    摘要: Provided is a method of fabricating a semiconductor device. The method includes providing a substrate, forming a photo acid generator (PAG) layer on the substrate, exposing the PAG layer to radiation, and forming a photoresist layer on the exposed PAG layer. The exposed PAG layer generates an acid. The acid decomposes a portion of the formed photoresist layer. In one embodiment, the PAG layer includes organic BARC. The decomposed portion of the photoresist layer may be used as a masking element.

    摘要: A method of patterning a semiconductor device including dividing a layout into more than one pattern. The method further includes depositing a film stack on a semiconductor substrate, depositing a hard mask on the film stack, and depositing a first photoresist on the hard mask. The method further includes patterning the first photoresist using a first pattern of the more than one pattern. The method further includes etching the hard mask to transfer a design of the first pattern of the more than one pattern to the hard mask. The method further includes depositing a second photoresist over the etched hard mask and patterning the second photoresist using a second pattern of the more than one pattern. The method further includes etching portions of the film stack exposed by a combination of the etched hard mask and the second photoresist.

    摘要: A method of forming a semiconductor structure includes forming a photoresist layer over a substrate. The photoresist layer includes a first material removable by a removal process. The first material at a guard band portion of the photoresist layer along an edge portion of the photoresist layer is converted to a second material. The second material is not removable by the removal process. Also, the first material at the edge portion of the photoresist layer is not converted to the second material. The guard band portion is farther from a periphery of the substrate than the edge portion. The removal process is performed to remove the first material after the conversion of the guard band portion.
