Disclosed herein is a method of manufacturing a semiconductor device. The method includes forming an etch-stop film on a semiconductor substrate in which a predetermined structure is formed, and then forming an interlayer insulating film. The method also includes etching a predetermined region of the interlayer insulating film, and then stopping the etch process at the etch-stop film, to form a damascene pattern. The method employs an etch-stop film made of a material having a low dielectric constant. Accordingly, an increase in the capacitance due to an etch-stop film formed of the existing material having a high dielectric constant can be prevented. It is therefore possible to prevent a reduction of RC delay and also to accelerate the operating speed of devices.

A stereo speaker system including: a speaker unit having a plurality of speakers which output audio; and a filter unit selectively receiving low frequency components of the outputted audio. The filter unit eliminates the received low frequency components to decrease back pressure on the speakers. Thus, the phenomenon of air-loading caused by back-pressure is removed and the low frequency characteristic of stereo speakers is improved by activating the vibration of a vibrating plate.
