Abstract:
1. A method for tuning an ion implanter system having multiple beam-line elements, the method comprising: generating, from a beam setup database, a tuning table having a plurality of entries, wherein each entry comprises a combination of settings for the multiple beam-line elements that are likely to produce a desired beam output; adjusting the multiple beam-line element settings in a coordinated manner by applying one or more of the plurality of entries to the multiple beam-line elements until an actual beam output within an acceptable range of the desired beam output is achieved; and upon exhausting the plurality of the entries in the tuning table without bringing the actual beam output within the acceptable range of the desired beam output, further adjusting the multiple beam-line elements in a coordinated manner to search for a new combination of settings that produces the desired beam output, thereby accumulating an additional entry for the tuning table.
