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 13):
A method comprising:\n forming a first metal oxide layer on a first dielectric layer; forming and patterning a first mask layer over the first metal oxide layer; etching the first metal oxide through the first mask layer to form a first opening for a first metal electrode; forming the first metal electrode in the first opening; forming and patterning a second mask layer over the first metal oxide layer; etching the first metal oxide through the second mask layer to form a second opening for a second metal electrode; forming the second metal electrode in the second opening; and forming a second metal oxide layer over the first and second metal electrodes, wherein the first and second metal electrodes comprise different metals and 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.
