摘要: Methods to form complementary implant regions in a workpiece are disclosed. A mask may be aligned with respect to implanted or doped regions on the workpiece. The mask also may be aligned with respect to surface modifications on the workpiece, such as deposits or etched regions. A masking material also may be deposited on the implanted regions using the mask. The workpiece may be a solar cell.
