Abstract: 비휘발성 메모리 장치의 제조 방법을 제공한다. 이 방법은 반도체기판 상에 하부 도전막을 형성하고, 그 결과물 상에 차례로 적층된 하부 희생막 패턴 및 상부 희생막 패턴을 형성한 후, 상부 및 하부 희생막 패턴의 측벽에 마스크 스페이서를 형성하는 단계를 포함한다. 이때, 상부 및 하부 희생막 패턴은 하부 도전막을 노출시키는 개구부를 갖는다. 또한, 상부 희생막 패턴은 하부 희생막 패턴에 대해 식각 선택성을 갖는 물질, 바람직하게는 실리콘 산화막으로 형성한다. 이때, 상부 희생막 패턴은 저온 화학 기상 증착의 방법으로 형성하는 것이 바람직하다. 그 결과, 열적 부담없이 마스크 스페이서의 높이를 증가시킬 수 있기 때문에, 워드 라인과 소오스 라인 사이의 쇼트를 예방할 수 있다.

Abstract: PURPOSE: A method for fabricating a non-volatile memory(NVM) device is provided to minimize thermal budget generated when a lower sacrificial layer is thickly formed, by forming an upper sacrificial layer made of a material like a silicon oxide layer having etch selectivity on the lower sacrificial layer. CONSTITUTION: A lower conductive layer is formed on a semiconductor substrate(100). A lower sacrificial layer pattern(135) having an opening exposing the lower conductive layer and an upper sacrificial layer pattern(145) are formed on the substrate including the lower conductive layer. A mask spacer(170) is formed on the sidewall of the upper and lower sacrificial layer patterns. The exposed lower conductive layer is etched by using the mask spacer and the upper sacrificial layer pattern as an etch mask so as to form a lower conductive layer pattern exposing the substrate. A plug conductive layer is formed to cover the front surface of the substrate including the lower conductive layer pattern. The plug conductive layer is planarization-etched until the lower sacrificial layer pattern is exposed, so that a source plug which fills a gap region between the mask spacers and is connected to the substrate is formed.

Abstract: PURPOSE: An isolation method of a semiconductor device is provided to be capable of preventing the unstrip phenomenon of a nitride layer by adding a dry etching process after carrying out a CMP(Chemical Mechanical Polishing) process. CONSTITUTION: A trench(104) is formed at the upper portion of a semiconductor substrate(101) by using the first nitride layer(103) as a mask. After forming the first isolating layer(105) on the resultant structure, the second nitride layer(107) is formed at the upper portion of the first insulating layer. The second isolating layer(108) having a predetermined thickness, is formed at the resultant structure for carrying out a gap-fill process at the trench. A planarization process is carried out at the resultant structure for exposing the second isolating layer and the second nitride layer. A dry etching process is carried out at the exposed second isolating layer and the second nitride layer for remaining the predetermined portion of the first nitride layer. Then, the first nitride layer is completely removed by carrying out an etching process.

Abstract: PURPOSE: A formation method of a contact plug is provided to reduce a manufacturing cost and to improve a through-put by forming a titanium nitride as a barrier metal by only a thermal treatment of a titanium at a nitrogen gas or an ammonia gas atmosphere without an extra titanium nitride formation. CONSTITUTION: An insulating layer(220) is formed on a semiconductor substrate(200) having an active region(210). An insulating pattern having a contact hole(230) is formed by partially etching the insulating layer(220) to expose the active region(210). A titanium(240) having a defined thickness is formed on the resultant structure. By annealing the titanium(240) at N2 or NH3 gas atmosphere, a titanium silicide layer(240a) on the active region(210) and a titanium nitride(240b) as a barrier metal on the titanium(240) are simultaneously formed, thereby simplifying a contact plug formation processing.
