Original Abstract Submitted
The present disclosure relates to a magneto-resistive random access memory (MRAM) cell having an extended upper electrode, and a method of formation. In some embodiments, the MRAM cell has a magnetic tunnel junction (MTJ) arranged over a conductive lower electrode. A conductive upper electrode is arranged over the magnetic tunnel junction. Below the conductive lower electrode is a first conductive via structure in a first dielectric layer. Below the conductive via structure is a discrete conductive jumper structure in a second dielectric layer. A dielectric body of a third dielectric material that is different from the first dielectric material and the second dielectric material extends vertical from the first dielectric layer at least partially into the second dielectric layer.
