    Abstract: Technical solutions are described for fabricating a semiconductor wafer. An example method includes generating a process assumption band for an element of the wafer. The process assumption band depicts a shape of the element based on a set of process variations in a photolithographic process used for fabricating the wafer. The method also includes generating a process variation band for the element of the wafer based on optical process correction simulation of the photolithographic process using design rules associated with the wafer. The method also includes determining a deviation between the process assumption band and the process variation band, and recalculating one or more design rules from the design rules associated with the wafer based on the deviation. The method also includes updating the design of the wafer in response to the process variation band not being changeable to match the process assumption band, after recalculating the design rules.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.
