发明名称 Method for manufacturing semiconductor device by using dual damascene process and method for manufacturing article having communicating hole
摘要 A method for manufacturing a semiconductor device is provided, in which the lengths of a wiring trench and a via hole in a depth direction are easily controlled. A component having a first insulating film is prepared on a substrate, and a layer is disposed on the above-described first insulating film. A mold having a pattern is imprinted on the above-described layer so as to form a second insulating film having a wiring trench and a first via, the pattern corresponding to the wiring trench and the first via. Thereafter, the above-described first insulating film is etched by using the above-described second insulating film as a mask so as to form a second via, which is connected to the first via, in the first insulating film.
