Resistive Switching for MEMS Devices
A MEMS device includes a bolometer attached to a silicon wafer by a base portion of at least one anchor structure. The base portion comprises a layer stack having a metal-insulator-metal (MIM) configuration such that the base portion acts as a resistive switch such that, when the first DC voltage is applied to the patterned conductive layer, the base portion transitions from a high resistive state to a low resistive state, and, when the second DC voltage is applied to the patterned conductive layer, the base portion transitions from a high resistive state to a low resistive state.
High density memory devices with low cell leakage and methods for forming the same
A memory device including a first array of rail structures that extend along a first horizontal direction, in which each of the rail structures are formed to serve as a bottom electrode, and a second array of rail structures that laterally extend along a second horizontal direction and are laterally spaced apart along the first horizontal direction. Each of the rail structures in the second array are formed to server as a top electrode. The memory device also includes a continuous dielectric memory layer located between the first array of rail structures and the second array of rail structures. The continuous dielectric memory layer providing protection from current leakage between the rail structures of the first array and the rail structures of the second array.
Apparatus and Methods for Electrical Switching
Electrical switching technologies employ the otherwise undesirable line defect in crystalline materials to form conductive filaments. A switching cell includes a crystalline layer disposed between an active electrode and another electrode. The crystalline layer has at least one channel, such as a line defect, extending from one surface of the crystalline layer to the other surface. Upon application of a voltage on the two electrodes, the active electrode provides metal ions that can migrate from the active electrode to the other electrode along the line defect, thereby forming a conductive filament. The switching cell can precisely locate the conductive filament within the line defect and increase the device-to-device switching uniformity.

Nanoporous metal-oxide memory
A nanoporous (NP) memory may include a non-porous layer and a nanoporous layer sandwiched between the bottom and top electrodes. The memory may be free of diodes, selectors, and/or transistors that may be necessary in other memories to mitigate crosstalk. The nanoporous material of the nanoporous layer may be a metal oxide, metal chalcogenide, or a combination thereof. Further, the memory may lack any additional components. Further, the memory may be free from requiring an electroformation process to allow switching between ON/OFF states.

IN-SITU LOW TEMPERATURE DIELECTRIC DEPOSITION AND SELECTIVE TRIM OF PHASE CHANGE MATERIALS
A method of fabricating a resistive semiconductor memory structure that provides in-situ selective etch of phase change materials during deposition of dielectric at low temperature (in the same chamber). The method provides, to a single processing chamber, a semiconductor wafer including a trimmed resistive memory device structure having one or more layers of phase change material used to form a resistive memory device. The one or more layers of phase change material have oxidized sidewall surfaces as a result of a prior etching step where a whole stack structure of the layers forming the resistive memory structure is etched. Then, an encapsulating of the trimmed resistive memory device structure is performed by depositing, within the processing chamber, using a PECVD, a layer of dielectric material, and during the encapsulating, etching, within the processing chamber, the wafer to selectively remove the phase change material oxidation at the sidewall surfaces.
