A method of fabricating a magnetic head including a CPP read head sensor. The CPP sensor includes a layered sensor stack including a free magnetic layer, a tunnel barrier layer, a pinned magnetic layer and an antiferromagnetic layer. An ion milling process is used to perform a partial depth material removal to establish the back wall of the sensor stack, where the antiferromagnetic layer is not milled through to create the back wall of the sensor stack. ELGs are fabricated during said ion milling process, and in an embodiment the ELGs are disposed at a same level as the tunnel barrier layer and are coplanar therewith.
