Abstract
The magnetic characteristics of a magnetoresistive device are improved by rendering magnetic debris non-magnetic during processing operations. Further improvement is realized by annealing the partially- or fully-formed device in the presence of a magnetic field in order to eliminate or stabilize magnetic micro-pinning sites or other magnetic abnormalities within the magnetoresistive stack for the device. Such improvement in magnetic characteristics decreases deviation in switching characteristics in arrays of such magnetoresistive devices such as those present in MRAMs.
