A sputter deposition apparatus and method includes perimeter magnets oriented an angle relative to the plane of the sputter target, either by magnetizing or by physically orienting the magnets at the chosen angle. The resulting magnetic flux extends radially outward, away from the central axis of the target, toward and beyond the target perimeter. This causes the return path of the flux to pass over the target surface more parallel to the plane of its sputtering surface. This spreads sputter erosion over a greater area of the target surface and mitigates development of sputtering grooves. Since target erosion is more uniform, more target material is used for sputter deposition, deterring waste. Each target can be used longer before the target material is penetrated, resulting in fewer target replacement cycles for a given volume of workpiece coating, raising the deposition chamber capacity factor.
