  • Publication number: 20240098969
    Abstract: Systems, methods and apparatus are provided for an array of vertically stacked memory cells having horizontally oriented access devices and storage nodes formed in tiers. And, more particularly, to multiple, alternating silicon germanium (SiGe) and single crystalline silicon (Si) in different thicknesses to form tiers in which to form the horizontal access devices in vertical three-dimensional (3D) memory. The horizontally oriented access devices can have a first source/drain regions and a second source drain regions separated by single crystalline silicon (Si) channel regions. The single crystalline silicon (Si) channel regions can include a dielectric material to provide support structure to the single crystalline channel regions when forming the horizontal access devices in vertical three-dimensional (3D) memory. Horizontally oriented access lines can connect to gate structures opposing the channel regions. Vertical digit lines coupled to the first source/drain regions.

  • Publication number: 20240098970
    Abstract: Systems, methods and apparatus are provided for an array of vertically stacked memory cells having horizontally oriented access devices and storage nodes. The horizontally oriented access devices having a first source/drain regions and a second source drain regions separated by silicon (Si) channel regions. A digit line having a global digit line (GDL) contact is formed in a trench adjacent to the first source/drain regions. In one example, the digit line is electrically isolated from a neighboring digit line at the bottom of the trench. In another example, the digit line is formed continuously along a bottom surface of trench to form shared digit lines between horizontal access devices, in two separate arrays, on opposing second vertical surfaces. The memory cells have horizontally oriented storage nodes coupled to the second source/drain regions and vertical digit lines coupled to the first source/drain regions.

  • Publication number: 20240074141
    Abstract: Methods and devices for a lateral three-dimensional memory device, are described herein. One method includes forming a thin film transistor including a first thermal process having a first range of temperatures, forming a capacitor bottom electrode of a capacitor structure including a second thermal process having a second range of temperature, wherein a maximum temperature in the second range of temperatures is less than a maximum temperature in the first range of temperatures, forming a CMOS structure including a third thermal process having a third range of temperatures, wherein a maximum temperature in the third range of temperatures is less than a maximum temperature in the second range of temperatures, and forming at least one other part of the capacitor structure.

  • Publication number: 20070294922
    Abstract: An adjustable orthotic insole and a unique method of implementation has a shell and a sole lifter that is to correct malalignment of lower extremities and other functions such as cushioning, massage, etc are not anticipated. The distribution of ground reaction force is changed due to the orthotic effect of the sole lifter. A user adjusts position and thickness of the sole lifter incessantly until malalignment of lower extremities is restored to optimal alignment symmetrically. The present invention employs a unique method that the sole lifter is always opposite to rear foot lifter. Once the malalignment of lower extremities is corrected by the orthotic insole, the user would be able to maintain good posture and ambulate in ideal gait. Therefore, symmetric and coordinated movements are harmonious with balanced muscle function. The musculoskeletal system would be protected from overuse injury.
