    • An improved capacitor that is less susceptible to the depletion effect and methods for providing the same. The capacitor comprises a first and second electrode and an insulating layer interposed therebetween. The first electrode includes a bulk layer comprising n-doped polysilicon. The first electrode also includes an interface layer extending from a first surface of the bulk layer to the insulating layer. The interface layer is heavily doped with phosphorus so that the depletion region of the first electrode is confined substantially within the interface layer. The method of forming the interface layer comprises depositing a layer of hexamethldisilazane (HMDS) material over the first surface of the bulk layer so that HMDS molecules of the HMDS material chemically bond to the first surface of the bulk layer. The method further comprises annealing the layer of HMDS material in a phosphine ambient so as to replace CH3 methyl groups with PH3 molecules. The interface layer is then passivated in a nitrogen ambient having a reduced temperature so as to reduce the number of dangling silicon bonds of the lower electrode in a manner that results in reduced thermal damage to neighboring circuit elements.
    • 对消耗效应不太敏感的改进的电容器及其提供方法。 电容器包括第一和第二电极以及介于它们之间的绝缘层。 第一电极包括包含n掺杂多晶硅的体层。 第一电极还包括从主体层的第一表面延伸到绝缘层的界面层。 界面层用磷重掺杂,使得第一电极的耗尽区基本上被限制在界面层内。 形成界面层的方法包括在本体层的第一表面上沉积一层六甲基二硅氮烷(HMDS)材料,使得HMDS材料的HMDS分子化学键合到本体层的第一表面。 该方法还包括在磷化氢环境中退火HMDS材料层,以便用PH 3分子取代CH 3 3甲基。 然后在具有降低的温度的氮气环境中钝化界面层,以便以导致对相邻电路元件的热损伤降低的方式减少下电极的悬挂硅键的数量。
