Semiconductor device having multiple conductive layers and the method of manufacturing the semiconductor device

摘要

A semiconductor device having multiple conductive layers which are satisfactorily connected to one another is disclosed. The multiple conductive layers are respectively insulated by insulation layers and are formed on the semiconductor substrate where circuit elements are formed. Each multiple conductive layer is connected through contact holes having the same depth and at least one conductive layer is connected to the first conductive layer thereunder through an additional conductive layer formed at the same time that the second conductive layer is formed.
