  • Patent number: 10290803
    Abstract: A wedge-shaped contact region can be employed to provide electrical contacts to multiple electrically conductive layers in a three-dimensional device structure. A cavity including a generally wedge-shaped region and a primary region is formed in a dielectric matrix layer over a support structure. An alternating stack of insulating layers and electrically conductive layers is formed by a series of conformal deposition processes in the cavity and over the dielectric matrix layer. The alternating stack can be planarized employing the top surface of the dielectric matrix layer as a stopping layer. A tip portion of each electrically conductive layer within remaining portions of the alternating stack is laterally offset from the tip of the generally wedge-shaped region by a respective lateral offset distance along a lateral protrusion direction. Contact via structures can be formed on the tip portions of the electrically conductive layers to provide electrical contact.

  • Patent number: 9666799
    Abstract: An alternating stack of electrically conductive layers and electrically insulating layers is formed over global bit lines formed on a substrate. The alternating stack is patterned to form a line stack of electrically conductive lines and electrically insulating lines. Trench isolation structures are formed within each trench to define a plurality of memory openings laterally spaced from one another by the line stack in one direction and by trench isolation structures in another direction. The electrically conductive lines are laterally recessed relative to sidewall surfaces of the electrically insulating lines. A read/write memory material is deposited in recesses, and is anisotropically etched so that a top surface of a global bit line is physically exposed at a bottom of each memory opening. An electrically conductive bit line is formed within each memory opening to form a resistive random access memory device.
