    • A method of forming a capacitor structure includes the steps of forming a conductive layer on a microelectronic substrate, and forming a first hemispherical grained silicon layer on the conductive layer opposite the substrate. A protective layer is formed on the hemispherical grained silicon layer. The protective layer, the first hemispherical grained silicon layer, and the conductive layer are then patterned so that portions of the microelectronic substrate are exposed adjacent the patterned conductive layer. A second hemispherical grained silicon layer is formed on the surface of the protective layer opposite the first hemispherical grained silicon layer, on sidewalls of the patterned conductive layer, and on the exposed portions of the microelectronic substrate. Portions of the second hemispherical grained silicon layer are removed from the exposed portions of the microelectronic substrate, and the patterned protective layer is then removed.
    • 一种形成电容器结构的方法包括以下步骤:在微电子衬底上形成导电层,并在与衬底相对的导电层上形成第一半球晶粒硅层。 在半球状粒状硅层上形成保护层。 然后对保护层,第一半球形晶粒硅层和导电层进行构图,使得微电子衬底的部分暴露在图案化导电层附近。 在保护层的与第一半球状粒状硅层相对的表面上,在图案化的导电层的侧壁上,以及微电子衬底的露出部分上形成第二半球状粒状硅层。 从微电子衬底的暴露部分去除第二半球形硅层的一部分,然后去除图案化的保护层。

    • An apparatus for fabricating a semiconductor device having cooling jackets for preventing a gas from being exuded in a reaction chamber, thereby minimizing the generation of contaminating particles. The apparatus includes a reaction chamber having four cooling jackets respectively mounted on a first side wall adjacent to a wafer transfer chamber, a second side wall opposite to the first side wall, an upper wall and a bottom wall. A gate valve is disposed between the reaction chamber and the wafer transfer chamber and has a fifth cooling jacket. While fabricating a polysilicon film using the above apparatus, a pressure of a cassette chamber is controlled to be less than about 0.05 mtorr. Alternatively, a pressure of a cooling chamber and the wafer transfer are both controlled to be less than about 1.0 &mgr;torr.
    • 一种用于制造具有用于防止气体渗透到反应室中的冷却夹套的半导体器件的装置,从而使污染颗粒的产生最小化。 该装置包括具有分别安装在与晶片传送室相邻的第一侧壁上的四个冷却夹套的反应室,与第一侧壁相对的第二侧壁,上壁和底壁。 闸阀设置在反应室和晶片传送室之间,并具有第五冷却套。 在使用上述装置制造多晶硅膜的同时,将盒室的压力控制在小于约0.05毫托。 或者,冷却室和晶片转移的压力都被控制为小于约1.0倍。
