摘要: 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.
