Abstract

Device structures for a field-effect transistor and methods of forming a device structure for a field-effect transistor. A trench isolation region is formed in a substrate, and surrounds a semiconductor body. An undercut cavity region is also formed in the substrate. The undercut cavity region extends laterally beneath the semiconductor body and defines a body pedestal as a section of the substrate that is arranged in vertical alignment with the semiconductor body.
