  • Publication number: 20240138145
    Abstract: A method used in forming a memory array comprising strings of memory cells comprises forming a stack comprising vertically-alternating first tiers and second tiers. A channel-material string is in individual channel openings in the vertically-alternating first tiers and second tiers. A conductor-material contact is in the individual channel openings directly against the channel material of individual of the channel-material strings. The conductor-material contacts are vertically recessed in the individual channel openings. A conductive via is formed in the individual channel openings directly against the vertically-recessed conductor-material contact in that individual channel opening. Other aspects, including structure independent of method, are disclosed.

  • Publication number: 20240112734
    Abstract: A variety of applications can include memory devices designed to provide enhanced gate-induced-drain-leakage (GIDL) current during memory erase operations. The enhanced operation can be provided by enhancing the electric field in the channel structures of select gate transistors to strings of memory cells. The channel structures can be implemented as a segmented portion for drains and a portion opposite a gate. The segmented portion includes one or more fins and one or more non-conductive regions with both fins and non-conductive regions extending vertically from the portion opposite the gate. Variations of a border region for the portion opposite the gate with the segmented portion can include fanged regions extending from the fins into the portion opposite the gate or rounded border regions below the non-conductive regions. Such select gate transistors can be formed using a single photo mask process. Additional devices, systems, and methods are discussed.

  • Patent number: 11841605
    Abstract: A trail camera mounting and camouflaging device having a trail camera mounting point and a mounting bracket for mounting the camouflaging device to a substrate, such as a tree or other material. The camouflaging device has a series of flexible arms that extend outward away from the mounting bracket. The flexible arms are configured to be bent and otherwise manipulated into retaining the shape of the bend or manipulation. Each flexible arms has one or more fingers attached to the flexible arm. The fingers can utilize a flexible material such as a twist tie or can otherwise be configured with a clipping or clamping motion to attach foliage to the fingers. The flexible arms and fingers are configured to be manipulated and bent into position, such that foliage or other material camouflages the trails camera without blocking the sensor(s) of the trail camera.

  • Publication number: 20230397419
    Abstract: For manufacturing a memory device, a system may form a trench between a first portion and a second portion of a stack. A bottom wall of the trench may include a spacer material. The system may remove a first and a second oxide material to reform the trench, and remove a polysilicon material in a lateral direction to expose a third oxide material and a channel structure. The third oxide material may form the bottom wall of the trench. The system may remove, in a lateral direction, the first oxide material, a portion of the second oxide material, the third oxide material, and a fourth oxide material of the channel structure. The system may deposit a metal material, in the trench, in contact with a doped polysilicon material of the channel structure.

  • Patent number: 11756826
    Abstract: A termination opening can be formed through the stack alternating dielectrics concurrently with forming contact openings through the stack. A termination structure can be formed in the termination opening. An additional opening can be formed through the termination structure and through the stack between groups of semiconductor structures that pass through the stack. In another example, an opening can be formed through the stack so that a first segment of the opening is between groups of semiconductor structures in a first region of the stack and a second segment of the opening is in a second region of the stack that does not include the groups of semiconductor structures. A material can be formed in the second segment so that the first segment terminates at the material. In some instances, the material can be implanted in the dielectrics in the second region through the second segment.
