摘要: A binary mask layout design arranged hierarchically to include a plurality of levels is modified to include optical proximity effect corrections or phase shifting layers. This is accomplished by beginning at the lowest level of the hierarchy and modifying elements or cells in the design. Any modifications that are uniform to corresponding cells throughout the level are placed in the same level in the hierarchy. Any modifications that apply only to selected cells in the level are placed in a higher level in the hierarchy. The process is repeated for all levels in the hierarchy.

摘要: A process for designing and checking a mask layout is provided. A mask layout is generated from a binary mask layout design. An aerial image of the mask layout is then calculated using simulation software. The simulated aerial image is then compared to the binary mask layout design and modifications are made to the mask layout if necessary.
