Abstract
A cantilever with spin valve sensor has been fabricated using photo and electron beam (EB) lithography, liftoff and bulk micromachining techniques. A four-point sensor configuration was used which has the advantages of neglecting resistance of lead electrodes and improving the signal-noise ratio (SNR) due to the reduction of total resistance of the magnetoresistive sensors.
