Patent ID: 7361913

Claim:
A stationary-beam ion implanter operative to perform an ion implantation in a semiconductor wafer, comprising: a source of a stationary, planar ion beam; a plurality of beamline components operative to steer the ion beam along a normal beam path as determined by respective first values of respective operating parameters of the beamline components; an end station operative to mechanically scan the wafer across the normal beam path; and control circuitry operative, in response to detecting a glitch in the ion beam during the implantation pass, to: substantially immediately alter at least one operating parameter of at least one of the beamline components to a respective second value effective to direct the ion beam away from the normal beam path and thereby cease implantation of the wafer at an implantation transition location on the wafer; while the ion beam is directed away from the normal beam path, move the wafer to an implantation-resuming position in which the implantation transition location on the wafer lies directly on the normal path of the ion beam; and as the wafer reaches the implantation-resuming position, substantially immediately return the at least one operating parameter of the at least one beamline component to its respective first value to thereby direct the ion beam along the normal beam path and resume ion implantation at the implantation transition location on the wafer.
