Abstract
Described is a method of manufacturing a sputtering target or backing plate for a sputtering target that minimizes metal waste and reduces manufacturing steps. The target or backing plate is made from a substantially circular metal blank by progressively deforming circumferential bands until the blank is in the shape of a sputtering target or backing plate. The target and backing plate so produced are also described.
