Abstract: An alternating stack of sacrificial material layers and insulating layers is formed over a substrate. Replacement of sacrificial material layers with electrically conductive layers can be performed employing a subset of openings. A predominant subset of the openings is employed to form memory stack structures therein. A minor subset of the openings is employed as access openings for introducing an etchant to remove the sacrificial material layers to form lateral recesses and to provide a reactant for depositing electrically conductive layers in the lateral recesses. By distributing the access openings across the entirety of the openings and eliminating the need to employ backside trenches for replacement of the sacrificial material layers, the size and lateral extent of backside trenches can be reduced to a level sufficient to accommodate only backside contact via structures.

Abstract: Split memory cells can be provided within an alternating stack of insulating layers and word lines. At least one lower-select-gate-level electrically conductive layers and/or at least one upper-select-level electrically conductive layers without a split memory cell configuration can be provided by limiting the levels of separator insulator structures within the levels of the word lines. At least one etch stop layer can be formed above at least one lower-select-gate-level spacer material layer. An alternating stack of insulating layers and spacer material layers is formed over the at least one etch stop layer. Separator insulator structures are formed through the alternating stack employing the etch stop layer as a stopping structure. Upper-select-level spacer material layers can be subsequently formed. The spacer material layers and the select level material layers are formed as, or replaced with, electrically conductive layers.

Abstract: A switching field effect transistor and the memory devices can be formed employing a same set of processing steps. An alternating stack of insulating layers and sacrificial material layers is formed over a substrate. Memory stack structures for memory devices and gate dielectric-channel structures for the field effect transistor can be simultaneously formed in a memory region and in a transistor region, respectively. After replacement of the sacrificial material layers with electrically conductive layers, portions of the electrically conductive layers in a memory region are electrically isolated from one another to provide independently controlled control gate electrodes for the memory devices, while portions of the electrically conductive layers in the transistor region are electrically shorted among one another to provide a single gate electrode for the switching field effect transistor.

Abstract: A bookbinding apparatus includes an application roller that applies glue onto a back edge face of a sheet bundle and a bookbinding control unit that positions the application roller onto the back edge face and causes the roller to execute glue application. The bookbinding apparatus applies a required amount of glue determined by a sheet bundle thickness by, after applying side glues to both side surfaces of the sheet bundle, bringing the application roller in contact with a first position within a central region on the back edge face and rotating the roller in a forward direction, bringing the application roller in contact with a second position between the first position and a right side of the sheet bundle, and rotating the roller in the forward direction. The glue is leveled to form a flat layer of adhesive with an adequate thickness.

Abstract: An alternating stack of insulating layers and sacrificial material layers are formed over a substrate. Memory stack structures are formed through the alternating stack. A backside trench is formed and the sacrificial material layers are replaced with electrically conductive layers. After formation of an insulating spacer in the trench, an epitaxial pedestal structure is grown from a semiconductor portion underlying the backside trench. A source region is formed by introducing dopants into the epitaxial pedestal structure and an underlying semiconductor portion during and/or after epitaxial growth. Alternatively, the backside trench can be formed concurrently with formation of memory openings. An epitaxial pedestal structure can be formed concurrently with formation of epitaxial channel portions at the bottom of each memory opening.

Abstract: A field effect transistor having a higher breakdown voltage can be provided by forming a contiguous dielectric material layer over gate stacks, forming via cavities laterally spaced from the gate stacks, selectively depositing a single crystalline semiconductor material, and converting upper portions of the deposited single crystalline semiconductor material into elevated source/drain regions. Lower portions of the selectively deposited single crystalline semiconductor material in the via cavities can have a doping of a lesser concentration, thereby effectively increasing the distance between two steep junctions at edges of a source region and a drain region. Optionally, embedded active regions for additional devices can be formed prior to formation of the contiguous dielectric material layer. Raised active regions contacting a top surface of a substrate can be formed simultaneously with formation of the elevated active regions that are vertically spaced from the top surface.
