METHOD FOR FABRICATING SEMICONDUCTOR DEVICE

A method for fabricating a semiconductor device, the method including forming a mold structure on a substrate such that the mold structure includes alternately and repeatedly stacked interlayer insulating films and sacrificial films; forming a channel hole passing through the mold structure; forming a vertical channel structure within the channel hole; exposing a surface of the interlayer insulating films by removing the sacrificial films; forming an aluminum oxide film along a surface of the interlayer insulating films; forming a continuous film on the aluminum oxide film; and nitriding the continuous film to form a TiN film. 种用于制造半导体器件的方法，所述方法包括：在衬底上形成模制结构，使得模制结构包括交替且重复地层叠的层间绝缘膜和牺牲膜；形成穿过模制结构的沟道孔；在沟道孔内形成垂直沟道结构；通过去除牺牲膜来暴露出层间绝缘膜的表面；沿层间绝缘膜的表面形成氧化铝膜；在氧化铝膜上形成连续膜；以及对连续膜进行氮化以形成TiN膜。
