A memory device and a method for fabricating the same are provided. The memory device includes a substrate, a first active region, a second active region, a gate structure, and a capping layer. The first active region and the second active region are alternately disposed in the substrate. The gate structure is disposed in the substrate and between the first active region and the second active region. The capping layer is over the gate structure to define a void therebetween.

An electronic component of integrated circuitry comprises a substrate comprising at least two terminals. Material of one of the terminals has an upper surface. A conductive via extends elevationally into the material of the one terminal. The conductive via extends laterally into the material of the one terminal under the upper surface of the one terminal. Material of the one terminal is above at least some of the laterally extending conductive via. Other embodiments, including method embodiments, are disclosed.

Provided is a method for manufacturing a semiconductor device including a film to be treated having a high flatness. A semiconductor substrate having a surface and including a first region and a second region on the surface is prepared, the first region being a region in which a plurality of first level difference portions are formed, the second region being a region in which a plurality of second level difference portions arranged more sparsely than the plurality of first level difference portions are formed, or a region in which no level difference portion is formed. A photosensitive film is formed on a portion of the second region to surround a periphery of the first region as seen in plan view. An applied film having flowability is formed to cover the first region and the photosensitive film. A portion of the applied film at least on the first region is removed.

A memory structure, includes (a) active columns of polysilicon formed above a semiconductor substrate, each active column extending vertically from the substrate and including a first heavily doped region, a second heavily doped region, and one or more lightly doped regions each adjacent both the first and second heavily doped region, wherein the active columns are arranged in a two-dimensional array extending in second and third directions parallel to the planar surface of the semiconductor substrate; (b) charge-trapping material provided over one or more surfaces of each active column; and (c) conductors each extending lengthwise along the third direction. The active columns, the charge-trapping material and the conductors together form a plurality of thin film transistors, with each thin film transistor formed by one of the conductors, a portion of the lightly doped region of an active column, the charge-trapping material between the portion of the lightly doped region and the conductor, and the first and second heavily doped regions. The thin film transistors associated with each active column are organized into one or more vertical NOR strings.

Embodiments of the present disclosure generally relate to data storage and computer memory systems, and more particularly, to a SOT-MRAM chip architecture. The SOT-MRAM chip architecture includes a plurality of leads, a plurality of memory cells, and a plurality of transistors. The leads may be made of a material having large spin-orbit coupling strength and high electrical resistivity. Each lead of the plurality of leads may include a plurality of first portions and a plurality of second portions distinct from the first portions. The electrical resistivity of the second portions is less than that of the first portions, so the total electrical resistivity of the lead is reduced, leading to improved power efficiency and signal to noise ratio.

Some embodiments include an integrated structure having stacked conductive levels. At least some of the conductive levels are wordline levels and include control gate regions of memory cells. One of the conductive levels is a vertically outermost conductive level along an edge of the stack. Vertically-extending channel material is along the conductive levels. Some of the channel material extends along the memory cells. An extension region of the channel material is vertically outward of the vertically outermost conductive level. A charge-storage structure has a first region directly between the vertically outermost conductive level and the channel material, and has a second region which extends vertically outward of the vertically outermost conductive level and is along the extension region of the channel material.

Methods of forming 3-D ICs with integrated passive devices (IPDs) include stacking separately prefabricated substrates. An active device (AD) substrate has contacts on its upper portion. A ground plane is located between the AD substrate and an IPD substrate. The ground plane provides superior IPD to AD cross-talk attenuation.

A method for selectively etching a tungsten layer on a substrate includes arranging a substrate including a tungsten layer on a substrate support. The substrate processing chamber includes an upper chamber region, an inductive coil arranged outside of the upper chamber region, a lower chamber region including the substrate support and a gas dispersion device arranged between the upper and lower chamber regions. The gas dispersion device includes a plurality of holes in fluid communication with the upper and lower chamber regions. The method further includes controlling pressure in the substrate processing chamber in a range from 0.4 Torr to 10 Torr; supplying an etch gas mixture including fluorine-based gas to the upper chamber region; striking inductively coupled plasma in the upper chamber region by supplying power to the inductive coil; and selectively etching the tungsten layer relative to at least one other film material of the substrate.
