摘要： A multi-layer gate stack structure of a field-effect transistor device is fabricated by providing a gate electrode layer stack with a polysilicon layer, a transition metal interface layer, a nitride barrier layer and then a metal layer on a gate dielectric, wherein the transition metal is titanium, tantalum or cobalt. Patterning the gate electrode layer stack comprises a step of patterning the metal layer and the barrier layer with an etch stop on the surface of the interface layer. Exposed portions of the interface layer are removed and the remaining portions are pulled back from the sidewalls of the gate stack structure leaving divots extending along the sidewalls of the gate stack structure between the barrier layer and the polysilicon layer. A nitride liner encapsulating the metal layer, the barrier layer and the interface layer fills the divots left by the pulled-back interface layer. The nitride liner is opened before the polysilicon layer is patterned. As the requirement for an overetch into the polysilicon layer during the etch of the metal layer, the barrier layer and the interface layer is omitted, the height of the polysilicon layer can be reduced. The aspect ration of the gate stack structure is improved, the feasibility of pattern and fill processes enhanced and the range of an angle under which implants can be performed is extended.
摘要翻译：通过提供具有多晶硅层，过渡金属界面层，氮化物阻挡层，然后在栅极电介质上的金属层的栅电极层堆叠来制造场效应晶体管器件的多层栅极堆叠结构，其中，过渡金属是钛，钽或钴。对栅电极层堆叠进行图案化包括在界面层的表面上用蚀刻阻挡层图案化金属层和阻挡层的步骤。界面层的暴露部分被去除，其余的部分从栅极叠层结构的侧壁被拉回，留下在阻挡层和多晶硅层之间的栅堆叠结构的侧壁延伸的纹理。封装金属层，阻挡层和界面层的氮化物衬垫填充由拉回界面层留下的凹坑。在将多晶硅层图案化之前打开氮化物衬垫。作为在金属层的蚀刻期间进行多晶硅层的蚀刻的要求，省略了阻挡层和界面层，可以降低多晶硅层的高度。提高了栅极堆叠结构的方面，增加了图案和填充过程的可行性，并且延长了可以进行植入的角度范围。
