Abstract:
Methods of forming planar RRAM and vertical RRAM with tip electrodes and the resulting devices are provided. Embodiments include forming a first metal oxide layer on a first dielectric layer; forming and patterning a mask layer over the first metal oxide layer; etching the first metal oxide through the mask layer to form openings for a first and second metal electrodes; removing the mask layer; forming the first and second metal electrodes in the openings; and forming a second metal oxide layer over the first and second metal electrodes, wherein the first and second metal electrodes are v-shaped in top view with tips of the first and second metal electrodes facing each other and a portion of the second metal oxide layer being formed between the tips of the first and second electrodes.

Claim (Index 17):
The method according to  claim 16 , further comprising:\n forming the first and second metal electrodes by sputter deposition, wherein the first and second metal electrodes are vertically stacked, wherein the first and second metal electrodes comprise titanium (Ti), titanium nitride (TiN), tantalum (Ta), tantalum nitride (TaN), aluminum (Al), copper (Cu), or aluminum copper silicon (AlCuSi), wherein the tips of the first and second v-shaped electrodes are self-aligned.
