Method for providing a structure in magnetic recording transducer

摘要

A method provides a structure in a magnetic recording transducer. The structure resides on an underlayer. The method includes providing a protective layer and providing layer(s) for the structure. The protective layer covers a field region but exposes a device region in which the structure is to reside. A first portion of the layer(s) reside in the device region, while a second portion of the layer(s) reside in the field region. The method also includes removing the second portion of the layer(s) using an over-removal condition. The underlayer is covered by a remaining portion of the protective layer after the removing step is completed. The method also includes removing the remaining portion of the protective layer. An underlayer removal rate is substantially less than a protective layer during the step of removing of the protective layer.
