Estimating the term…
Magnetic sensors with effectively shaped side shields and their fabrication processes are provided. One such sensor includes a substrate, a sensor stack disposed on the substrate and having a stripe height, where the sensor stack further includes a front edge disposed at an air bearing surface (ABS) of the magnetic sensor, a back edge opposite of the front edge, and two side edges, and a side shield adjacent to each of the two side edges of the sensor stack, each side shield having a side shield height defined as a distance from the ABS to a back edge of the side shields, where the side shield height is greater than the stripe height, and where substantially no residue from materials used to form the side shield are disposed at the back edge of the sensor stack.
A magnetic sensor comprising:
