Abstract
A method of manufacturing an electronic component having a capacitor element and a resistor element, in which such capacitor element and such resistor element are individually formed in the material layer (for example, a tantalum oxide film formed by the CVD process) by locally subjecting such material layer to different kinds of treatment, such as nitriding and oxidation, is provided. There is also provided a method of manufacturing a semiconductor device having a capacitor element and a resistor element, in which such capacitor element and such resistor element are individually formed in the same material layer by locally subjecting such material layer to different kinds of treatment. There is still also provided a semiconductor device having a capacitor element and a resistor element thus formed. According to the present invention, a material excellent as that for capacitor element and also suitable for other applications is used, and the material is effectively converted into other materials suitable for the capacitor element and resistor element, respectively. Thus the present invention can add value of such material, and allows a positive attitude to be taken in facility investment for such material and introduction of other similar new materials.
