Latest Patents

One of Takashi Arai's key patents is titled "Selective tungsten growth for word lines of a three-dimensional memory device." This patent focuses on preventing void formation in tungsten lines within a three-dimensional memory device. By incorporating polycrystalline aluminum oxide liners in specific areas, Arai's method allows tungsten to nucleate on these liners before it does on a metallic liner layer. This technique enables the deposition of tungsten layers from the center of each backside recess, facilitating growth towards the backside trenches. The result is a void-free tungsten layer that enhances the structural integrity of the memory device. Arai holds 1 patent in this area.
