Abstract: Self-aligned gate endcap (SAGE) architectures without fin end gaps, and methods of fabricating self-aligned gate endcap (SAGE) architectures without fin end gaps, are described. In an example, an integrated circuit structure includes a semiconductor fin having a cut along a length of the semiconductor fin. A gate endcap isolation structure has a first portion parallel with the length of the semiconductor fin and is spaced apart from the semiconductor fin. The gate endcap isolation structure also has a second portion in a location of the cut of the semiconductor fin and in contact with the semiconductor fin.
