摘要：
Techniques for forming a magnetic device are provided. In one aspect, a magnetic device includes a magnetic tunnel junction and a dielectric layer formed over at least a portion of the magnetic tunnel junction. The dielectric layer is configured to have an underlayer proximate to the magnetic tunnel junction, and an overlayer on a side of the underlayer opposite the magnetic tunnel junction. The magnetic device further includes a via hole running substantially vertically through the dielectric layer and being self-aligned with the magnetic tunnel junction.
