Abstract
A method is provided for manufacturing a capacitor with a unique sturcture. The capacitor includes a structure formed in the dielectric layer and the etching stop layer and forming a contact window, a conducting material-adhering layer formed on a portion of the etching stop layer neighboring to the contact window, a first conducting layer filling in the contact window and upwardly extended to form a generally cross-sectionally modified T-shaped structure with a rough top surface, and a rugged conducting layer formed inside the first conducting layer and on the conducting material-adhering layer. This method significantly increases the density and intensity of the capacitor.
