Abstract

PURPOSE:To contrive to curtail ion implanting time by a method wherein a metal pattern is arranged on the margin of chips or at the neighborhood thereof of a wafer having the insulating surface, and ion implantation is performed. CONSTITUTION:Although dielectric breakdown originated from electric charge generated by ion implantation can be prevented by miniaturization of wafer size or by covering the surface of wafer with a conductor thin layer, but either of them results in rising of cost. Therefore a lattice type conductor pattern 2 is provided on the surface of the wafer 1, and electric charge stored in the wafer 1 is discharged to conductor nails coming in contact with the pattern 2 at the outside circumference thereof. When the pattern 2 is arranged along the marginal parts of the chips 1, no influence is applied to elements, and moreover when a mask is formed in the same mask with a metal mask pattern for transmission path, etc., cost can be reduced. By this constitution, even when ion implantation is performed with high speed, electric charge is not generated thereon, and the method thereof is extremely profitable for manufacture of magnetic bubble elements.
