TMR reader without DLC capping structure
Embodiments herein generally relate to TMR readers and methods for their manufacture. The embodiments discussed herein disclose TMR readers that utilize a structure that avoids use of the DLC layer over the sensor structure and over the hard bias layer. The capping structure over the sensor structure functions as both a protective layer for the sensor structure and a CMP stop layer. The hard bias capping structure functions as both a protective structure for the hard bias layer and as a CMP stop layer. The capping structures that are free of DLC reduce the formation of notches in the second shield layer so that second shield layer is substantially flat.
