Abstract: Non-planar semiconductor devices having self-aligned fins with top blocking layers and methods of fabricating non-planar semiconductor devices having self-aligned fins with top blocking layers are described. For example, a semiconductor structure includes a semiconductor fin disposed above a semiconductor substrate and having a top surface. An isolation layer is disposed on either side of the semiconductor fin, and recessed below the top surface of the semiconductor fin to provide a protruding portion of the semiconductor fin. The protruding portion has sidewalls and the top surface. A gate blocking layer has a first portion disposed on at least a portion of the top surface of the semiconductor fin, and has a second portion disposed on at least a portion of the sidewalls of the semiconductor fin. The first portion of the gate blocking layer is continuous with, but thicker than, the second portion of the gate blocking layer. A gate stack is disposed on the first and second portions of the gate blocking layer.

Abstract: Techniques for providing non-volatile antifuse memory elements and other antifuse links are disclosed herein. In some embodiments, the antifuse memory elements are configured with non-planar topology such as FinFET topology. In some such embodiments, the fin topology can be manipulated and used to effectively promote lower breakdown voltage transistors, by creating enhanced-emission sites which are suitable for use in lower voltage non-volatile antifuse memory elements. In one example embodiment, a semiconductor antifuse device is provided that includes a non-planar diffusion area having a fin configured with a tapered portion, a dielectric isolation layer on the fin including the tapered portion, and a gate material on the dielectric isolation layer. The tapered portion of the fin may be formed, for instance, by oxidation, etching, and/or ablation, and in some cases includes a base region and a thinned region, and the thinned region is at least 50% thinner than the base region.
