Abstract
The present disclosure relates to semiconductor devices, specifically discloses a method and an apparatus for ion implantation. The above method may comprise: generating a particle beam that satisfies the implantation energy, wherein the particle beam comprises the target ion and the impurity particle; applying a first deflection magnetic field to the particle beam to deflect the particle beam, and applying a second deflection magnetic field to the deflected particle beam to cause a second deflection of the particle beam to separate the target ion from the impurity particle; and implanting the separated target ion into the semiconductor wafer.
