    摘要: An immersion lithography process is described as follows. A photoresist layer and a protective layer are sequentially formed on a material layer, and then an immersion exposure step is performed to define an exposed portion and an unexposed portion in the photoresist layer. A solubilization step is conducted to solubilize the protective layer on the exposed portion of the photoresist layer, and then a development step is conducted to remove the exposed portion of the photoresist layer and the protective layer thereon. Since the photoresist layer is covered with the protective layer, the chemicals in the photoresist layer do not diffuse into the immersion liquid to cause contamination. The protective layer can be patterned simultaneously in the development step, and no extra step is required to remove the protective layer. Therefore, the whole lithography process is not complicated.

    摘要: The present invention is directed to a method for planarizing BARC layer in dual damascene process. For forming a dual damascene interconnect structure, by use of the present invention, a planar topography of the BARC layer is achieved by chemical mechanical polishing. The present invention applies a low temperature to bake the coated BARC layer before BARC material cross-links and induces the anti-reflective characteristic. Then, the BARC layer is planarized by chemical mechanical polishing. Next, a high temperature baking of the BARC layer is provided before coating the photoresist, so formation of the BARC layer is controlled with minimized variation in surface level and has the antireflective characteristic. Thus, the profile distortion on the via and the critical dimension control for the via are improved by patterning the via on a planar and an anti-reflective surface.

    摘要: In accordance with the present invention, a method for forming a via-first dual damascene interconnect structure by using gap-filling material whose thickness is easily controlled by a developer is provided. The essential part of the present invention is the application of gap-filling materials such as novolak, PHS, acrylate, methacrylate, and COMA to fill vias. Filling vias with these materials can get a greater planar topography for trench patterning due to its excellent gap-filling capacity, protect the bottom of vias from damage during the trench etch, and prevent the fence problem by using a developer to control its thickness in vias.
