Abstract
I studied the effect of wafer topography on the chemical mechanical polishing (CMP) process. This was done by first designing test structures. A mask set of these structures was then designed and fabricated. Wafers were patterned with the test mask and then were polished. The result was that a pattern dependency was seen on the wafers. The polishing process was effected by the surface topography.
