ABSTRACT:
Semiconductor devices having a capacitor and methods of manufacturing the same are disclosed. A disclosed semiconductor device includes a semiconductor substrate; a lower interconnection line on the substrate; an upper interconnection line electrically connected to a first portion of the lower interconnection line; a first metal layer electrically connected to a second portion of the lower interconnection line; a capacitor insulating layer on the first metal layer; and a second metal layer on the capacitor insulating layer, wherein the first metal layer, the capacitor insulating layer and the second metal layer form a capacitor
