Title: Semiconductor device
Inventor: KATO TAKUYA
IPC: H01L27/108
Filed: 1985-07-05
Abstract: PURPOSE:To make higher density, by employing as a capacitor a three-layer structure consisting of a silicon oxide layer, a metal oxide layer, and a metal nitride layer containing a constituting element of metal or a metal nitride layer containing oxygen atoms and a constituting element of metal. CONSTITUTION:A three-layer capacitor film consisting of a silicon oxide film 5, a niobium oxide film 6a, and a niobium nitride film 7a is formed on a P-type silicon substrate 1. Even if polycrystalline silicon is employed for an opposing electrode 8, it is the niobium nitride film 7a that the polycrystalline silicon contacts, so the silicide reaction of the polycrystalline silicon can be suppressed. In this way, since the leak current can be reduced and the silicon oxide film 5 and the niobium nitride film 7a can be formed thin, the dielectric constant of the niobium oxide film 6a and thus the capacitance per unit area can be made large.
