Abstract
The semiconductor device has a wiring M, an interlayer insulating film ILformed on the wiring M, and two wirings Mformed on the interlayer insulating film IL, and the wiring Mis connected to the wiring Mby a conductor layer PGformed in the interlayer insulating film IL. A recess CCis formed on the upper surface ILof the interlayer insulating film IL, and the recess CCis defined by a side surface Sconnected to the upper surface ILand a side surface Sconnected to the side surface S, and the side surface Sis inclined so that the width WCof the recess CCdecreases in the direction from the upper surface ILof the interlayer insulating film ILtoward the upper surface ILof the interlayer insulating film IL
