Method for manufacturing a magnetoresistive sensor using simultaneously formed hard bias and electrical lapping guide
Abstract:
A method for manufacturing a magnetic sensor using an electrical lapping guide deposited and patterned simultaneously with a hard bias structure of the sensor material. The method includes depositing a sensor material, and patterning and ion milling the sensor material to define a track width of the sensor. A magnetic, hard bias material is then deposited and a second patterning and ion milling process is performed to simultaneously define the back edge of an electrical lapping guide and a back edge of the sensor.
