    • Disclosed herein is a method of manufacturing semiconductor devices. The method includes the steps of forming a gate oxide film, a polysilicon film and a nitride film on a semiconductor substrate, and patterning the gate oxide film, the polysilicon film and the nitride film to form poly gates, forming a spacer at the side of the poly gate, forming a sacrifice nitride film on the entire surface, and then forming an interlayer insulation film on the entire surface, polishing the sacrifice nitride film formed on the interlayer insulation film and the poly gates so that the nitride film is exposed, removing top portions of the sacrifice nitride film while removing the nitride film, forming an insulation film spacer at the side exposed through removal of the nitride film, and filling a portion from which the sacrifice oxide film is removed with an insulation film, and forming the tungsten gates in portions from which the nitride films are moved.
    • 这里公开了半导体器件的制造方法。 该方法包括在半导体衬底上形成栅极氧化膜,多晶硅膜和氮化物膜的步骤,以及对栅极氧化膜,多晶硅膜和氮化物膜进行构图以形成多晶硅栅极,在 在整个表面上形成牺牲氮化物膜,然后在整个表面上形成层间绝缘膜,研磨在层间绝缘膜和多晶硅栅上形成的牺牲氮化物膜,使得氮化物膜露出,去除 牺牲氮化物膜的顶部,同时去除氮化物膜,在通过去除氮化物膜暴露的一侧形成绝缘膜间隔物,并且用绝缘膜填充去除牺牲氧化物膜的部分,并形成钨 栅极在其中移动氮化物膜的部分中。
