Abstract
Structures for a semiconductor device that include dielectric isolation and methods of forming a structure for a semiconductor device that includes dielectric isolation. A semiconductor body includes a cavity, first and second gate structures extending over the semiconductor body, and a semiconductor layer including first and second sections on the semiconductor body. The first section of the semiconductor layer is laterally positioned between the cavity and the first gate structure, and the second section on the semiconductor layer is laterally positioned between the cavity and the second gate structure. An isolation structure is laterally positioned between the first and second sections of the semiconductor layer. The isolation structure includes a dielectric layer and a sidewall spacer having first and second sections. The dielectric layer includes a first portion in the cavity and a second portion between the first and second sections of the sidewall spacer.
