摘要:
A method for fabricating a semiconductor device includes: the step (a) of forming a vibrating film on a predetermined region of each of a plurality of chips included in a semiconductor wafer; the step (b) of forming, on the semiconductor wafer, an intermediate film containing a sacrifice layer located on the vibrating film of each of the chips; and the step (c) of forming a fixed film on the intermediate film. This method further includes, after the step (c), the step (d) of subjecting the semiconductor wafer to blade dicing to separate the chips, and the step (e) of removing, by etching, the sacrifice layer to provide a cavity between the vibrating film and the fixed film.

A first element electrode and a second element electrode connected electrically to a semiconductor element on a substrate are formed, and then an insulating film is formed on the substrate including the element electrodes. Thereafter, a first opening for exposing the first element electrode and a second opening for exposing the second element electrode are formed on the insulating film. Then, a first external electrode connected to the first element electrode via the first opening is formed immediately above the first element electrode. Furthermore, a second external electrode and a connecting wire having one end connected to the second element electrode via the second opening and the other end connected to the second external electrode are formed on the insulating film.
