Abstract:
A layout file for an integrated circuit has drawn geometries. Variable fill geometries are added to local areas based on densities of the drawn geometries in windows associated with the local areas and on the global density of all the drawn geometries in the layout file. Each window has a separate local area associated with it. The densities of the variable fill geometries in the local areas are not all equal. Densities of the fill geometries are higher in local areas associated with windows having lower densities of the drawn geometries, and for lower values of the global density. The layout file is stored in a computer-readable medium which may be used to produce a photomask for manufacturing an integrated circuit.

Claim (Index 9):
A method of producing an integrated circuit layout, comprising:\n computing a first local density of drawn geometries for a physical layer in a first window for the integrated circuit, the drawn geometries corresponding to functional structures of the physical layer directly electrically coupled to active components of the integrated circuit; generating first variable fill geometries in a first fill portion of a first local area associated with the first window, the first fill portion being free of the drawn geometries, the first variable fill geometries corresponding to first fill structures of the physical layer, separate from the functional structures, the first variable fill geometries having a first fill density defined by a ratio of a first fill structure area in a fill portion of the first local area divided by an area of the fill portion of the first local area; computing a second local density of the drawn geometries for the physical layer in a second window for the integrated circuit, different from the first window, the second local density being higher than the first local density; generating second variable fill geometries in a second fill portion of a second local area associated with the second window, the second fill portion being free of the drawn geometries, the second variable fill geometries having a second fill density defined by a ratio of a second fill structure area in a fill portion of the second local area divided by an area of the fill portion of the second local, the second fill density being lower than the first fill density; and storing a layout file including the first variable fill geometries and the second variable fill geometries on a computer-readable data storage medium in a form suitable for producing a photomask corresponding to the physical layer.
