发明名称 SEMICONDUCTOR DEVICE WHICH INCLUDES A CAPACITOR AND AN INTERCONNECTION FILM COUPLED TO EACH OTHER AND A MANUFACTURING METHOD THEREOF
摘要 A semiconductor device includes a semiconductor substrate and a capacitor which is disposed on a principal surface of the semiconductor substrate. The capacitor includes a lower electrode film disposed on the principal surface of the semiconductor substrate, a dielectric film disposed on the lower electrode and an upper electrode film disposed on the dielectric film. The semiconductor device further includes an interconnection film which includes a portion disposed on the upper electrode film so as to be electrically coupled to the upper electrode film. Directions of residual stresses of the upper electrode film coincide with directions of residual stresses of the portion of the interconnection film. Each of the upper electrode film and the interconnection film may include at least one of platinum and iridium. Also, there is provided a method of manufacturing the semiconductor device.
