Abstract
본 발명은 반도체소자의 캐패시터 제조방법에 관한 것으로, 반도체 기판 상부에 소자분리절연막, 게이트전극 및 불순물 확산영역을 순차적으로 형성하고 그 상부에 하부절연층을 형성한 다음, 마스크를 이용하여 다수의 홈을 형성하고 단차피복비가 우수한 도전층을 전체표면상부에 형성한 다음, 저장전극마스크를 이용한 식각공정으로 상기 도전층을 식각함으로써 표면적이 증가된 저장전극을 형성하고, 후공정에서 전체표면상부에 유전체막과 플레이트전극을 순차적으로 형성하여 고집적화에 충분한 정전용량을 갖는 캐패시터를 형성함으로써 반도체소자의 고집적화를 가능하게 하고 이에 따른 반도체소자의 신뢰성을 향상시킬 수 있는 기술이다.The present invention relates to a method of manufacturing a capacitor of a semiconductor device, in which a device isolation insulating film, a gate electrode, and an impurity diffusion region are sequentially formed on a semiconductor substrate, and a lower insulating layer is formed thereon, and then a plurality of grooves are formed by using a mask. And forming a conductive layer having excellent step coverage ratio on the entire surface, and then etching the conductive layer by an etching process using a storage electrode mask to form a storage electrode having an increased surface area, and a dielectric on the entire surface in a later process. By forming a film and a plate electrode sequentially to form a capacitor having a capacitance sufficient for high integration, it is possible to achieve high integration of the semiconductor device and thereby improve the reliability of the semiconductor device.
