Latest Patents

One of Fu's latest patents is titled "Cross-point magnetoresistive random memory array and method of making thereof using self-aligned patterning." This invention describes a memory device that includes a cross-point array of magnetoresistive memory cells. Each cell features a vertical stack of a selector-containing pillar structure and a magnetic tunnel junction pillar structure. The design allows for smaller lateral spacing between neighboring pairs of memory cells in one direction compared to another. Techniques such as using a dielectric spacer or a tapered etch process are employed to create an etch mask pattern for the electrically conductive lines beneath the memory cells. Additionally, a protective dielectric liner can be used to safeguard the selector-containing pillar structures during the formation of the magnetic tunnel junction pillar structures.

Another notable patent is the "Resistive memory device including a lateral air gap around a memory element and method of making thereof." This invention involves forming electrically conductive lines over a substrate and creating a two-dimensional array of vertical stacks. Each stack consists of a first electrode, an in-process resistive memory material portion, and a second electrode. The design features laterally recessed sidewalls of the resistive memory material portions, which are surrounded by a dielectric material layer that forms annular cavities. This innovative approach enhances the performance of resistive memory devices.
