    Abstract: A structure for patterning a polysilicon layer includes a TiN layer located above an amorphous silicon (a-Si) layer forming a TiN/a-Si stack. The TiN/a-Si stack is located above the polysilicon layer. The TiN layer serves as an ARC to reduce overexposure of the photoresist used to pattern the polysilicon layer, while the a-Si layer prevents contamination of the layer below the polysilicon layer.

    Abstract translation: 用于图案化多晶硅层的结构包括位于形成TiN / a-Si叠层的非晶硅(a-Si)层之上的TiN层。 TiN / a-Si堆叠位于多晶硅层的上方。 TiN层用作ARC以减少用于图案化多晶硅层的光致抗蚀剂的过度曝光,而a-Si层防止多晶硅层下面的层被污染。
