The method comprises providing a substrate and a patterned layer formed on the substrate, one or more overlay marks being formed on the patterned layer; performing a pre-film-formation overlay inspection using a bright field (BF) inspection tool to receive a pre-film-formation data on the one or more overlay marks on the patterned layer; forming one or more layers on the patterned layer; performing a post-film-formation overlay inspection using a dark field (DF) inspection tool to receive a post-film-formation data on the one or more overlay marks underlying the one or more layers; and determining whether the pre-film-formation data matches the post-film-formation data. | 06-25-2015 |
20150262815 | Method of Fabricating Semiconductor Integrated Circuit - A method of fabricating a semiconductor integrated circuit (IC) is disclosed. A first layer is deposited over a substrate. A plurality of mandrels is formed over the first layer. Guiding-spacers are formed along sidewalls of the mandrels. Then the mandrels are removed. A neutral layer (NL) and a block copolymer (BCP) layer are deposited over the first layer and the guiding-spacers. A anneal is applied to the BCP layer to form a first polymer nanostructure between the guiding-spacers and being surrounded by a second polymer nanostructure. The first polymer nanostructures locate at a same distance from the first layer. Polymer nano-blocks are formed by selectively etching the second polymer nanostructure and the NL. By using the polymer nano-blocks and the guiding spacer as etch masks, the first layer is etched to form openings. The substrate is etched through the openings to form substrate trench and substrate fin. | 09-17-2015 |
