Capacitor and method of manufacturing the same

摘要

There is provided the capacitor which has a lower electrode (30) having a structure in which a first conductive layer (18, 20) containing a first metal, a second conductive layer (22) that is formed on the first conductive layer (18, 20) and made of a metal oxide of a second metal different from the first metal, and a third conductive layer (24) that is formed on the second conductive layer (22) and made of a third metal different from the first metal are formed sequentially; the dielectric layer (32) formed on the lower electrode (30); and the upper electrode (34) formed on the capacitor dielectric layer (32).
