发明名称 Self-aligned cross point resistor memory array
摘要 A method of fabricating resistor memory array includes preparing a silicon substrate; depositing a bottom electrode, a sacrificial layer, and a hard mask layer on a substrate P+ layer; masking, patterning and etching to remove, in a first direction, a portion of the hard mask, the sacrificial material, the bottom electrode; depositing a layer of silicon oxide; masking, patterning and etching to remove, in a second direction perpendicular to the first direction, a portion of the hard mask, the sacrificial material, the bottom electrode;, and over etching to an N+ layer and at least 100 nm of the silicon substrate; depositing of a layer of silicon oxide; etching to remove any remaining hard mask and any remaining sacrificial material; depositing a layer of CMR material; depositing a top electrode; applying photoresist, patterning the photoresist and etching the top electrode; and incorporating the memory array into an integrated circuit.
