insulating film; forming a second conductive material, that continuously contacts the first conductive material, in the first interconnection pattern; forming a third insulating film above the first interconnection pattern and the second insulating film; forming a second interconnection pattern in the third insulating film; forming a third conductive material, that continuously contacts the second conductive material, in the second interconnection pattern; forming an A after forming the A covering a sidewall of the groove, a bottom of the groove and the third insulating film with a fourth insulating film, the fourth insulating film including Si and C as principal components; and forming a fifth insulating film over the fourth insulating film.
