Abstract: An adhesive layer (18) in which the same number of first and second layers (14,16) having conductivity are alternately laminated in order on a semiconductor substrate (10). A metal layer (24) is formed on the adhesive layer (18). The first layer (14) is composed of a material containing an element composing the semiconductor substrate (10). The second layer (16) has higher adhesion to the metal layer (24) than the first layer (14). The adhesive layer (18) has four or more layers including the first and second layers (14,16). Among the first layers (14) and the second layers (16) constituting the adhesive layer (18), excluding the second layer (16) contacting the metal layer (24), the first layer (14) contacting the semiconductor substrate (10) has the largest film thickness, and excluding the first layer (14) contacting the semiconductor substrate (10), the second layer (16) contacting the metal layer (24) has the largest film thickness.

Abstract: An MIM capacitor or an MIS capacitor in semiconductor devices is formed of a thin dielectric layer having a total film thickness less than 100-nm and including a high-dielectric-constant amorphous insulating film, high-breakdown-voltage amorphous films such as of SiO2, and high-dielectric-constant amorphous buffer films between an upper electrode and a lower electrode. The thin high-dielectric-constant amorphous insulation film is formed of a material having a property resistant to fracture although having properties of a large leakage current and a low breakdown voltage, to enhance reliability of the thin dielectric layer and to reduce the footprint thereof in the semiconductor device.
