Abstract
A method of manufacturing a magnetoresistive device may comprise forming a first magnetic region, an intermediate region, and a second magnetic region of a magnetoresistive stack above a via; removing at least a portion of the second magnetic region using a first etch; removing at least a portion of the intermediate region and at least a portion of the first magnetic region using a second etch; removing at least a portion of material redeposited on the magnetoresistive stack using a third etch; and rendering at least a portion of the redeposited material remaining on the magnetoresistive stack electrically non-conductive.
