    • PURPOSE: A method for burying the contact hole of a semiconductor device is provided to increase adhesive strength between conducting layers and decrease the contact resistance by burying fully the contact hole in the process for forming metal wire. CONSTITUTION: After forming an oxide film(14) on a silicon substrate(11), the first contact hole and the second contact hole are formed on the silicon substrate(14) by etching the oxide film(14) selectively. The first titanium/titanium nitride layer(15) is formed on the whole structure including the contact holes by a chemical depositing vapor method. A tungsten layer is formed on the first titanium/titanium nitride layer(15). The tungsten layer is etched by a stop on titanium nitride etching method so as to form a tungsten plug(16A). A cavity is formed on the entrance of the contact holes by etching the tungsten layer. After the tungsten plug(16A) and the oxide film(14) are etched, an aluminum layer(20) is formed on the whole structure.
    • 目的:提供一种埋入半导体器件的接触孔的方法,以增加导电层之间的粘合强度,并通过在金属线形成工艺中完全埋入接触孔来降低接触电阻。 构成:在硅衬底(11)上形成氧化膜(14)之后,通过选择性地蚀刻氧化膜(14),在硅衬底(14)上形成第一接触孔和第二接触孔。 通过化学沉积蒸气法在包括接触孔的整个结构上形成第一钛/氮化钛层(15)。 在第一钛/氮化钛层(15)上形成钨层。 通过氮化钛蚀刻方法通过停止来蚀刻钨层,以形成钨丝塞(16A)。 通过蚀刻钨层在接触孔的入口上形成空腔。 在钨塞(16A)和氧化膜(14)被蚀刻之后,在整个结构上形成铝层(20)。

    • PURPOSE: A method for forming a contact of a semiconductor device is provided to simplify a fabrication process and reduce the manufacturing cost by depositing a tungsten layer as a barrier layer once. CONSTITUTION: A gate line is formed on a semiconductor substrate(200). A junction region is formed on both sides of the gate line. An interlayer dielectric(400) is formed on the semiconductor substrate. A contact hole for exposing an upper surface of the junction region is formed by removing selectively the interlayer dielectric. The first conductive layer(600) and the second conductive layer(800) are sequentially formed on the resultant structure. The third conductive layer(900) is formed on an upper surface of the second conductive layer by using a CVD method.
    • 目的:提供一种用于形成半导体器件的接触的方法,以通过沉积钨层作为阻挡层一次来简化制造工艺并降低制造成本。 构成:在半导体衬底(200)上形成栅极线。 在栅极线的两侧形成结区。 在半导体衬底上形成层间电介质(400)。 用于暴露接合区域的上表面的接触孔通过选择性地去除层间电介质而形成。 第一导电层(600)和第二导电层(800)依次形成在所得结构上。 第三导电层(900)通过使用CVD法形成在第二导电层的上表面上。

    • PURPOSE: A method for forming a capacitor is provided to be capable of preventing bridge between capacitors and degradation of a PSG(Phosphoric Silicate Glass) layer. CONSTITUTION: The first PSG layer(202) having a relatively heavily doped concentration and the second PSG layer(210) having a relatively lightly doped concentration are sequentially formed on a semiconductor substrate(200). After performing plasma treatment of the surface of the second PSG layer(210), an insulating pattern(212) is formed by selectively etching the second and first PSG layer(210,202). A conductive layer is formed on the resultant structure. A storage electrode(205) is formed to expose the insulating pattern(212) by selectively etching the conductive layer. Then, the insulating pattern(212) is removed.
    • 目的:提供一种用于形成电容器的方法,以能够防止电容器之间的桥接和PSG(磷酸硅酸盐玻璃)层的劣化。 构成:具有相对高掺杂浓度的第一PSG层(202)和具有相对轻掺杂浓度的第二PSG层(210)依次形成在半导体衬底(200)上。 在对第二PSG层(210)的表面进行等离子体处理之后,通过选择性蚀刻第二和第一PSG层(210,202)形成绝缘图案(212)。 在所得结构上形成导电层。 通过选择性地蚀刻导电层,形成存储电极(205)以露出绝缘图案(212)。 然后,去除绝缘图案(212)。
