ABSTRACT:
Methods, systems, and media to improve the manufacturability of cells and structures within cells of an integrated circuit are disclosed. Embodiments comprise a method of arranging programmable cells, routing the programmable cells, analyzing the cell arrangement and interconnect wiring for manufacturing improvement opportunities, and modifying the programmable cell structures to incorporate the manufacturing improvements. In some embodiments, wires are spread to prevent shorting. In other embodiments, the reliability of contacts and vias is improved by adding additional metallization to the areas surrounding the contacts and vias, or by adding redundant contacts and vias. In one embodiment, a series of manufacturing improvements are made to integrated circuit cells in an iterative fashion.
