Abstract:
Method of forming embedded MRAM in interconnects using a metal hard mask process and the resulting device are provided. Embodiments include forming a first interlayer dielectric (ILD) layer including a first metal (Mx) level; forming a capping layer over the first ILD layer; forming magnetic tunnel junction (MTJ) structures formed in a second ILD over the first capping layer; forming a second metal (Mx+1) level in the second ILD layer; forming a second capping layer over the second ILD layer; and forming a third metal (Mx+2) level in a third ILD layer over the second capping layer.

Claim (Index 17):
A method comprising:\n forming a first interlayer dielectric (ILD) layer including a first metal (Mx) level; forming a capping layer over the first ILD layer; forming magnetic tunnel junction (MTJ) structures formed in a second ILD over the first capping layer; forming a second metal (Mx+1) level in the second ILD layer; forming a second capping layer over the second ILD layer; forming a third metal (Mx+2) level in a third ILD layer over the second capping layer; forming oxide spacers on sides of metal filled vias, the metal filled vias connecting the Mx level to the MTJ; forming copper (Cu) filled vias (Vx) connecting the Mx level to the Mx+1 level; and forming Cu filled vias (Vx+1) connecting the Mx+1 level to the Mx+2 level.
