  • Publication number: 20240099014
    Abstract: At least one vertically alternating sequence of continuous insulating layers and continuous sacrificial material layers is formed over a substrate. Rows of backside support pillar structures are formed through the at least one vertically alternating sequence. Memory stack structures are formed through the at least one vertically alternating sequence. A two-dimensional array of discrete backside trenches is formed through the at least one vertically alternating sequence. Contiguous combinations of a subset of the backside trenches and a subset of the backside support pillar structures divide the at least one vertically alternating sequence into alternating stacks of insulating layers and sacrificial material layers. The sacrificial material layers are replaced with electrically conductive layers while the backside support pillar structures provide structural support to the insulating layers.

  • Patent number: 7830590
    Abstract: In a magnetic display panel that changes the display using a magnet, a polychrome display panel is obtained that magnetically displays two colors in addition to the background, thus, specifically, magnetically displays three colors. The magnetic migration and reversal display panel encloses a dispersion liquid obtained by dispersing micro-magnets with differently colored magnetic poles in a dispersion medium containing a colorant. After writing representing two display colors is obtained by selecting a specified magnetic pole, causing from the front surface side the migration or migration/reversal of the micro-magnets in the dispersion liquid, and displaying the color tone of the specified surface of the micro-magnets, the color tone of writing is changed without changing the state of writing by causing the magnetic field of the opposite magnetic pole to act from the same surface side on the micro-magnets configuring the writing where the color tone is displayed.
