Abstract
Magnetic sensors with effectively shaped side shields and their fabrication processes are provided. One such process includes depositing sensor materials on a substrate, shaping the sensor materials to form a stripe height of the magnetic sensor, shaping the sensor materials to form a track width of the magnetic sensor, depositing side shield materials on the shaped sensor materials, shaping the side shield materials such that a resulting side shield extends further than the stripe height, depositing an insulator layer on the shaped side shield materials, and shaping the insulator layer.
