摘要: Methods of forming a settable resistance device, settable resistance devices, and neuromorphic computing devices include isotropically etching a stack of layers, the stack of layers having an insulator layer in contact with a conductor layer, to selectively form divots in exposed sidewalls of the conductor layer. The stack of layers is isotropically etched to selectively form divots in exposed sidewalls of the insulator layer, thereby forming a tip at an interface between the insulator layer and the conductor layer. A dielectric layer is formed over the stack of layers to cover the tip. An electrode is formed over the dielectric layer, such that the dielectric layer is between the electrode and the tip.

摘要: A method of forming a semiconductor structure includes forming a dielectric layer, forming a plurality of mandrel lines over the dielectric layer, and forming a plurality of non-mandrel lines over the dielectric layer between adjacent ones of the mandrel lines utilizing self-aligned double patterning. The method also includes forming at least one spacer-merge region extending from a first portion of a first one of the mandrel lines to a second portion of a second one of the mandrel lines in a first direction and covering at least a portion of one or more of the non-mandrel lines between the first mandrel and the second mandrel in a second direction orthogonal to the first direction. The method further includes forming a plurality of trenches in the dielectric layer by transferring a pattern of (i) the mandrel lines and (ii) portions of the non-mandrel lines outside the at least one spacer-merge region.

摘要: A method is presented for forming a nanowire electrode. The method includes forming a plurality of nanowires over a first substrate, depositing a conducting layer over the plurality of nanowires, forming solder bumps and electrical interconnections over a second flexible substrate, and integrating nanowire electrode arrays to the second flexible substrate. The plurality of nanowires are silicon (Si) nanowires, the Si nanowires used as probes to penetrate skin of a subject to achieve electrical biopotential signals. The plurality of nanowires are formed over the first substrate by metal-assisted chemical etching.

摘要: Methods and systems for performing an electronic design. A layout of a via of an electronic design is obtained and a determination is made if the layout of the via satisfies one or more retargeting conditions, at least one of the retargeting conditions being that a first edge of a metal line is within a specified distance from a first edge of the via and a second edge of the metal line is within the specified distance from a second edge of the via, the first edge of the metal line being parallel to the first edge of the via and the second edge of the metal line being parallel to the second edge of the via; and reducing a resistance of the via by the layout of the via is retargeted in response to the retargeting conditions being satisfied.

摘要: A method of performing co-integrated fabrication of a non-volatile memory (NVM) and a gate-all-around (GAA) nanosheet field effect transistor (FET) includes recessing fins in a channel region of the NVM and the FET to form source and drain regions adjacent to recessed fins, and removing alternating portions of the recessed fins of the NVM and the FET to form gaps in the recessed fins. A stack of layers that make up an NVM structure are conformally deposited within the gaps of the recessed fins leaving second gaps, smaller than the gaps, and above the recessed fins of the NVM while protecting the FET with the organic planarization layer (OPL) and a block mask. The OPL and block mask are removed from the FET, and another OPL and another block mask protect the NVM while a gate of the FET is formed above the recessed fins and within the gaps.

摘要: Embodiments are directed to a method of forming a semiconductor device and resulting structures that reduce shallow trench isolation (STI) undercutting, floating gates, and gate voids without degrading epitaxy quality. The method includes forming a first and second semiconductor fin on a substrate. A buffer layer is formed on a surface of the substrate between the first and second semiconductor fins and a semiconducting layer is formed on the buffer layer. The buffer layer is selectively removed and replaced with a dielectric layer. A first gate is formed over a first channel region of the first semiconductor fin and a second gate is formed over a second channel region of the first semiconductor fin. Source and drain epitaxy regions are selectively formed on surfaces of the first gate.
