Method of manufacturing semiconductor devices

摘要

A method of manufacturing a semiconductor device comprising a wiring formation step including: forming an interlayer insulating film composed of a boron nitride film having a dielectric constant of less than 4 on an (n)-th layer wiring, forming a hole and/or a trench in the interlayer insulating film, burying the hole and/or trench with a conductive material and forming an (n+1)-th layer wiring on the hole and/or trench.
