Title: Method of manufacturing semiconductor device employing insulating layer for giving three-dimensional shape in conductive layer
Inventor: LEE JOO-WON
IPC: H01L21/311
Filed: 2001-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor device wherein such a problem can be avoided that the side wall of an insulating layer, e.g. a mold, employed to form a three-dimensional storage electrode is tilted, resulting in the tilting of the side wall of the storage electrode. SOLUTION: This method includes a process of forming, on a semiconductor substrate 100, the insulating layer 200 whose characteristic etch rate is increased in the depthwise direction by changing one of evaporation variables, and a process of selectively etching the insulating layer to form a through hole which passes through the insulating layer and then forming a conductive layer in the through hole. By this method, an effective surface area increasing effect due to the increase in height of the three-dimensional structure of the storage electrode 400 can be maximized, and a step coverage defect can be prevented from being generated near a bottom of the periphery of the storage electrode when a dielectric layer or plate electrode is evaporated. Furthermore, the critical dimension of the bottom of the storage electrode can be increased and an additional margin for erroneous alignment between the storage electrode and a BC(buried contact) below the storage electrode can be secured. Eventually, a contact area between a lower part of the storage electrode and the BC can be increased to reduce the resistance.
