Abstract: Structures for an electronic fuse and methods of forming an electronic fuse. The structure includes a first terminal, a second terminal, and a fuse link extending from the first terminal to the second terminal. The structure further includes a silicide layer having a first portion included in the fuse link and a second portion included in the first terminal and the second terminal. The first portion of the silicide layer has a first thickness, the second portion of the silicide layer has a second thickness, and the first thickness is less than the second thickness.

Abstract: One illustrative method disclosed herein includes, among other things, performing at least one etching process to expose at least a portion of an upper surface of a gate electrode of a first transistor device and at least a vertical portion of one side surface of the gate electrode and performing a material growth process to form a conductive gate-to-source/drain (GSD) contact structure that conductively couples the gate electrode of the first transistor device to a source/drain region of the first transistor device, wherein the conductive GSD contact structure comprises a non-single crystal material portion positioned on previously exposed portions of the gate electrode and a single crystal material portion positioned in the source/drain region.

Abstract: A method of forming nanosheet and nanowire transistors includes the formation of alternating epitaxial layers of silicon germanium (SiGe) and silicon (Si). The silicon germanium layers include etch-selective high-germanium content silicon germanium layers and low-germanium content silicon germanium layers. Single work function metal PFET and NFET devices can be formed on the same substrate by incorporating the low-germanium content silicon germanium layers into the channel region within p-type device regions, whereas both the high-germanium content silicon germanium layers and the low-germanium content silicon germanium layers are removed from within n-type device regions.

Abstract: When patterning active regions for sophisticated semiconductor devices, the cutting through active semiconductor regions previously patterned along a first lateral direction so as to obtain elongated semiconductor lines may be performed in a late manufacturing stage. That is, the cutting may be performed after patterning at least a portion of the gate electrode structures, thereby achieving a self-aligned patterning regime and also contributing to a reduction of strain loss.

Abstract: Device structures for a FinFET and fabrication methods for making a device structure for a FinFET. A first layer containing a first dopant is formed on a first region of a substrate. A second layer containing a second dopant is formed on a second region of the substrate. A first plurality of fins are formed and are each located in a respective trench extending from the substrate through the first layer. A second plurality of fins are formed and are each located in a respective trench extending from the substrate through the second layer. The first dopant is transferred from the first layer to a first section in each of the first plurality of fins and the second dopant is transferred from the second layer to a first section in each of the second plurality of fins.

Abstract: Gate height scaling in sophisticated semiconductor devices may be implemented without requiring a redesign of non-transistor devices. To this end, the semiconductor electrode material may be adapted in its thickness above active regions and isolation regions that receive the non-transistor devices. Thereafter, the actual patterning of the adapted gate layer stack may be performed so as to obtain gate electrode structures of a desired height for improving, in particular, AC performance without requiring a redesign of the non-transistor devices.
