Abstract: Semiconductor devices with isolated body portions are described. For example, a semiconductor structure includes a semiconductor body disposed above a semiconductor substrate. The semiconductor body includes a channel region and a pair of source and drain regions on either side of the channel region. An isolation pedestal is disposed between the semiconductor body and the semiconductor substrate. A gate electrode stack at least partially surrounds a portion of the channel region of the semiconductor body.
