– ~ 80-100 mm periodicity, radially out from center of wafer • Edge Bead – residual ridge in resist at edge of wafer – can be up to 20-30 times the nominal thickness of the resist – radius on wafer edge greatly reduces the edge bead height – non-circular wafers greatly increase the …

Semiconductor Wafer Edge Analysis/6 Figure 3 shows an example of an edge measurement of a thin bonded wafer. This demonstrates defects leading up to and within the transition region of a rounded wafer edge. The upper plot shows the roughness calculated with a high pass filter (cutoff filter) of 250 µm over a distance of 6,000 µm.

ago.2 Cutting-edge wafer fabrication, the manufacturing of semiconductors, is a highly concentrated market in terms of companies and geography. Currently, only TSMC in Taiwan and Samsung in South Korea successfully operate cutting-edge process nodes at 7nm and below, which are necessary for many modern logic sem-
