    • A semiconductor device having a chamfered silicide layer and a manufacturing method of the same. The semiconductor device includes: a first insulation layer overlying a semiconductor substrate; gate structures including first conductive layer patterns formed on the first insulation layer, and second conductive layer patterns which are formed on the first conductive layer patterns, wherein the lower sides of the second conductive layer patterns are substantially perpendicular to the major surface of the semiconductor substrate and the upper sides of the second conductive layer patterns are chamfered; and a second insulation layer formed with a first width W on the second conductive layer patterns, wherein the sidewalls of the second insulation layer overhang the upper edges of the second conductive layer patterns. In the semiconductor device manufacture, in forming undercut regions which define the chamfered upper edges of the metal silicide layer patterns, isotropic dry etching is carried out, wherein the isotropic dry etching can be performed simultaneously with ashing of photoresist patterns, or immediately after the ashing process in the same chamber. In either case, after the ashing of the photoresist patterns, an isotropic wet etching can be carried out immediately after performing an existing stripping process, so as to form the undercut regions.

    • Methods of forming integrated circuit capacitors include the steps of forming a first electrically insulating layer having a conductive plug therein, on a semiconductor substrate, and then forming second and third electrically insulating layers of different materials on the first electrically insulating layer. A contact hole is then formed to extend through the second and third electrically insulating layers and expose the conductive plug. Next, a conductive layer is formed in the contact hole and on the third electrically insulating layer. A step is then performed to planarize the conductive layer to define a U-shaped electrode in the contact hole. The third electrically insulating layer is then etched-back to expose upper portions of outer sidewalls of the U-shaped electrode, using the second electrically insulating layer as an etch stop layer. However, the second electrically insulating layer is not removed but is left to act as a supporting layer for the U-shaped electrode. This second electrically insulating layer preferably comprises a composite of a nitride layer and an oxide layer. To increase the effective surface area of the U-shaped electrode, an HSG layer may also be formed on the inner and outer sidewalls of the U-shaped electrode.
    • 形成集成电路电容器的方法包括在半导体衬底上形成其中具有导电插塞的第一电绝缘层,然后在第一电绝缘层上形成不同材料的第二和第三电绝缘层的步骤。 然后形成接触孔以延伸穿过第二和第三电绝缘层并暴露导电插塞。 接下来,在接触孔和第三电绝缘层中形成导电层。 然后进行步骤以平坦化导电层以在接触孔中限定U形电极。 然后使用第二电绝缘层作为蚀刻停止层,蚀刻回第三电绝缘层以暴露U形电极的外侧壁的上部。 然而,第二电绝缘层不被去除,而是作为U形电极的支撑层。 该第二电绝缘层优选地包括氮化物层和氧化物层的复合物。 为了增加U形电极的有效表面积,也可以在U形电极的内侧壁和外侧壁上形成HSG层。
