Abstract
A method of forming an integrated circuit includes forming first structures in a first portion of the integrated circuit and forming second structures, which are arranged more densely than the first structures, in a second portion. The first and second structures are defined by lithography processes using photomasks. At least one of the photomasks includes both openings in a first region for supporting the definition of the first structures and openings in a second region for supporting the definition of the second structures.
