    摘要: Ions having a high energy is implanted using a mask of a stacked film consisting of a film formed from an amorphous material and a film formed from a metal having a large mass number.In this way, penetration of ions can be prohibited by a mask having a far smaller thickness than that of the conventional mask. Thus ions having a high energy can be implanted with a very high accuracy.
