Abstract
A magnetoresistive reader having a sensor, current contacts with low parasitic resistance and a top shield with substantially planar topology is fabricated by first defining a stripe height back edge of the sensor. Next, a reader width of the sensor is defined. The current contacts are deposited to a thickness such that a top surface of the current contacts is substantially level with a top surface of the sensor. The top shield is deposited over the sensor and the current contacts. Defining the stripe height back edge prior to the reader width results in current contacts with low parasitic resistance and inhibits the formation of magnetic domains in the top shield.
