    Abstract: Disclosed herein are quantum dot devices, as well as related computing devices and methods. For example, in some embodiments, a quantum dot device may include: a base; a fin extending away from the base, wherein the fin includes a quantum well layer; and one or more gates disposed on the fin. In some such embodiments, the one or more gates may include first, second, and third gates. Spacers may be disposed on the sides of the first and second gates, such that a first spacer is disposed on a side of the first gate proximate to the second gate, and a second spacer, physically separate from the first spacer, is disposed on a side of the second gate proximate to the first gate. The third gate may be disposed on the fin between the first and second gates and extend between the first and second spacers.

    Abstract: A method for performing a spacer etch process is described. The method includes conformally applying a spacer material over a gate structure on a substrate, and performing a spacer etch process sequence to partially remove the spacer material from a capping region of the gate structure and a substrate region on the substrate adjacent a base of the gate structure, while retaining a spacer sidewall positioned along a sidewall of the gate structure. The spacer etch process sequence may include oxidizing an exposed surface of the spacer material to form a spacer oxidation layer, performing a first etching process to anisotropically remove the spacer oxidation layer from the spacer material at the substrate region on the substrate and the spacer material at the capping region of the gate structure, and performing a second etching process to selectively remove the spacer material from the substrate region on the substrate and the capping region of the gate structure to leave behind the spacer sidewall on the sidewall of the gate structure.

The second dielectric material is chemically bonded across a transition region to the first dielectric material.
