Abstract:
An alternating stack of insulating layers and sacrificial material layers can be formed over a substrate. Memory stack structures and a backside trench are formed through the alternating stack. Backside recesses are formed by removing the sacrificial material layers from the backside trench selective to the insulating layers. A cobalt-containing material is deposited such that the cobalt-containing material continuously extends at least between a neighboring pair of cobalt-containing material portions in respective backside recesses. An anneal is performed at an elevated temperature to migrate vertically-extending portions of the cobalt-containing material into the backside recesses, thereby forming vertically separated cobalt-containing material portions confined within the backside recesses. Sidewalls of the insulating layers may be rounded or tapered to facilitate migration of the cobalt-containing material.
Abstract:
An integrated circuit structure (100) includes: a semiconductor substrate (102); a shallow trench isolation (STI) region (106) in the semiconductor substrate (102); one or more active devices formed on the semiconductor substrate (102); and a resistor array (138) having a plurality of resistors disposed above the STI region (106); wherein the resistor array (138) comprises a portion of one or more interconnect contact layers (126, 136) that are for interconnection to the one or more active devices.
Abstract:
The present description relates to a gallium nitride transistor which includes at least one source/drain structure having low contact resistance between a 2D electron gas of the gallium nitride transistor and the source/drain structure. The low contact resistance may be a result of at least a portion of the source/drain structure being a single-crystal structure abutting the 2D electron gas. In one embodiment, the single-crystal structure is grown with a portion of a charge inducing layer of the gallium nitride transistor acting as a nucleation site.
Abstract:
Light-emitting devices having a multiple quantum well (MQW) pin diode structure and methods of making and using the devices are provided. The devices are composed of multilayered semiconductor heterostructures. The devices include one or more interfacial layers of a material that allows current tunneling through lattice mismatched heterogeneous junctions at the interfaces between the intrinsic active region and the p-type and/or n-type doped charge injection layers.
Abstract:
A monolithic three dimensional NAND string includes a plurality of control gate electrodes extending substantially parallel to a major surface of a substrate in at least one active region, a plurality of semiconductor channels having at least one end portion of each of the plurality of semiconductor channels extending substantially perpendicular to the major surface of the substrate, at least one memory film located between each of the plurality of control gate electrodes and each respective semiconductor channel of the plurality of semiconductor channels, and at least one first slit trench extending substantially perpendicular to the major surface of the substrate. Each of the plurality of control gate electrodes has a nonlinear side wall adjacent to the at least one first slit trench in the at least one active region.
Abstract:
A metal insulator semiconductor field effect transistor (MISFET) such as a super junction metal oxide semiconductor FET with high voltage breakdown is realized by, in essence, stacking a relatively low aspect ratio column (trenches filled with dopant, e.g., p-type dopant) on top of a volume or volumes formed by implanting the dopant in lower layers. Together, the low aspect ratio column and the volume(s) form a continuous high aspect ratio column.
