Latest Patents

Doda's latest patents include a multi-tier three-dimensional memory device with dielectric support pillars and methods for making the same. This innovative memory array consists of 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 stacks are formed by alternating 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, offering flexibility in design.
