摘要
A current perpendicular to plane (CPP) sensor having a sensor stack lead layer that is resistant to corrosion. The sensor includes a sensor stack having a capping layer at its top. A lead layer constructed of a non-corroding material such as Ru, Rh, Au or some similar material is formed over the capping layer. A magnetic shield material such a NiFe can then be deposited over the lead layer. The non-corroding lead material prevents the cap layer from corroding, preventing corrosion from causing parasitic resistance in the area in and around the lead and capping layers, thereby increasing sensor performance and reliability.
