Latest Patents
One of Kei Nozawa's latest patents is titled "Multi-tier three-dimensional memory device with dielectric support pillars and methods for making the same." This invention describes a multi-tier three-dimensional memory array that includes multiple alternating stacks of insulating layers and electrically conductive layers that are vertically stacked. The memory stack structures, which include memory films and semiconductor channels, extend through these alternating stacks. The alternating stacks are initially formed with insulating layers and sacrificial material layers, which are later modified by replacing the sacrificial layers with electrically conductive layers. Structural support during this replacement process is provided by the memory stack structures and dielectric support pillar structures. These dielectric support pillars can be formed for a first-tier structure or may extend over multiple tiers, enhancing the overall stability and functionality of the memory device.
