Abstract
Systems and method include providing a non-volatile random access memory (NVRAM) stack including a plurality of layers. The plurality of layers includes a dielectric layer and a metal layer. The metal layer of the NVRAM stack is patterned. The patterning causes damage to lateral side portions of the dielectric layer. The lateral portions of the dielectric layer are repaired by depositing dielectric material on the lateral side portions of the dielectric layer.
Claims24
A method comprising:
- providing a non-volatile random access memory (NVRAM) stack including a plurality of layers, wherein the plurality of layers includes a dielectric layer and a metal layer;
- patterning the metal layer of the NVRAM stack, wherein the patterning causes damage to lateral side portions of the dielectric layer;
- and
- repairing the lateral portions of the dielectric layer by depositing dielectric material on the lateral side portions of the dielectric layer.
