Abstract: PURPOSE: A method for manufacturing a cell capacitor of a semiconductor memory is provided to maximize capacitance without increasing the height of a capacitor node. CONSTITUTION: An isolation region(2), a gate, a source/drain region, a plug and a bit line(11) are sequentially formed on a semiconductor substrate(1) as a pre-process for forming a capacitor. A nitride layer and the first oxide layer are sequentially formed on the resultant structure having the bit line. After the nitride layer and the first oxide layer are selectively etched to expose the plug connected to the drain region, a conductive material is filled to form a node contact. A photolithography process is performed regarding the resultant structure having the node contact to etch the first oxide layer in a region for a node, so that the node contact is protruded. After a polysilicon layer(24) is deposited on the structure of which a node contact(23A,23B) is protruded, the second oxide layer is deposited and etched-back to fill a region where the first oxide layer is etched and to expose the polysilicon layer formed on the first oxide layer and the node contact. After the exposed polysilicon layer is etched to form a node electrode, the first and second oxide layers are eliminated.
