A method for manufacturing a metal-insulator-metal capacitor of a semiconductor device method for manufacturing a semiconductor device. In one example embodiment, a method for manufacturing a semiconductor device includes various steps. First, a logic metal and a capacitor lower metal is formed on a first insulating film that is formed on a semiconductor substrate. Next, a portion of the capacitor lower metal is selectively etched to a predetermined depth. Then, a second insulating film is formed over an entire upper surface of the logic metal, the first insulating film, and the capacitor lower metal. Next, a capacitor upper metal is formed on the second insulating film in a region corresponding to the etched portion of the capacitor lower metal. Finally, a third insulating film is formed on an entire upper surface of the second insulating film and the capacitor upper metal.
