MASKING APPARATUS FOR AN ION IMPLANTER |
摘要 |
A masking apparatus includes a mask positioned upstream of a target positioned for treatment with ions. The mask is sized relative to the target to cause a first half of the target to be treated with a selective treatment of ions through the mask and a second half of the target to be treated with a blanket treatment of ions unimpeded by the mask during a first time interval. The masking apparatus also includes a positioning mechanism to change a relative position of the mask and the target so that the second half of the target is treated with the selective treatment of ions and the first half of the target is treated with the blanket implant during a second time interval. An ion implanter having the masking apparatus is also provided.
