  • Patent number: 10269817
    Abstract: A three-dimensional memory array device can include mid-plane terrace regions between a pair of memory array regions. The electrically conductive layers of the three-dimensional memory array device continuously extend between the pair of memory array regions through a connection region, which is provided adjacent to the mid-plane terrace regions. Contact via structures contacting the electrically conductive layers can be provided in the mid-plane terrace regions, and through-memory-level via structures that extend through the alternating stack and connected to underlying lower metal interconnect structures and semiconductor devices can be provided through the mid-plane terrace region and/or through the connection region. Upper metal interconnect structures can connect the contact via structures and the through-memory-level via structures.

  • Patent number: 10256248
    Abstract: Lower level metal interconnect structures are formed over a substrate with semiconductor devices thereupon. A semiconductor material layer and an alternating stack of spacer dielectric layers and insulating layers is formed over the lower level metal interconnect structures. An array of memory stack structures is formed through the alternating stack. Trenches are formed through the alternating stack such that a staircase region is located farther away from a threshold lateral distance from the trenches, while neighboring staircase regions are formed within the threshold lateral distance from the trenches. Portions of the spacer dielectric layers proximal to the trenches are replaced with electrically conductive layers, while a remaining portion of the alternating stack is present in the staircase region.

    Abstract: A power transmission apparatus for a vehicle includes an engagement mechanism and a switching mechanism. The switching mechanism includes: a hydraulic cylinder; a regulation valve regulates a hydraulic pressure to be supplied to a first oil chamber and a second oil chamber; a rocking valve switches a state of a hydraulic circuit between a closed circuit state and an open circuit state; and an oil pump supplies the hydraulic pressure to the hydraulic cylinder. The switching mechanism switches the engagement mechanism between an engaged state and a disengaged state after the hydraulic circuit is switched from the closed circuit state to the open circuit state by the rocking valve. The switching mechanism keeps the engaged state or the disengaged state of the engagement mechanism after switching the engaged state or the disengaged state of the engagement mechanism.

  • Publication number: 20190057741
    Abstract: The total chip area for a three-dimensional memory device can be reduced employing a design layout in which the word line decoder circuitry is formed underneath an array of memory stack structures. The interconnection between the word lines and the word line decoder circuitry can be provided by forming discrete word line contact via structures. The discrete word line contact via structures can be formed by employing multiple sets of etch masks with overlapping opening areas and employed to etch a different number of pairs of insulating layers and electrically conductive layers, thereby obviating the need to form staircase regions having stepped surfaces. Sets of at least one conductive interconnection structure can be employed to provide vertical electrical connection to the word line decoder circuitry. Bit line drivers can also be formed underneath the array of memory stack structures to provide greater areal efficiency.

  • Patent number: 10192877
    Abstract: A mesa structure is formed over a substrate. An alternating stack of insulating layers and spacer material layers having a total height of approximately double the height of the mesa structure is formed over the substrate and the mesa structure. The spacer material layers are formed as, or are replaced with, electrically conductive layers. Portions of the alternating stack are removed from above the mesa structure by a planarization process. Stepped surfaces can be concurrently formed in a first terrace region overlying the mesa structure and in a second terrace region located at an opposite side of a memory array region of the alternating stack. A pair of level shifted stepped surfaces is formed. Contacts to the alternating stack can reach down only to the lowest surface of the pair of level shifted stepped surfaces, and can be shorter than the alternating stack.

  • Patent number: 10175836
    Abstract: A touch panel is realized that is able to decrease the amount of dead space at the periphery of the touch panel and that has highly accurate touch panel sensitivity. In a touch panel, Y direction conductive patterns are arranged so as to be separated from wiring patterns in Y direction conductive pattern regions between electrode units of X direction conductive patterns. As a result, in this conductive sheet, it is possible to appropriately prevent the occurrence of parasitic capacitance resulting from the Y direction conductive patterns and the wiring patterns. Therefore, in a touch panel device or the like that uses such a touch panel, it is possible to effectively prevent the generation of noise that overlaps sense signals as a result of the above-mentioned parasitic capacitance, thereby making it possible to realize highly accurate touch panel sensitivity.

  • Patent number: 10115632
    Abstract: An alternating stack of insulating layers and sacrificial material layers is formed over a horizontal layer, which can be formed over a lower-interconnect-level dielectric material layer overlying a substrate. Structural integrity of insulating layers vertically spaced from one another by backside recesses during replacement of sacrificial material layers with electrically conductive layers can be enhanced by forming electrically inactive laterally-insulated support structures concurrently with formation of laterally-insulated conductive via structures that vertically extend through each layer in the alternating stack and through the horizontal layer and to lower-interconnect-level metal interconnect structures. Alternatively or additionally, the structural integrity of insulating layers during the replacement process can be enhanced by M×N array of semiconductor-containing support structures that extend through staircase region and having same materials as memory stack structures.

  • Publication number: 20180277566
    Abstract: An annular dielectric spacer can be formed at a level of a joint-level dielectric material layer between vertically neighboring pairs of alternating stacks of insulating layers and spacer material layers. After formation of a memory opening through multiple alternating stacks and formation of a memory film therein, an anisotropic etch can be performed to remove a horizontal bottom portion of the memory film. The annular dielectric spacer can protect underlying portions of the memory film during the anisotropic etch. In addition, a silicon nitride barrier may be employed to suppress hydrogen diffusion at an edge region of peripheral devices.
