Abstract: During the fabrication of masks for integrated circuits, the polygons on the pattern generator must be covered by a preferably as small as possible number of rectangles. In this paper we present a fast and simple heuristic, based on Voronoi diagrams, which covers arbitrary polygons without acute interior angles by rectangles in time 0(nlog+r), where n is the number of edges of the polygon and r is the number, in practice close to n, of rectangles produced, and they suggest that the algorithm is near-optimal.
