发明名称 Method for manufacturing a capacitor for a semiconductor device
摘要 A method for manufacturing a capacitor for a semiconductor device, which includes the steps of forming a first conductive layer on a semiconductor substrate, forming a first pattern by patterning the first conductive layer, sequentially forming a second conductive layer and a first material layer on the entire surface of the resultant structure, forming a spacer on the sidewall of the second conductive layer by anisotropic-etching the first material layer, forming a second pattern by partially etching the second conductive layer and the first pattern, using the spacer as an etching mask, forming a third conductive layer on the entire surface of the resultant structure, forming a cylindrical storage electrode by anisotropic-etching the third conductive layer, and removing the spacer.
