Abstract: An integrated circuit structure includes a sub-fin having (i) a first portion including a p-type dopant and (ii) a second portion including an n-type dopant. A first body of semiconductor material is above the first portion of the sub-fin, and a second body of semiconductor material is above the second portion of the sub-fin. In an example, the first portion of the sub-fin and the second portion of the sub-fin are in contact with each other, to form a PN junction of a diode. For example, the first portion of the sub-fin is part of an anode of the diode, and wherein the second portion of the sub-fin is part of a cathode of the diode.
