ABSTRACT:
A method of making a read sensor while protecting it from electrostatic discharge (ESD) damage involves forming a severable shunt during the formation of the read sensor. The method may include forming a resist layer over a plurality of read sensor layers; performing lithography with use of a mask to form the resist layer into a patterned resist which exposes left and right side regions over the read sensor layers as well as a shunt region; etching, with the patterned resist in place, to remove materials in the left and right side regions and in the shunt region; and depositing, with the patterned resist in place, left and right hard bias and lead layers in the left and right side regions, respectively, and in the shunt region for forming a severable shunt which electrically couples the left and right hard bias and lead layers together for ESD protection.
