Abstract: Some embodiments include an assembly having conductive structures distributed along a level within a memory array region and another region proximate the memory array region. The conductive structures include a first stack over a metal-containing region. A semiconductor material is within the first stack. A second stack is over the conductive structures, and includes alternating conductive tiers and insulative tiers. Cell-material-pillars are within the memory array region. The cell-material-pillars include channel material. The semiconductor material directly contacts the channel material. Conductive post structures are within the other region. Some of the conductive post structures are dummy structures and have bottom surfaces which are entirely along an insulative oxide material. Others of the conductive post structures are live posts electrically coupled with CMOS circuitry. Some embodiments include methods of forming assemblies.

Abstract: A microelectronic device comprises a stack structure, at least one staircase structure, contact structures, and support structures. The stack structure comprises vertically alternating conductive structures and insulating structures arranged in tiers, each of the tiers individually comprising one of the conductive structures and one of the insulating structures. The at least one staircase structure is within the stack structure and has steps comprising edges of at least some of the tiers. The contact structures are on the steps of the at least one staircase structure. The support structures horizontally alternate with the contact structures in a first horizontal direction and vertically extend through the stack structure. The support structures have oblong horizontal cross-sectional shapes. Additional microelectronic devices, memory devices, and electronic systems are also described.

Abstract: A microelectronic device comprises a stack structure comprising an alternating sequence of conductive material and insulative material arranged in tiers, and having blocks separated by dielectric slot structures. Each of the blocks comprises a stadium structure, a filled trench overlying the stadium structure, support structures extending through the filled trench and tiers of the stack structure, and dielectric liner structures covering sidewalls of the support structures. The stadium structure comprises staircase structures each having steps comprising edges of the tiers of the stack structure. The filled trench comprises a dielectric material interposed between at least two additional dielectric materials. The dielectric liner structures comprise first protrusions at vertical positions of the dielectric material, and second protrusions at vertical positions of the conductive material of the tiers of the stack structure. The second protrusions have greater horizontal dimensions than the first protrusions.

Abstract: A vehicle seat and an angle adjustment device are provided. The angle adjustment device includes an unlock cam, a ratchet wheel provided with internal teeth, and a plurality of slide blocks disposed circumferentially and provided with external teeth. The angle adjustment device further includes a plurality of extension and retraction blocks corresponding to the slide blocks, wherein the extension and retraction block is capable of driving the slide block to move outwards in a radial direction so as to engage the internal teeth with the external teeth. A second elastic member is provided between two adjacent extension and retraction blocks, and two ends of the second elastic member in a deformation direction are respectively connected to the unlock cam and the extension and retraction block.

Abstract: An angle adjusting device is provided, which includes a ratchet, multiple sliders, an expansion and retraction mechanism, and a sliding groove plate. The ratchet is provided with n inner teeth; and m slider groups consisting of the multiple sliders include one base slider group and m?1 deflecting slider groups, where the outer teeth of the deflecting slider groups have an angular deflection about a central shaft of the ratchet with respect to the outer teeth of the base slider group, and the angular deflection is (Z+k/m)360/n degrees, and 1?k?m?1, and the expansion and retraction mechanism is capable of simultaneously push the multiple sliders to extend in radial directions. The outer teeth of different sliders can simultaneously abut against or be engaged with the inner teeth at different phases, thus achieving the stable securing and stepless adjusting of the ratchet position.
