    摘要: PROBLEM TO BE SOLVED: To provide a method and apparatus that gives a local and global matching for designing a feature structure onto a semiconductor wafer surface.SOLUTION: A semiconductor manufacturing method comprises forming a leveling guard ring defining an interior area. After forming the guard ring in an area affected by local features' elevation differences, photoresist is applied to provide a uniform height over the whole guard ring interior area, resulting in manufacture of uniform devices. One or more devices are fabricated in the region, and two or more devices are fabricated in the interior area in a common centroid layout. The guard ring is formed on at least one particular layer for a particular processing step. In addition, a plurality of guard rings enclosing respective arrays of the devices are arranged with a space between them so as not to be close to each other. Thus, both local and global matching is achieved.
