Abstract: Approaches for providing a narrow diffusion break in a fin field effect transistor (FinFET) device are disclosed. Specifically, the FinFET device is provided with a set of fins formed from a substrate, and an opening formed through the set of fins, the opening oriented substantially perpendicular to an orientation of the set of fins. This provides a FinFET device capable of achieving cross-the-fins insulation with an opening size that is adjustable from approximately 20-30 nm.

Abstract: Interconnect structures and methods for forming an interconnect structure. First and second metallization structures are formed in an intralayer dielectric layer. The intralayer dielectric layer is removed to form a cavity with an entrance between the first and second metallization structures. A dielectric layer is deposited on surfaces surrounding the cavity, over the first metallization structure, and over the second metallization structure. A sacrificial material is formed inside the cavity after the dielectric layer is deposited. A cap layer is deposited on the dielectric layer over the first metallization structure, the dielectric layer over the second metallization structure, and the sacrificial material inside the cavity to close the entrance to the cavity. After the cap layer is deposited, the sacrificial material is removed from the cavity. The dielectric layer and cap layer cooperate to encapsulate an air gap inside the cavity.

Abstract: The disclosure is directed to methods of identifying a space within an integrated circuit structure as a mandrel space or a non-mandrel space. One method may include: identifying a space between freestanding spacers as being one of: a former mandrel space created by removal of a mandrel from between the freestanding spacers or a non-mandrel space between adjacent mandrels prior to removal of the mandrel, based on a line width roughness of the space, wherein the line width roughness represents a deviation of a width of the space from a centerline axis along a length of the space.
