摘要:
A grid for minimizing effects of ion divergence in plasma ion implant. The plasma grid is made of a flat plate having a plurality of holes, wherein the holes are arranged in a plurality of rows and a plurality of columns thereby forming beamlets of ions that diverge in one direction. A mask is used to form the implanted shapes on the wafer, wherein the holes in the mask are oriented orthogonally to the direction of beamlet divergence.
