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.

摘要: A first species selectively dopes a workpiece to form a first doped region. In one embodiment, a selective implant is performed using a mask with apertures. A soft mask is applied to the first doped region. A second species is implanted into the workpiece to form a second implanted region. The soft mask blocks a portion of the second species. Then the soft mask is removed. The first species and second species may be opposite conductivities such that one is p-type and the other is n-type.

摘要: Glitches during ion implantation of a workpiece, such as a solar cell, can be compensated for. In one instance, a workpiece is implanted during a first pass at a first speed. This first pass results in a region of uneven dose in the workpiece. The workpiece is then implanted during a second pass at a second speed. This second speed is different from the first speed. The second speed may correspond to the entire workpiece or just the region of uneven dose in the workpiece.
