Semiconductor device and method of manufacturing the same

摘要

A semiconductor device including an MIM capacitor is provided. A first metal wiring layer is patterned together with a first hard mask member and forms a lower capacitor electrode. A second metal wiring layer is formed on the first metal wiring layer with a capacitor insulating film therebetween and is patterned together with a protection layer and a second hard mask member which remains under the first hard mask member. The second metal wiring layer forms a plurality of upper capacitor electrodes. A third metal wiring layer connected with the first or second metal wiring layer is patterned on an insulating film. The third metal wiring layer includes a connection with a plug wiring member provided within a first or second contact hole.
