    摘要: A magnetoresistive film is formed on the surface of a lower electrode layer in a method of making a current-perpendicular-to-the-plane structure magnetoresistive element. The magnetoresistive film includes a lower portion and an upper portion overlaid on the lower portion. The lower portion includes at least a pinned magnetic layer. The upper portion includes at least a free magnetic layer. A pair of domain control magnetic layers is formed to sandwich the magnetoresistive film. An insulator film is formed to cover over the domain control magnetic layers. The upper portion is subjected to an etching process. The domain control magnetic layers are reliably prevented from being removed during the etching process. Accordingly, the domain control magnetic layers are allowed to reliably sandwich the upper portion of the magnetoresistive film in the aforementioned manner.
