  • Patent number: 9324731
    Abstract: A method for fabricating a memory device is provided: A multi-layer stack is formed on a substrate. The multi-layer stack is then patterned to form plural trenches extending along a first direction to define plural ridge-shaped stacks each of which comprises at least one conductive strip. Next, a memory layer and a channel layer are formed in sequence on bottoms and sidewalls of the trenches. A sacrifice layer is formed to fulfill the trenches. Subsequently, portions of the sacrifice layer, the memory layer and the channel layer formed in the trenches are removed to form plural openings exposing a portion of the substrate therefrom. After removing the remaining sacrifice layer, portions of the memory layer and the channel layer formed on the ridge-shaped stacks are patterned to form an interconnection between two adjacent trenches through two of the openings formed in the two adjacent trenches.

  • Patent number: 9245925
    Abstract: Metal oxide based memory devices and methods for manufacturing are described herein. A method for manufacturing a memory cell includes forming an insulation layer on an access device followed by forming vias through the insulation layer to expose the first and second access device terminals. First and second interlayer conductors extending through the vias are formed next. Top surfaces of the interlayer conductors are oxidized to form oxide layers. The oxide layer on the first interlayer conductor forms a memory layer. On top of the insulation layer a layer of protection metal is formed covering the oxide layers. The layer of protection metal is patterned and etched to form a top electrode layer covering the memory layer. The oxide layer on the second interlayer conductor is removed. Parallel first and second access lines are then formed on the top electrode layer and the second interlayer conductor, respectively.
