Abstract:
A sputtering method for depositing a film comprising the steps of:forming a plurality of magnetic fluxes on a target;forming an electric field between the target and a substrate;conveying the substrate during film deposition while reciprocating the plurality of magnetic fluxes at least in the direction of conveying the substrate; andcontrolling (i) the speed v of conveying the substrate, (ii) the distance L in the direction of conveying the substrate between two adjacent points where the magnetic field of the plurality of magnetic fluxes and the electric field cross each other at a right angle, and (iii) the period T of a reciprocating motion of the plurality of magnetic fluxes so as to satisfy the formula L/v=(n+1/2)T, wherein n is in accordance with the formula z-1/16<n<z+1/16, and z is an integer equal to or greater than 0.
