Abstract:
A method of manufacturing a magnetoresistive stack/structure comprising (a) etching through a second magnetic region to (i) provide sidewalls of the second magnetic region and (ii) expose a surface of a dielectric layer, (b) depositing a first encapsulation layer on the sidewalls of the second magnetic region and over a surface of the dielectric layer, (c) thereafter: (i) etching the first encapsulation layer which is disposed over the dielectric layer using a first etch process, and (ii) etching re-deposited material using a second etch process, wherein, after such etching, a portion of the first encapsulation layer remains on the sidewalls of the second magnetic region, (d) etching (i) through the dielectric layer to form a tunnel barrier and provide sidewalls thereof and (ii) etching the first magnetic region to provide sidewalls thereof, and (e) depositing a second encapsulation layer on the sidewalls of the tunnel barrier and first magnetic region.

Claim (Index 18):
A method of manufacturing a magnetoresistive stack/structure from: (i) a first magnetic region including one or more layers of magnetic material, (ii) an intermediate layer disposed over the first magnetic region, and (iii) a second magnetic region including one or more layers of magnetic material, wherein the second magnetic region is disposed over the intermediate layer, the method comprising:\n using a first etch process to etch through the second magnetic region to form one or more first sidewalls and expose an area of the intermediate layer, wherein the one or more first sidewalls and the area of the intermediate layer exposed by the first etch process form exposed surfaces, and wherein at least a portion of the exposed surfaces, after the first etch process, includes re-deposited material; depositing a first encapsulation layer on the exposed surfaces after the first etch process; and etching through the first encapsulation layer and the intermediate layer to form one or more second sidewalls; and depositing a second encapsulation layer on the one or more second sidewalls.
