    • PURPOSE: A semiconductor device is provided to prevent opening failure created in a process that a first contact hole is filled with conductive materials by forming the first contact hole in the inner side of a flattered liner insulating layer and a first interlayer insulating film. CONSTITUTION: A first gate electrode(129) and a second electrode(130) are located on a substrate(100). A first spacer and a second spacer are located on the sidewall of the first electrode and the second electrode. A first contact hole(115) which exposes a constant area of a silicide film(110) is formed within a liner insulating layer(112) and a first interlayer insulating film(113). A first sub contact plug(117) which interlinks a high concentration impurity region(109) and a metal wiring(128) is formed within the first contact hole. A second interlayer insulating film(118) and an etching stopping layer(119) are successively located on the first interlayer insulating film.
    • 目的:提供一种半导体器件,用于防止在第一接触孔填充有导电材料的过程中产生的开路故障,该方法是在平坦化的衬里绝缘层和第一层间绝缘膜的内侧形成第一接触孔。 构成:第一栅电极(129)和第二电极(130)位于衬底(100)上。 第一间隔物和第二间隔物位于第一电极和第二电极的侧壁上。 在衬垫绝缘层(112)和第一层间绝缘膜(113)内形成露出硅化物膜(110)的恒定面积的第一接触孔(115)。 在第一接触孔内形成有互连高浓度杂质区(109)和金属布线(128)的第一副接触插塞(117)。 第一层间绝缘膜(118)和蚀刻停止层(119)依次位于第一层间绝缘膜上。
