Filed: 2000-06-28
Abstract: PURPOSE: A method for manufacturing a capacitor of a semiconductor device is provided to improve a step coverage characteristic, by forming a seed layer and a multiple oxide layer. CONSTITUTION: After an insulation layer(12) is formed on a semiconductor substrate(11) having a predetermined structure, a predetermined region of the insulation layer is etched to form a contact hole exposing a predetermined region of the semiconductor substrate. The inside of the contact hole is filled with a plug(14), a TiSix layer(15) and a diffusion barrier layer(16). A seed layer(17) is formed on the resultant structure. A multiple oxide layer of which the wet etch rate decreases as it goes from a lower layer to an upper layer, is formed on the resultant structure. After a dry etch process is performed regarding the multiple oxide layer to expose a lower contact hole portion, a wet etch process is carried out to form an oxide layer pattern of which the pattern width is greater in a lower portion than in an upper portion. After the first metal layer is formed by an electrochemical deposition method, the multiple oxide layer pattern is removed. After the exposed seed layer is eliminated, a dielectric layer and the second metal layer are formed on the resultant structure to form an upper electrode.
